When I turn hot water knob on in bathtub water comes out of both hot water knob & faucet How do I fix it?
no problem with shower head
You need to pull the faucet out! If you don't know how to do that, call a plumber. Don't wait, because, you're probably leaking water, behind the wall, and could severely damage your house
Call a plumber
A new knob will help
The rubber washer inside the knob is most likely worn. If you replace it that will most likely fix the problem. You can get them at the hardware store.
Replace the O-Ring
