You can replace a corroded water valve without any soldering
In short: Replacing a faulty shut-off valve doesn't require professional-grade welding or complex plumbing knowledge. This guide demonstrates how to swap out old, corroded components using basic tools and compression fittings.
Contractor Richard Trethewey explains a straightforward method for replacing water-supply valves by cutting the pipe on either side of the old unit with a mini hacksaw. By using new stop-and-waste valves and compression fittings, homeowners can complete the repair without soldering.
The process involves buffing the pipes clean with emery cloth before installation. Once the new valve is positioned between the cut ends, it is secured with an adjustable wrench and pliers. The final step ensures the system is watertight by checking for leaks after turning the water back on.
