How to Replace a Leaking Stop Valve Under Your Kitchen Sinks?

If you have a countertop or table mount faucet fixed in your kitchen sink, it is natural that you would also have stop valves, concealed stop cock faucets or angle valves underneath the sink to regulate the flow of water into the kitchen sink faucet.

Brass Kitchen sink fittings like the stop valves or the angle valves can be left unattended for a long time without them causing any issues like leakage or cracking due to their robust composition. But you should always make sure that once your stop valve becomes problematic, you change it immediately before it causes any damage to your cabinets underneath the sink and ultimately prevent wastage of water.

How To Replace A Leaking Stop Valve Under Your Kitchen Sinks

If your shut-off valve needs a replacement, here’s how you deal with it.

Following are some steps you could follow:

  • Identify & Consult

The first thing you need to keep in mind is the kind of stop valve or angle valve that needs to be replaced. The reason is the only thing you will be replacing is the stop valve faucet and not the entire arrangement. Therefore, you need to correctly identify the kitchen fitting and the name of the fitting so that you purchase the appropriate new angle valve or concealed stop valve for your kitchen sink. A consultation from a plumber or Ruhe Support professional will be ideal.

  • Shut Off The Main Water Supply And Drain Excess Pipe Water

Once you have purchased the correct fitting as per the size and the pipelines, the next thing you do is shut off the main supply of water in the pipes. This will prevent the wastage of water in case any damage or mishap takes place during the replacement process. After turning off the main supply of water, turn on your faucets and let the water already in the pipes drain off completely. This helps in avoiding spillage.

  • Remove The Faulty Valve

If your valve is threaded into the wall, all you have to do to remove it from the supply line is twist it. Where the valve body attaches to the pipe, fasten a pipe wrench to the flat sides. To release and take out, counterclockwise rotate the object.

  • Inspection Of The Exposed Supply Line

Once the old faulty valve is removed, carefully inspect the exposed supply line. You may want to make sure that it is not damaged or that it is the main cause of leakage. Ensure that the threads on the supply line are intact and are capable of supporting a new stop valve. Also make sure that you change the Teflon tape.

  • Fix The New Valve

Fix the new valve on the threads and connect the water pipes to the kitchen sink faucet. Make sure fitting is properly tightened and screwed and the flanges (in any) are rigidly fixed. Now turn on the main supply and check for any leakages. If there is any leakage then you need to tighten the valves using a wrench, if not then you are good to go!
