About Us

Ajax Plumbing Supply was established in 1955 by the Salinas family as a television, appliance, and plumbing supply store.

Throughout the years it evolved to be a leading local provider of plumbing supplies in San Antonio and the surrounding areas including Bexar County, Kendall County, Blanco County, Comal County, Guadalupe County, and Atascosa County.

Today, the store remains a Salinas family legacy and is known locally as the go-to specialty store for hard to find parts for older plumbing fixtures.

Considerable savings is passed to customers given the long-standing relationships Ajax Plumbing Supply has with national wholesalers and distributors giving them preferrable pricing.

Ajax Plumbing Supply purchases so many water heaters that their price rivals some of the "big box" stores making Ajax the place to go for water heaters in San Antonio with the best water heater prices in town-- not to mention an all around fair and affordable pricing policy.

Nothing Beats a Cold Shower (Except a Warm one)

Sub-zero degree plunge pools may be the "breakfast of champions" with gurus like Tony Robbins touting the health benefits, but most of us enjoy the comfort of a nice warm shower in the morning over anything else.

In fact, the hassle factor of being out of hot water ranks right up there with getting a flat tire or finding out your dog ate your homework.  Nothing makes you want to crawl back in bed more than the sudden jolt you get when ice cold water replaces the steam you expected.  

Should you find yourself in the unfortunate situation of being out of hot water, in short supply of warm water, or simply experiencing unpredictable water temperatures during your morning shower there is a quick solution.

Reach out to AJAX as soon as possible at 210-434-2303 and we will steer you in the right direction over the phone—whether it be to get your water heater serviced by a licensed plumber or in some cases replace the unit.

​We may recommend your existing water heater unit be inspected for fixes an experienced professional plumber will know how to troubleshoot. Oftentimes you can avoid a new water heater installation with a thorough cleaning of the water heater and removing build-up called "scales." Other times the unit may just need the water heater temperature gauge adjusted.  

Some choose to add an additional water heater to the home depending on the square footage of your home, the number of restrooms, and the size of your family. The longevity of both units will be increased because undo stress won't be put on a single unit that perhaps should have been a larger sized unit from the start.  Afterall, many homes have one or two 50 gallon water heaters even though one 40 gallon water heater is the standard for most homes.

If your water heater is over 10 years old (or close) you may want to avoid repeated service charges, mounting maintenance costs, and just "bite the bullet" with a replacement water heater unit and have a water heater installer fix your family up once and for all.  

Whoever said, "nothing beats a cold shower," was wrong  in our book.  At Ajax Plumbing Supply we will always shoot you straight with our complete offering of water heaters in San Antonio to fit every household and commercial need.  We carry Bradford, Rheem, and A.O. Smith Water Heaters with even more brands of water heaters connections and parts available at our local San Antonio plumbing parts store. 

​As mentioned 40 gallon water heaters are most common and considered standard, but there are also 50 gallon water heaters, 40 gallon low boy water heaters.

​Energy efficiency is also a major consideration when selecting a new water heater.  Many homes are plumbed for gas or electric, but a professional San Antonio plumber can hook you up with either connection depending on your budget.  In the long run a gas water heater is more energy efficient.  Gas water heaters will also help your family save money on the utility bill.
