Why does water come out of tub faucet when shower is on?
A leaky shower diverter. A diverter may be an unfamiliar term. The diverter is a valve in your tub’s faucet that diverts water from the tub to the showerhead when the lever is pulled to turn on the shower. A small amount of water dripping out of your tub’s faucet is normal because the valve doesn’t have a perfect seal.
Why does water come out of my Tub when I Turn on the shower?
Most likely the problem is just the diverter on your tub spout, it’s probably not opening all the way, which allows some back pressure to build up in the pipe that eventually gets back up to the shower head. It could also be corrosion inside of the pipe that is having the same effect.
When does water come out of the shower head?
When the water is coming out the fastest (mixing hot/cold) water comes out of the shower head. The person (not me) I had helping installed the valve at about 48″ from tub floor or about 30″ above faucet. The directions clearly stated the valve can’t be more than 11″ above the faucet.
What happens if you don’t replace your shower faucet?
If this is the case and the faucet isn’t replaced, it could cause water to leak out on the wall behind the shower, which could cause rot, mold, or mildew. If corrosion or a broken washer is the cause of your diverter woes, you’ll probably need to replace the diverter valve. Not sure how to do that? Not to worry!
Why does my shower head back up when the tub is on?
If you mounted the shower head lower than recommended, or vice-versa, mounted the valve/tub spout higher, that could be a problem. Restrictions in the faucet supply tubing, as spacechallenged wrote, can be factor. If there is a restriction in the faucet plumbing then the water can back up and exit the shower head.
