Forum Title: strange leak
We have a shower with a single valve and just one outlet (the shower head). No tub, no tub spout. Just a shower with a single valve handle. When we open any other hot water valves at the sink, washing machine, etc. water leaks form the shower head. With the valve closed, I don't understand how this is possible. I don't think there is a hot water return. We do have one in another area of the house.

It's a Kohler. Not sure what mode number but here are some pics. Looks like model K-304-K

may just be the vibration of the system jiggling the pipes and shaking out a little captured water in the head. I sometime have to remove heads after a repair because they drip for awhile and I can't tell if my repair was good with them still in place. Remove the shower head to test to see if it still leaks when other fixtures are used. Replace the cartridge assembly. I would presume you did if you disassembled it for the photo.
