Shower leak is it possible from Moen diverter to shower head

Can you take a picture and post what you have?

You will have to replace the shower diverter button. Remove the handle, remove the faceplate, and the diverter will screw out. Any plumbing supply that carries Moen products will have a replacement button for your valve

a lot of shower diverters do this..you may need a bigger seal on the diverter..if you can remove the spout assembly from the tub(with the diverter valve in it) and take it all to the hardware store.. see if they have a different seal/diverter that has a snugger fit but still falls to drain the shower head line out..that will slow that leakage..the spout is on a pipe and unscrews counter clockwise(normally)unless its a single valve unit..with the wide ring around the back..then that calls for a plumber..

check or change diverter

remove cart. grease it up with plumbers grease check seals on cart.

Only two possibilities here the diverter tub spout is not open all the way to let water to the tub only or the shower valve is installed up-side-down.

Call Moen directly. They will ship what you need to your door, for free.

Not unless you had a backward plumber , If the diverter at the faucet is open for tub, then no water will go up the shower, The shower may hold enough water up there to make it look like a drip, Even if the valve was leaking all the time, it would not go up, it would come out the faucet. It only works with pressure. Unless the valve was plumbed wrong,,, Hope this helps.

sound's like you either have some debris caught up in there, or you might not have your handle on correctly. give that a try .

It sounds most likely to be a bad cartridge.

Hope this helps
