Hi everyone, this is my first post so please help me. My wife and i have been living in our current home for 2 years now. We have used everything in the house with the exception of the guest shower. We recently had a baby and we wanted to bath her in it. Well when we turned on the shower it turns out that no hot water comes out. Water stops when the knob is turned at around 1/4 towards reaching the hottest level.We left it running for 10 minutes and still no warm water. Its all cold!!!! Its weird because i then turn on the faucet in the same bathroom and hot water comes out so as in the rest of the house. Just not in the shower. What can be wrong??? Please help.
