Help no hot water to my shower . I had well problems with a bad tank. I put a new tank in ,replaced the pressure switch, and the check valve. Now I have hot water in the kitchen and bathroom sinks but the hot water in my shower sucks . If I reset my tank pressure to 38lb and adjusted my pressure switch to 40-60 would that bring up the water pressure to circulate more hot water

Your problem isn't with your pump. It's your shower valve. Sounds like some trash got intro the cartridge and is now clogging the inlet ports.The solution would be to shut the water off and open up the valve. Remove the cartridge and clean the inlet ports. Now turn the water on for a few seconds to flush out the supplies. Reassemble and test/ Better now? Good luck, Tom
