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.

Are you running a tankless or tank heater. If she took a shower and then you wanted one i'm not sure there is much hot water left unless she hopped in and then out.

It’s a 40gal tank. The sink next to it will run hot water while the shower stays cold. But in our other shower we can run my daughters baths and then both me and my wife take hot showers back to back to back and never run out of hot water.

when you removed the limit stop, the valve can turn to cold instead of hot
the limit stop ring has 3 numbers, 1,2,3 put the limit stop back in the valve set on 3
Well my wife got in and turned it up and it got hot and stayed hot and she wants it to burn her skin. (Not really but it’s stupid hot). But then I get in and it won’t even get lukewarm.

right here right now, over there later on.
with out the limit stop, the handle has no way of knowing what you want.

after you reinstall the limit stop. then we can determine if it might be the cartridge or not

you are asking me to tell you what is wrong with the truck. when you have the choke not hooked up
my answer is hell i dunno. put it back together and we can go from there

what model is the valve?

have you replaced the cartridge with the exact same one?
There are different cartridges. it needs to be the one for that valve
Yeah it’s just a price pfister mixing valve. I looked it over comparing for 5 minutes and made sure it was the same before putting the new one in. It did great for a few days after replacement but then all of a sudden lost pressure on the hot side. It got better so I thought it was just an air bubble or something. Now it just picks and chooses when it gets hot but the pressure is good
