Hagerstown Plumbing Question: Why Does My Tub Faucet Leak when the Shower Is On?
Here is a common and yet seemingly complex problem you can have with your Hagerstown plumbing. You turn on your shower, flip the switch to go from tub faucet to shower head and the tub faucet continues to leak. Not only is it rather irritating, but it draws from the water pressure in the shower head. Let’s take a look at why this happens and how to quickly fix it.
Why the Leak?
There is a valve in your tub’s faucet that diverts water from the tub to the shower head when the switch or lever is pulled to turn on your shower. Because the valve is not a perfect seal, the tub faucet will drip a small amount during a shower. However, if a large amount of water is coming out of the tub faucet and very little is coming from your shower head, it is likely a problem with that valve.
In some cases, the only way to know the root of the problem is to take apart the assembly and check all of the valve parts individually for damage. The specifics of the repair process will depend largely on the type of shower and diverter valve you have.
Fixing the Problem
To fix this problem, a plumber can either replace part of or the entire shower diverter valve. They start by removing the faucet and pulling the screw that holds the shower diverter valve in place. Once the screw is removed, they take out the rubber washer and replace it. Many times, this is enough to fix the problem.
If it is not, however, you may need to have the entire shower diverter valve replaced. There are some situations that make it hard to reach the shower diverter valve, such as when you have a shower handle instead of a faucet knob. If this is the case, you may need special tools or professional assistance in removing the knob to access the valve.
