Why are my copper water pipes turning green?
Green – Green or greenish colors on the outside of your copper water pipes means that you have water leaks in your copper piping and possible corrosion. The latter is especially true if the water itself is staining other items, like clothing, sinks, and fixtures.
How do you protect copper pipes from corrosion?
Ideally, a thin, smooth film of limescale forms inside the pipe along the wall and protects the copper from corrosion. Unfortunately, if the amount of calcium carbonate in the water is too high, this is not possible and copper pipes can clog just as any other pipe.
Does copper react with galv?
Copper and Brass If an installation requires contact between galvanized materials and copper or brass in a moist or humid environment, rapid corrosion of the zinc may occur. Even runoff water from copper or brass surfaces can contain enough dissolved copper to cause rapid corrosion.
What to do if you have a faulty water valve?
Remove any supply lines that lead from the faulty valve. After shutting off the water and draining the system, use a pipe wrench to loosen any supply lines that lead from the valve to fixtures. These supply lines are usually flexible braided pipes, and they run from the valve to a faucet or toilet.
What kind of valve do I need to replace my water line?
A threaded valve screws directly onto the water supply line and is easy to replace. In a compression connection, the valve screws into a hexagonal nut that fits around the supply line. The most difficult type to replace is a sweat valve, which is soldered onto the supply pipe.
What to do if your water valve is rusted?
Inspect the exposed threaded supply line. With the old valve removed, check inside the pipe for rust or corrosion. Ensure the threads are intact and will be able to receive the new valve. Call a plumber if your pipe is rusted or if the threads are rotted.
Why is my cold water expansion valve not working?
Also, if you manually turn on the cold water expansion valve to discharge water (turn blue knob) look for discoloration of the water as this indicates the valve is rusted internally or the rubber seal has perished and is no longer effective. Why not book in a hot water cylinder service to do a full system check?

When is the best time to replace a water valve?
If you have an older home with original plumbing, it’s wise to have a professional replace valves. If you remove the valve and find that the pipe is internally rusted or threads are rotted, have a plumber install a replacement supply pipe. Purchase a valve that fits the supply lines.
