Ok, guys my shower chooses when to get hot. I’ve replaced everything from the mixing valve to the shower head. It’s a price pfister single handle and the anti scald ring is removed for now because I cannot get hot water all of the time on demand. It got hot for my wife to take a shower tonight. She turned the water off, stepped out and I came in literally 2 minutes after and it will not get even lukewarm. She had the whole place steaming. Sink next to it will get hot in seconds. I’m at a total loss.
