We had a contractor completely renovate our home recently and the hot water pressure is very low in our master shower. The rest of the sinks and showers are fine, just this one is giving us trouble. I have read other questions on this site and followed the direction of the answers and I still can not get this problem solved.
I have taken off the valve behind the handle, this did not help. I took the entire shower head off so there was only the pipe sticking out and it still has low pressure, only on the hot water side. Is there anything else I can do? I would call our contractor for help but he is MIA...
Thank you so much for your time.

My guess would be that you have something in the hot water side of you faucet, if you know how you could cut off your water and see if you can find a blockage in the faucet. If you have someone to help you could hold something in front of the faucet while you have it apart and have them turn on the water for a couple of seconds. Be prepared for lots of water. And only a couple off seconds.
