Hello Ladies and Gentlemen: February 23, 2009

I am a new member, and I am looking forward to learning from you.

We have a Moen tub/shower control valve. It has a single-handle type of rotary knob. If it is pulled or pushed, then the water is on or off. If it is rotated, the water temperature is controlled. The same unit (under the rotary knob, covered by the same face plate) has a push-button diverter. If it is pushed, the water is diverted to the shower. If it is pulled, the water flows through the tub-spout.

The diverter does not work well, and water flows through the shower AND to the tub as well.
Lubrication with WD-40 did not help.

How can it be repaired? Is it necessary (worst case) to replace the entire unit?

Many thanks and regards,
sesebo2004

You have to remove the handle and faceplate of shower body and you will see were the diverter is screwed in just unscrew it and replace you can purchase the diverter from home depot or any local plumbing supply store . Just make sure the water is off before doing this

I have the same problem. But... Beware if it is leaking into your tub, it is also leaking into the wall. Mine is quite old and the only diverter pin replacements I am finding on line are 1394 & 1198. The have an extended brass piece just below the part you tighten so it doesn't look the same as the one I pulled out..
