Frequently asked questions
PEX or copper — which is better?
Both are approved and widely used. PEX is flexible and faster to install; copper is durable and familiar. Cost, access and preference usually decide.
How do I know if I have galvanized pipes?
Galvanized steel is grey, threaded at joints and attracts a magnet. Copper is reddish-brown and non-magnetic.
Should I repipe my whole house?
If you're having repeated leaks or rusty water from old galvanized lines, repiping may cost less over time than ongoing repairs. Get an assessment first.
What causes pipes to bang?
Usually water hammer — sudden pressure surges when valves close quickly — or loose pipe supports.
