I used to have hot water ok in all the showers and faucets. After the past winter, I have not got hot water in one of the showers upstairs. Everywhere else are OK except that. We use GAS Heat with a traditional Hot Water Heater. Could someone explain why? Thanks
Shut off the water supply DISASSEMBLE the hot water spindle and check for a broken washer blocking the opening and flush out the H/W side and replace the washer Good luck
