How to Fix a Galvanized Pipe

Although there was a time in America when galvanized pipes were used extensively in home plumbing systems, they are rarely (if ever) used in newer homes. Part of the problem with galvanized pipes is the fact that they have the tendency to react with minerals contained in the water, which develops scale buildup that can lower water pressure, cause clogged drains, and even affect the water quality in your home. Galvanized pipes can also corrode from the inside out over time, which means cracks and potentially costly water leaks. Although your best option is to have your Northridge plumber repipe your galvanized plumbing system, there might be scenarios in which you simply need to fix a small area of piping. In that case, here are some tips for fixing a galvanized pipe that has become damaged or busted.

Turn Off Water Supply
First, make sure you turn off your home’s water supply. The last thing you want to do is unscrew a fitting or cut off a piece of damaged pipe only to deal with a sudden rush of water inside your home. If you aren’t sure where the water shut-off valve is located, take a minute to find out so you know how to turn off your water supply in the event of a plumbing emergency.

Estimate Condition of Nearby Pipes
Before you proceed with repairs, estimate the condition of the galvanized pipe near the damaged section you are working on. If it appears that other areas of the pipe may soon develop a leak, or if corrosion is very bad, consider getting an estimate on replacement piping services instead. In some cases you might be able to save a lot of money in the long run by replacing galvanized plumbing now instead of paying for multiple plumbing repairs down the line.

Replace the Damaged Section
If you only need to replace a small section of pipe, carefully cut the damaged section out on both sides using a reciprocal saw. Next, screw a female PEX or PVC fitting on both ends. Finally, install the carefully measured piece of PEX or PVC plumbing into the fittings and brush a waterproof sealer on the fittings to prevent leaking.
