The shower in my master bedroom stopped having good pressure recently (luckily I was done), so we stopped using it and have just been using the guest shower. I finally got around to trying to fix it and hit a wall.
-I've cleaned the head and have even swapped it out with my other functioning shower head and same problem.
-Changed out the cartridge and the valve stem assembly with no resolve.
I researched the issue online and got the idea to check if there was any hot water coming out. I let it run for several minutes and I confirmed that there is no hot water coming out of the shower what so ever. Every other faucet/shower works in the house with no problems so I feel good about the water heater. Its a single handle turn counter clock (no pull) price fister. The house was built in 2004. Is there anything else to check out without tearing a hole in the wall?
