Common Questions

Frequently Asked Questions

Clear answers to common questions about plumbing diagnostics, hydrostatic testing, and home HVAC services across San Antonio.

What is hydrostatic plumbing testing, and when do I need it?

Hydrostatic testing isolates and pressurizes your underground sewer and drainage system with water to confirm whether an active structural leak exists beneath your foundation. This test is essential before major foundation repairs, following soil movement, or during residential real estate inspections to prevent hidden leaks from eroding the sub-slab.

Common warning signs include an unexplained increase in your water bill, warm spots on tile or hardwood floors, damp baseboards, or the continuous sound of running water when all fixtures are turned off. If you suspect a leak, our team uses non-destructive acoustic equipment and thermal imaging to pinpoint the break without unnecessary demolition.

An exterior mainline cleanout gives our heavy-duty snake and hydrojetting equipment direct access to your primary sewer lateral. Without a cleanout, technicians often have to remove indoor toilets or work through roof vents to clear main sewer line clogs, which increases service time and risks interior mess.

Yes. San Antonio’s water supply comes primarily from limestone formations in the Edwards Aquifer, making it among the hardest municipal water in Texas. A whole-home water softener eliminates mineral scale buildup, prevents early water heater element burnout, and protects fixtures, faucets, and appliances throughout your home.

In Texas, plumbing and HVAC trades are governed by separate state regulatory bodies. Hydrostatic Plumbing & Air holds dual credentials: our plumbing operations are licensed by the Texas State Board of Plumbing Examiners (TSBPE RMP #43692), while our heating and cooling services are regulated by the Texas Department of Licensing and Regulation (TDLR TACLA00139580E).

I had a hydrostatic plumbing test performed on my house by the Master Plumber, Alfredo Vallejo. He did an excellent job! To properly pressurize and test the sewer lines, he had to remove a toilet. After allowing sufficient time for the test, he promptly shared the results—much to my relief, everything passed! He also inspected the inside of the sewer lines with a camera and showed me the video footage. He noticed that the wax ring beneath the toilet needed to be replaced and took care of it without hesitation, which was truly above and beyond. He was professional, thorough, trustworthy, and highly recommended.
