The tenants complaint is that they are not getting hot water in the master bathroom shower and they run out of hot water in the hall bathroom tub in a few minutes I tested the system and found that the master bathroom shower the handle was only going to the warm position I removed the handle and found the limiter had not been adjusted I then checked the guest bathroom tu and it had hot water for about 5mins Then went cold I checked the water heater and found it is a gas water heater it is a 2023 model the heater is functioning as it should I noticed the expansion tank and shut off were installed on the hot side nipple of the heater when I touched the pipe it is ice cold and when I touched the cold side it was warm The water heater was piped incorrectly I have already adjusted the shower limiter I removed and swapped the dielectric nipples in the water heater Tested with no issues Job completed No new estimates needed No vis Clean out
