Water heater leaking in San Antonio? Here's what to do
A leaking water heater can't wait - even a small leak can damage flooring and drywall fast, especially in older San Antonio homes
Signs of a leak:
- Puddle or standing water at the base of the tank
- Water dripping from a fitting, valve, or pipe connection
- Rust-colored water, or visible rust on the tank exterior
- Moisture around the pressure relief valve
- A hissing or dripping sound coming from the unit
Leaking now? Turn off the cold water supply valve on top of the tank, and if it's a gas unit, switch the gas control to "off." Then, call Reliant Plumbing — we run emergency water heater calls around the clock, including nights and weekends.
Common Water Heater Repair Issues We Fix in San Antonio
San Antonio's extremely hard water wears down heating elements and tanks faster - here's what that can look like:
Signs you need a repair:
- No hot water, or it runs out fast
- Inconsistent water temperature
- Popping or rumbling noises
- Pilot light won't stay lit (gas units)
Not sure if it's worth fixing? Most tanks last 8–12 years. Our licensed plumbers diagnose the issue on-site and give you a flat, upfront price before any work starts — no guessing, no surprise charges.
The Ultimate Guide to Water Heaters
San Antonio's mineral-heavy hard water can act like sandpaper on the interior elements of your water heater.

Our team can be out today to fix the issue before it turns into a more expensive disaster.
