Water expands as it heats, and in a closed plumbing system that expansion needs somewhere to go. Here is the Oxnard homeowner's guide.
What thermal expansion is
When water heats, its volume increases. In a closed system — one with a check valve or backflow preventer — that extra volume raises the pressure in the pipes.
Why it matters
The pressure spikes every time the water heater runs, straining the tank, fittings, and fixtures, and it can make the relief valve drip.
The solution
An expansion tank gives the expanding water somewhere to go, absorbing the pressure and protecting the system.
The signs
A dripping relief valve, banging pipes, and failing fittings are the classic symptoms. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Oxnard, a pro can test the pressure and size the tank.
Protect the system
