I live in a rental house and cannot get hot water to the shower. The tub has separate water faucets and gets hot/cold, but the shower might get luke warm. I have tried to adjust the handle control to no avail, please help

Is this what you're looking for? (see image) If not let me know. Good luck, Tom

Good Morning, I resently which the shower head in our bathroom. And notice about a month later that we aren't able to switch from shower to bath. It seems as if #14 will not stay in pushing for the water to flow to the tube facuet. However, while shower #14 squirts water the entire shower. What do I need to do?

Replace #14... the diverter. Basically, using a faucet valve wrench or pair of pliers you spin the old out and install the new diverter.

Take the old diverter out and bring it to a plumbing supply house... they should have a replacement in stock... ;)
