Frequently Asked Questions

Most homeowners should schedule water testing at least once per year. If you live in San Antonio or the surrounding Central Texas areas, annual testing helps monitor changes caused by environmental factors, aging plumbing, and seasonal shifts. Homes on private wells should always test anytime water taste, color, or odor changes.

A professional water quality test can identify a wide range of issues, including hard water minerals, chlorine, sediment, iron, pH imbalance, bacteria, heavy metals, and chemical contaminants. Testing is the only reliable way to know what is actually in your water before choosing a treatment system.

Hard water testing focuses specifically on mineral levels, usually calcium and magnesium, in water, which cause scale buildup, appliance damage, and soap scum.

We prefer to meet with you at your home to conduct our own review of your plumbing and water quality. This helps us ensure that our recommendations are right for your water needs and property. We can also conduct a free in-home water test to identify common issues.

However, in some cases, we’re able to provide a rough service quote over the phone, email, or even a virtual call if that’s easier for you. If you’re on municipal water, a good starting point is checking your annual water quality report. From there, we can help guide you toward the best option for your home.

Yes. While municipal water is treated, it can still contain high chlorine levels, hard minerals, sediment, or aging pipe contaminants. Water testing helps identify issues that affect taste, odor, plumbing performance, and skin or hair health, even when water meets basic safety standards.

Free water testing is an excellent way to identify common issues like hard water, chlorine, iron, and TDS. For more complex water quality concerns, such as bacteria, PFAS, or lead, laboratory testing provides a deeper analysis.

You should consider water testing if you notice:

• White scale buildup on fixtures
• Rust stains throughout your home
• Sediment or flecks in water
• Tarnished silverware
• Dry skin or hair after showering
• Cloudy, discolored, or smelly water
• Water that has a metallic flavor or otherwise tastes “off”
• Spotty dishes or soap that doesn’t lather
• Appliance issues
• Stains on laundry or stiff, scratchy clothes
• Rings in tubs and toilets
• Staining in sinks, tubs, showers, and toilets
• Poor water pressure
• Frequent plumbing issues

These are often signs of underlying water quality problems. Contact Alamo Water Softeners for free water testing!

Water testing ensures you do not over- or under-treat your water. Based on results, Alamo Water Softeners can recommend a water conditioner, reverse osmosis system, carbon filtration, or whole-home filters designed specifically for your water conditions.

Yes, we can. We offer water quality testing to help you understand what’s in your water supply and what might be affecting your home. It’s the best way to make sure you’re getting the right solution for your specific needs. Schedule your water test with our trained professionals today!

Yes, you can absolutely get a water filter for your entire home. A whole-home filtration system is installed where water enters your house, allowing it to filter all the water used throughout your property, not just at one sink. This means cleaner, better-tasting water for drinking and cooking, as well as filtered water for showers, laundry, and appliances.

Whole-home systems require the same occasional maintenance as any point-of-use filter. Schedule professional maintenance and filter changes based on the needs of the equipment you choose.

If you have a whole-home softener system, you’ll simply need to top off the brine tank every 1-3 months with salt and schedule periodic service checks. When you sign up for a membership with us, we handle routine tasks, including inspections and salt delivery.

A reverse osmosis water filtration system and a whole-house water filtration system are both designed to improve your water, but they often serve different purposes.

An RO system is typically installed at a single tap, like your kitchen sink. These filters have a special membrane with a pore size of around 0.0001 micron. RO systems remove a wide range of contaminants that many other filters miss, giving you great-tasting, nearly pure drinking water.

A whole-house filtration system treats all the water coming into your home. It can be a reverse osmosis system, but usually it’s a softener or specialty filter. Whole-house units typically help reduce things like chlorine, odors, and sediment so your water is cleaner for bathing, cooking, and everyday use.

Many homeowners still choose RO for drinking water because it provides an additional level of purification at the point of use.

The best size filtration system for your home will depend on your household needs, number of fixtures, and water quality. Alamo Water Softeners provides a free in-home analysis to determine what size will work best for your property.

No. A water filter system from Alamo should not noticeably reduce water pressure.

Water pressure is extremely important. If pressure is too high, your softener and water filters won’t have a chance to work properly, since water could be passing through too quickly. High pressure can also put extra strain on your equipment and lead to wear over time. Your home’s water pressure should be set anywhere between 60 and 80 psi.

Professional installation ensures that your system is calibrated for local water pressure and hardness levels. A local reverse osmosis installer like Alamo Water Softeners ensures all connections are leak-proof and that the system is integrated correctly with your plumbing.

Most homeowners notice a change in the taste or smell of their water when filters become saturated. You may also see a significant drop in water pressure at the dedicated faucet. We recommend scheduled filter replacement every 6 to 12 months to avoid these issues.

Most RO filters are replaced annually, depending on water quality and usage. Filter replacement schedules and costs are reviewed during installation.

For a whole-house RO system for well water or city water, the membrane typically lasts between 2 and 5 years. This timeline depends heavily on your daily water usage and the quality of the water entering the system. Staying consistent with RO water filter replacement and maintenance is the best way to extend the life of the membrane.

A carbon filter reduces chlorine, chloramine, and bad tastes and odors, improving the flavor and smell of your home’s water. It also traps volatile organic compounds (VOCs).

Yes, we provide whole-house RO system well water installations across the San Antonio area. These systems are designed to handle the specific contaminants found in local groundwater, providing bottled-quality water throughout your home.

This can be caused by a ruptured tank bladder, a clogged filter, or another issue. Contact Alamo Water Softeners for service. Our technicians can quickly diagnose the problem and restore your reverse osmosis system to full functionality.

Yes. RO systems can be plumbed to supply refrigerators for ice and drinking water.

Most importantly, our relationship doesn’t end after installation. We’re here to support you for the long haul. Take a look at our Google reviews and client testimonials, as they really do say it best.

Yes, it can. Hard water leaves behind mineral buildup inside your appliances and plumbing, which can make them work harder and wear out faster.

Over time, that buildup can lead to higher energy use, more repairs, and a shorter lifespan for things like your water heater, dishwasher, and washing machine. Soft water doesn’t contain excess minerals, so your equipment can run more efficiently and last longer.

Yes, a water softener can benefit you and your home in many ways. Hard water leaves behind minerals that can dry out your skin and hair, cause buildup on dishes, shower doors, and fixtures, and even clog pipes. With a softener, those minerals are removed.

Your skin and hair shouldn’t feel as dry, and you should feel cleaner after a shower with soft water. You’ll also notice less spotting and soap scum on glass, cleaner fixtures, and better soap lathering. Cleaning also becomes easier since you’re not fighting constant buildup.

Water softeners use water during regeneration, but modern systems are designed to be highly efficient. In many homes, reduced scale buildup can actually improve overall plumbing efficiency over time.

Yes, we offer financing options to help make things more manageable if you’re not ready to pay everything up front. During your appointment, one of our technicians will walk you through the options and help you find what works best for your home and budget.

Yes, we do. Our rental options are designed to give you the benefits of better water without the upfront investment. Your monthly cost will depend on your home and your family’s water needs. We’ll walk you through choosing the best option and keep things simple. Contact us to schedule a free, no-obligation evaluation.

Most water softener systems require approximately a 3′ × 3′ area to accommodate both the resin tank and the brine tank, along with proper plumbing connections and service access. Systems are commonly installed in garages, utility rooms, or designated plumbing areas. If space is limited, Alamo Water Softeners can recommend alternative system configurations to fit tighter installation areas or shed options without sacrificing performance.

A water softener requires access to the main water line, a drain for regeneration discharge, and a nearby electrical outlet. If your home is not pre-plumbed, we can professionally add a softener loop or modify the plumbing as needed. Roughly half of the homes we service were not pre-plumbed prior to installation.

Yes. We routinely install systems in homes that are not pre-plumbed. Our technicians evaluate the best installation location and handle all necessary plumbing modifications as part of the process.

Yes, we can. A lot of homes aren’t set up for a water softener, but that’s something we handle all the time. Somewhere around 50% of our customers’ homes were not plumbed for softeners at first, and now they are. We’ll walk you through how to get everything set up properly. Contact us to schedule a free, no-obligation evaluation.

Alamo Water Softeners can install the highest quality water treatment systems in your home or business, whether you’re on a well or your water is supplied by a municipality. Well water does have larger variances in quality, so it’s recommended to start with a comprehensive lab analysis. We provide that service, as well as on-site water testing when appropriate.

Most families in San Antonio can expect a whole-home water softener installation to start in the $3,000–$5,000 range. Final pricing depends on factors such as household size, water hardness levels, plumbing configuration, and whether advanced features like filtration or WiFi-enabled monitoring are included. A free water test is the best way to determine the right system and exact cost for your home.

We recommend having your water softener serviced about once every three years to keep it running efficiently.

We do offer a membership program that includes routine maintenance along with savings on several plumbing services. It’s a simple way to stay ahead of issues and protect your investment. Contact us to learn more.

Water softeners do not last forever. However, many systems can last over 20 years with proper maintenance. Contact us for a system check to see how well your current system is performing.

In most cases, yes. A water softener is designed to remove hard minerals like calcium and magnesium, but it doesn’t take out things like chlorine, chemicals, or other contaminants.

If you’re noticing taste, odor, or appearance issues, or you simply have concerns about what’s in your water, a whole-home water filter is the proper solution. Many homeowners choose to use both filters and softeners so they get the benefits of soft water and cleaner, better-tasting water throughout their home.

Yes. During regeneration, single-tank systems temporarily provide unsoftened water, while dual-tank systems continue delivering soft water without interruption.

A softener loop is a section of plumbing that allows water to be routed through the water softener before entering the home. During your evaluation, we’ll show you where the loop would be installed and explain how it integrates with your existing plumbing.

Resin is the filtration media inside the water softener that removes hardness minerals like calcium and magnesium through an ion-exchange process. It is essential to producing soft water throughout your home.

Resin typically lasts 10–15 years, depending on water quality, chlorine levels, and maintenance. Homes with high chlorine or iron may require replacement sooner.

Regeneration is the self-cleaning cycle of a water softener where the system flushes accumulated hardness minerals from the resin using a salt brine solution, restoring the resin’s ability to soften water. This process is typically scheduled overnight because household water usage is lowest at that time, minimizing disruption and ensuring soft water is available during peak daytime hours.

Water pressure is extremely important. If pressure is too high, your softener and water filters won’t have a chance to work properly, since water could be passing through too quickly. High pressure can also put extra strain on your equipment and lead to wear over time. Your home’s water pressure should be set anywhere between 60 and 80 psi.

When the power goes out, it’s normal for your water softener clock to reset. Updating the time is usually quick and only takes a minute or two. We’ve put together a simple step-by-step video to walk you through it. Just click here to watch the tutorial on our YouTube page and get your system back on track.

Outdoor hose bibs are typically left on unsoftened (hard) water, which is ideal for plants and landscaping. Water softeners are designed to treat indoor household water only, preserving naturally occurring minerals for irrigation and ensuring landscaping is not affected by softened water.

Any type of water softener salt will work for your system. However, pelletized salt has bonding agents in it in order to create the pellet. The solar crystal salt does help your system operate better. Most systems work best with high-quality pellet or crystal salt. These types help your system run efficiently and limit buildup over time. If you’re not sure what type is best for your softener, we’re happy to help. Contact us today, and we’ll point you in the right direction. We also offer water softener salt delivery for your convenience.

Alamo Water Softeners delivers high-quality, septic-safe salts that protect both your system and your home’s plumbing. We offer solar salt, which is naturally evaporated and ideal for efficient softening. We also carry potassium chloride, an eco-friendly and sodium-free alternative.

We recommend solar crystal salt because it dissolves cleanly and supports optimal system performance. Pelletized salt will work, but it contains binding agents that can contribute to buildup over time.

Water softener salt delivery eliminates the hassle of buying, storing, and lifting heavy salt bags. Our San Antonio delivery team ensures you always have the right salt for your system, keeps your brine tank filled, and performs a basic maintenance check during each visit. This means better system performance, improved water quality, and one less chore to remember.

Yes, when you sign up for salt delivery with AWS, our delivery team will refill the brine tank. They will also verify that the system is running properly before they leave. These services are included when you sign up for a maintenance membership plan.

Adding salt is simple and requires no tools. During installation, our technicians show you exactly how to add salt and how to monitor levels.

Most families need fresh salt every two to three months. However, the amount of salt your system uses depends on water usage. Large households may need salt added more often than smaller ones. Our technicians can help you determine the best salt delivery schedule for your needs.

If you notice side effects of hard water, like spots on dishes, buildup on faucets, or dry skin after showering, your softener could be low on salt. You might also notice your brine tank looks low or completely empty.

If your softener is already filled, Alamo Water Softeners can perform a water test to confirm whether your system is regenerating properly.

Water softener salt costs vary by retailer and type but is generally affordable and widely available at home improvement stores and grocery retailers. To make ownership even easier, Alamo Water Softeners offers a convenient salt delivery program, so you don’t have to lift, transport, or store heavy bags. Delivery options are customized based on your household’s usage and water conditions.

Yes, we do. Water softener salt delivery from AWS takes the hassle out of keeping your softener running properly. We’ll deliver the salt right to your home, so you don’t have to worry about lifting heavy bags or making extra trips to the store. Contact us today, and we’ll walk you through how our salt delivery program works.

In Central Texas, most traditional tank water heaters last between 8–12 years, while tankless water heaters can often last 15–20 years with proper maintenance. Hard water in areas like San Antonio, Bulverde, Spring Branch, and New Braunfels can shorten the lifespan of a water heater due to mineral buildup inside the tank and heating elements. Regular flushing and water heater use can help extend the life of your system.

The right size tankless water heater depends on how many fixtures and appliances you use at the same time. A small household may only need a unit capable of handling 5–7 gallons per minute, while larger homes with multiple bathrooms often require higher-capacity systems or even multiple units. Factors like incoming groundwater temperature and family size also matter. A professional assessment from Alamo Water Softeners can help ensure you get the correct size for reliable hot water.

Most water heaters have a thermostat that allows you to adjust the temperature. On electric water heaters, the thermostat is usually located behind access panels. On gas water heaters, there is typically a temperature dial near the gas control valve. For safety and energy efficiency, most homeowners should keep the temperature set around 120 degrees Fahrenheit.

A standard water heater installation usually takes about 2–4 hours. Tankless water heater installations may take longer depending on gas line upgrades, venting requirements, or electrical modifications. Installation time can also vary if plumbing updates or code corrections are needed.

Replacing an existing water heater with a similar model generally takes between 2–4 hours. If additional work is required, such as updating venting, adding an expansion tank, or converting to tankless, the process may take longer. Alamo Water Softeners has professional installers that can usually complete most residential replacements in a single visit.

You should consider replacing your water heater if it is over 10 years old, leaking, producing rusty water, making loud popping noises, or struggling to provide consistent hot water. Rising utility bills and repeated repairs can also be signs that replacement is more cost-effective than continued repairs. At Alamo Water Softeners, we often help homeowners extend the life of their water heaters through water softening and routine maintenance solutions designed specifically for Texas water conditions.

There are several possible reasons your water heater may stop working, including a tripped breaker, failed heating element, pilot light issues, thermostat failure, gas supply problems, or sediment buildup. If you suddenly have no hot water, it is best to have the system professionally diagnosed to avoid further damage or safety risks.

Most electric water heaters have a reset button located behind the upper access panel on the unit. If the water heater stops heating, pressing the reset button may restore operation temporarily. However, if the reset button continues to trip, it could indicate a faulty thermostat or heating element that requires professional repair.

Most manufacturers and plumbing professionals recommend setting your water heater to 120 degrees Fahrenheit. This temperature provides comfortable hot water while helping reduce energy costs and lowering the risk of scalding. Some households may choose slightly higher settings for larger hot water demands, but temperatures above 140 degrees can become dangerous.

Traditional tank water heaters typically take 30–60 minutes to fully heat a tank of water after being depleted. Gas models generally heat faster than electric models. Tankless water heaters heat water almost instantly as it flows through the system, though there may still be a short delay as hot water travels through the pipes.

If your water heater is leaking from the bottom, turn off the power or gas supply and shut off the water valve to the unit if possible, or if you need assistance, call Alamo Water Softeners. Leaks may come from loose drain valves, condensation, or internal tank failure. A leaking tank often indicates the water heater needs replacement, especially if the unit is older.

Regular water heater maintenance includes flushing the tank annually to remove sediment, checking the anode rod, inspecting for leaks, testing the pressure relief valve, and monitoring temperature settings. In Central Texas, hard water makes routine maintenance especially important to help extend equipment life and maintain efficiency. Alamo Water Softeners commonly recommends water treatment solutions alongside regular maintenance to help reduce scale buildup and improve overall appliance longevity.

In many Texas homes, an expansion tank is required when a closed plumbing system is present. Expansion tanks help protect your plumbing and water heater from pressure buildup caused by heated water expanding inside the system. Local plumbing codes and home configurations can vary, so a licensed professional can determine whether one is needed for your installation. At Alamo Water Softeners, we help ensure systems operate safely and in compliance with local Texas plumbing requirements.

Water heater replacement costs can vary based on the type of unit, your home’s plumbing setup, and whether any upgrades are needed during installation.

As a general guideline:

• Traditional gas or electric water heaters usually range from $2,600 to $3,500
• Tankless water heater installations typically start around $5,500

For the most accurate pricing, contact Alamo Water Softeners for a free estimate tailored to your home and hot water needs.

Systems can often be removed and relocated. If left with the home, warranty transferability depends on system type and agreement terms.

Common signs include spotting on fixtures, dry skin or hair, soap not lathering well, or scale buildup returning. Any noticeable change in water quality warrants a system check.

If a system is older, inefficient, or experiencing repeated failures, replacement may be more cost-effective long term. We provide honest recommendations after evaluating your system.

Yes, we can. Installing during the build process is actually one of the best times to do it, since everything can be set up the right way from the start. We’ll work with you or your builder to make sure everything is properly installed and ready to go when you move in. Schedule a free, no-obligation evaluation when you contact us today.

Yes, they do. We stand behind the products we install, and our warranties are one of the things our customers appreciate most. If you ever have a question or need help, our team is here for you.

In many cases, yes. We’re happy to take a look and see if a repair makes sense or if there’s a better long-term option for your home. Contact us to schedule a system inspection.

Most installations are completed in one day. Timing depends on plumbing requirements and system type, all of which are reviewed during your evaluation.

Most installations do not require trenching. Trenching is only needed when the main water line or drain access is located far from the installation area, such as in detached garages or exterior wall setups. If trenching is required, we review scope and cost with you upfront before any work begins.

If you are on city water, your provider publishes an annual Consumer Confidence Report (CCR) outlining detected contaminants. Independent resources such as the Environmental Working Group (EWG) database can also provide insight. We help interpret this data during your evaluation and verify results with on-site testing when needed.
