An expansion tank needs the right air pressure inside to do its job. Here is how Shelton homeowners can check it.
Why the air pressure matters
The expansion tank is split by a bladder: air on one side, water on the other. The air pressure must match your home's water pressure, or the tank cannot absorb expansion.
The quick test
Tap the tank gently. The air side should sound hollow and the water side dull. A tank that is full of water feels heavy and uniform.
Checking with a gauge
With the water supply off and a faucet open to relieve pressure, a tire gauge on the tank's valve reads the air charge. It should match the system pressure.
When to replace
A tank whose valve releases water is waterlogged and needs replacing. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Shelton, a pro can check it during a water heater service.
Keep the system balanced
