Expansion tanks - required by code.
We install and replace thermal expansion tanks - protecting your plumbing from pressure damage.
Expansion Tank Installation
Expansion tanks are required by Texas plumbing code on all new water heater installations. Without one, thermal expansion can damage your plumbing system, fixtures, and water heater. We install them on all new water heaters as needed and retrofit them to existing systems when appropriate.
Many homeowners are unaware they need an expansion tank. We check for this on every water heater call.
When to call.
How it works.
We determine whether your system is open or closed and whether an expansion tank is required.
Expansion tanks must be sized based on system pressure and water heater capacity.
Installed on the cold water supply line near the water heater, pressure-checked and verified.

Often yes. A dripping T&P valve is a classic sign of thermal expansion with nowhere to go.
