Earlier this week, we talked about plumbing fixtures that can be shut off using a shutoff valve in case of emergency or for a repair. Today we are going to finish this discussion by looking at the types of valves you may encounter and how to shut off each type. Shutting off the valve properly will allow you to stop water from flowing to the fixture and therefore make it possible to repair any problems that fixture may be having. Forgetting this step will make quite a big mess should you try to perform the repair with water still flowing to the fixture. This is what you are looking for:
- Ball Valves: Ball valves are so named because they use a ball to block or allow water through a pipe leading to a fixture. They will either have a lever or an oval shaped knob that can be turned. When the water flow is open the lever or knob will be parallel with the pipe it is feeding water to. To turn the water off, simply turn the knob or lever 90 degrees to the right so that it is now perpendicular with the pipe line leading into the fixture. These valves are typically found under sinks, but they can also be found behind toilets and even on the meter.
- Gate Valves: A gate valve will open and close a water line by opening and closing a gate or wedge. These valves look like the typical valve you would find on an outdoor spigot. To close a gate valve you will turn the knob clockwise towards the right until it can no longer turn. To turn it back on simply turn the knob back counterclockwise to the left. These are usually found on hot water tanks, toilets, and the main water line.
Play it Safe and Call a Pro!
If you can?t find a valve on a fixture, contact a plumber. Many will be happy to help you find your shutoffs especially if you are having them out for service. If you are ever unsure about what you are doing or what valve you should be turning, play it safe and leave it to a professional. They will have the know-how to safely repair your plumbing system.
