I cannot get hot water to the shower. The shower has a single water faucet and gets hot/cold supply, but the shower only gets luke warm. I have tried to adjust the handle control to no avail, any suggestions?

Please tell us the brand and the model number of your shower valve, it sounds like you have debris inside the valve or bad cartridge, Thanks.

I just had the same issue and it was the shower cartridge needed cleaning (sometimes they need to be replaced) but this would all depend on the brand and type of shower system it is.
