Never be concerned if your water filter will get rid of the upcoming exotic compound found in your water source. Other manufacturers remove only certain contaminants, which makes you vulnerable. San Antonio water can be full of excess calcium from limestone. Our water filtration systems clean San Antonio water so you can enjoy safe drinking water.

Our multi-phase water filters combine carbon adsorption and reverse osmosis that will address the chemicals and heavy metals that pollute your water.

We’ve been selling NSF approved water filter systems since 2005, and have evaluated dozens of approaches to producing pure, healthy, drinking water. Our study reveals a very considerable issue: every additional water filter on the market leaves you defenseless to one type of contamination or some other. 

Only the proper combination of technology can improve purity. Some San Antonio water filtration systems claim to filter out harmful chemicals but end up falling short. That is where The Water Doctor is here to get you the right water filtration system in San Antonio.

Be sure which ever water filtration system you choose is capable of addressing your water concerns. 

Gadget filters that attach to a faucet or match in a pitcher normally use granular activated carbon or a little carbon block. These products are intended to enhance flavor, aroma, and visual appeal. If you read this fine print you will find their ability to reduce contaminant levels is minimal.

Assess and the difference will be crystal clear–no other water filter or purifier could match our level of contaminant removal. Our water filtration system has been recognized to be a thorough and effective.

The Water Doctor’s water purification system cleans your San Antonio home’s water. Your family deserves drinking water that  meets the standards for purity.

Good hydration is essential to good health, and water is the major medium through which our bodies remove toxins.

Questions & Answers

Make sure your contractor or installer has applied for the correct permit. This protects you, the consumer. There are two types of permits that can be applied for. The types of permits are a Plumbing Permit Application and a Plumbing Limited Service and Repair.

A Plumbing Permit Application– If your home is non pre-plumbed (there is no existing connection for a softener or a loop) and you are inside the city limits of San Antonio, you need a plumbing permit Application. This type of permit is always required by The City of San Antonio when the conditions above are present and it requires an inspection. A Plumbing Permit Application is also required when a home is pre-plumbed (prepared for a softener or has a loop in the garage) and you are installing a water softener for the very first time.

If a previous installation is brought up to code, a Plumbing Permit Application is required because new changes to the existing plumbing are being made.

A Plumbing Limited Service and Repair – If your are replacing a water softener and all existing plumbing is up to code. This permit does not require an inspection.

The ONLY time an inspection is NOT required is when a water softener is being replaced. Because all the connections would have been previously made and inspected from a previous installation, no inspections is needed.

Visit the City of San Antonio and research a contractor or company’s permit history. It is very important to select a company or contractor that is attaining the proper permits from The City of San Antonio. Permit Inspection and Review tab and select contractor. Type in the company’s name.

When in doubt, please call the City of San Antonio at 210-207-1111 and select development Services option. Ask them to research the company in question.

The correct permit will always protect the consumer. The City of San Antonio works hard to protect you by inspecting a company or contractor’s work.

If a loop is being added or your home is non pre-plumbed, The City will inspect the installation to make sure all the plumbing regulations are being followed. This protects you from foundation problems, water contamination, leaks, freezing pipes, broken pipes etc. A cheap job can cost you thousands. On the other hand, just because you are being charged a high price doesn’t necessarily mean the job will be performed by a company with all the regulations required.

Some company’s will apply for the wrong type of permit to avoid an inspection from the city.

Example: The home is Non Pre-Plumbed and the contractor attains a Plumbing Limited Service and Repair permit. In this case, an inspection will be avoided by the Company or contractor you purchased from. Remember, A plumbing Limited Service and Repair does not require an inspection because this type of permit is for replacement of a water softener only and where all pluming is up to code. Being informed, is your best tool for a professional installation.

Do not let anyone cut corners on your project. Most important, make sure you invest your hard earned money in the right company. Staying informed is your best armor when it comes to a professional installation.

Hard water is water with a very high mineral content such as calcium and magnesium. Central Texas has some of the hardest water in the US due to the limestone present in the aquifers we source our water from. This limestone leaves dissolved minerals in our water supply.
The answer is no. The minerals such as calcium and magnesium in our water is practically dissolved rock. Our bodies are not capable of absorbing these large molecules and therefore has to filter them out. The minerals our bodies need for nutrition, we receive from the foods we eat and the supplements we take, not the water we drink. ​
It is easy to spot hard water damage. Sinks and faucets will show hard water spots or calcified build up. Glass shower doors will have a white film on it that is hard to clean off. Drinking glasses and silverware will show water spots after drying. Hard water affects skin and hair by making skin dry and itchy and hair brittle. It affects plumbing by building scale in the pipes. Hard water shortens the life of water using appliances by an average of 30%. Dishwasher elements will be coated in a white calcified build up. Clothes washer drums will clog up with scale and water heaters can accumulate up to 3 feet of calcified build up, drastically increasing energy consumption. Most homes in central Texas will benefit from a water softener, especially homes with hard water symptoms.
Water softeners work on the basis of ion exchange. The water softener tank holds a medium, called resin. These spherical beads look like tiny golf balls with indentations. They carry a charge, like a battery. The dissolved solids in the water also carry a charge. The resin beads will attract the particles in the water like a magnet, and physically hold on to the particles allowing the water to flow through free from these substances, creating soft water.
When the resin beads are full of hard water particles, they have to be cleaned in order to hold on to more particles. When the resin beads are saturated the system will initiate a regeneration cycle. The salt tank will fill with water and mix with the salt in the tank to form a brine solution. This brine solution carries a very strong charge. When the brine solution rinses over the resin beads it will push the hard water particles off of the resin bead making room for more hard water particles. When the resin beads have been cleaned, the hard water particles and excess sodium is rinsed out and down the drain. The system returns to service. Therefore the salt is only used for cleaning of the resin, not for softening the water.
No, the home does not have to be pre-plumbed. When a home is pre-plumbed for a water softener, it simply means that the inside and outside plumbing has been separated to allow only water inside the home to be conditioned, leaving the outside water hard. It is just as easy to install a water softener when the home has not been pre-plumbed. The installer will simply cut into the main water line. The only difference is that all the water going to the home will be soft. However, we leave a hard water hose bib outside for watering the lawn. We also leave hard water lines for a sprinkler system. The best part is, we do not charge for installation. Pre-plumbed or not, installation is included in our price!
