Kohler shower diverter leaks (behind the wall)

This shower diverter is approx 35 years old. It is the pull type mounted to the wall above the tub faucet. Is it able to be removed (without damaging tile) and is there replaceable washers in it?

How would we stop it from leaking (both behind the wall and dripping out from the pull knob?

    Thanks mrrevol, I was able to remove the cartridge and replace the washers. This stopped the leak out the front of the diverter but did not stop the leak behind the wall (very slow drips) can be seen from a hatch in the first story ceiling.

    btw, we can not gain access from behind as another shower is backed up to this plumbing wall.

    Weird, when I removed the tub spout the leak seemed to stop behind the wall. I replaced the spout without the trim piece and could not see or feel any water running back into the wall on the galvanized pipe nipple, but the leak was back. I then put a temporary cap on the spout nipple... leak stopped again. I would have thought under pressure we would have had a bigger leak. Not so.

    I think I'll give up and just replace the entire valve set.

If you have a closet behind the shower or a wall you may be able to get to the diverter without damage to the tile ,are you sure you can't just change the cartridge? most times this is all that is needed to fix a problem like yours.

My tub faucet keeps leaking when the shower head is engaged. How do I fix it?


Depends on where the diverter valve is on the tub. If you pull up on a knob on the water spout for the tub, then it's not likely the leak will ever stop completely. If the diverter valve is in the wall then a repair kit can be had at any home improvement store.

I changed out my Kohler shower diverter cartridge because it was leaking after doing so when you open any faucet in the house it will leak the more faucet you turn on the faster it leaks. The lady plumber...


did your old diverter have a shut off knob on it? if so you may have not noticed it leaking, -what causes that is the existing shower faucet may have been mounted to high from the spout below -or the pipe going down from existing fixture to the tub faucet spout pipe may not be at least 3/4", -if its 1/2" it will always do that

Kohler rite temp with diverter. When the tub is turned on water leaks out the shower head. Changed the diverter didn't fix problem.


You could have a restriction in the tub spout or just too much pressure. Diverter only restricts flow to tub spout so any restrictions to the tub spout will cause water to go up to shower head.

My moen tub faucent leaks when i have t shower head on


If you are saying that water is still coming out of the tub spout while the shower is on that is not a big deal a rather normal. If it bothers you a lot then you will need to replace the tub spout as the diverter in the spout has gone bad or is going bad.

Now if you are saying that the shower is leaking behind the wall when the shower head is being used then the threaded joint at the shower head arm is leaking and will need to be undone and put new pipe dope on the threads and reinstall it or it may be just lose and if that is the case remove it and reinstall it anyway.

If the water is leaking behind the wall and the above is not the case you will need to get into the wall and see where the leak is coming from and take the necessary steps to fix it.

Hope this helps and good luck.

Leaky Tub Faucet (Antique Reproduction)


sometimes check the faucet screws they come loose or if they are old you might want to replace the whole diverter, take them to lowes or home depot and have them guys in the plumbing department hook you up. trust me you are opening a can of worms with rubber valve seats just get new ones. Make sure before pulling you cut off water supply to them.

Replaced shower valve. still drips from tub spout


The cartridge has 2 or 3 o-ring type seals around it that feed the water through, it picks up both hot and cold and mixes them. Some cartridges are replaced as one, some you have to replace the seals, just take the faucet info to the hardware store and match it up. I think the diverter is for the shower. It sends the water up instead of out.

I have an old home with a one hand Temptrol shower diverter which no longer regulates H2O temp properly. I purchased a Delta Carlisle 174939-SS-I and need to know how best to install this unit. I am a 60...


Start by turning the water off to the whole house. Open the tiled wall or if there is access behind the old valve open that wall instead. With a tubing cutter cut the hot and cold water lines as well as the shower riser. Remove any clips that are securing the valve to the wooden studs. Mount the new valve in the same area as the old. Make sure that the valve is not upside down arrows on the brass body will indicate flow direction for the tub spout. Connect the water supply lines to the new valve by means of soldering or mechanical joint. Connect the existing shower riser by means of soldering or mecnaical joint. Turn the water on and test for leaks.

Water sprays out the diverter


Remove hot/cold button in handle, remove screw/pull off handle. Remove the two screws in the wall plate/remove plate. Use a wrench to remove the diverter assembly. Get new diverter assy and reinstall eveything. You don't need to turn off the water.

My 3 handle bathtub fauset [price pfisher] cycles hot and cold


You will need to either replace center "shower diverter"assembly or a quicker fix would be to remove old tub water fill spout and replace with a "pull up diverter knob" type water spout. Cost about 10 dollars Hdepot Pull Knob to divert water to shower when showering.

Kohler KT12007 Showerhead


The device which directs the water up or down is called the diverter. Your diverter is not fully up or fully down. Rather forcefully push and pull the diverter a few times and your problem may be solved. good luck.
