Below, learn nine types of under-sink shutoff valves and their purposes to help you identify the valves in your home when replacing or repairing your plumbing fixtures. Iron pipe valves simply screw and unscrew from the end of the pipe. The only tools required are two pliers: one to hold the pipe in place, and the other to tighten the valve. Chrome-plated brass versions are available, which cost significantly less than cast iron stop valves and are more durable over time. PEX stop valves can be removed, but you have to cut off the ring. This often results in damage to the pipe, which usually means the pipe needs to be shorted to get a fresh section of pipe for the new valve. These valves are typically made of brass or chrome-plated brass and can be replaced on a low budget. It’s also important to consider the type of plumbing pipes that your valve will shut off. Various valves are available for copper, PEX, and CPVC pipes, and the correct option should be chosen based on the pipe material. If you’re unsure which type of shut-off valve you need, consult a plumber for help. You can also turn off your home’s main water supply, remove the current valve, and bring it to your local hardware store for a professional to help you find a suitable replacement.
