An expansion tank is a small device that prevents a common and expensive problem: pressure spikes every time your water heater runs. Here is what Amherst Town homeowners should know.
What it does
Water expands as it heats. In a closed plumbing system, that expansion has nowhere to go, so pressure climbs and can strain the water heater, fittings, and fixtures. An expansion tank gives the extra volume a place to go.
Why closed systems matter
Many Amherst Town homes now have a check valve or backflow preventer at the meter, which turns the system into a closed one. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In a closed system, an expansion tank is not optional if you want the heater and pipes to last.
The warning signs
A dripping temperature-and-pressure relief valve on the water heater is the classic clue. That valve is doing its job by releasing excess pressure — but if it has to keep doing that, something is wrong.
Sizing and install
The tank is sized to your water heater and home. It installs on the cold water supply line near the heater, and a pro checks the air pressure inside to match your home's water pressure.
Cheap protection
Compared with a water heater replacement or a burst fitting, an expansion tank is inexpensive protection. Call 888-217-3585 and Amherst Town Plumber Connect will match you with an Amherst Town pro who can confirm whether your home needs one.
