Is it normal for a water heater line to be hot?
A: It is normal for the incoming cold water pipe to get a little warm due to convection – that is, hot water rising in the tank. Also copper piping is a good conductor of heat. Many modern water heaters have built-in heat traps to limit the migration of hot water. However, hot water five feet back on the supply line is not normal.
What should I do if my water heater inlet is not working?
The inlet and outlet threads on your water heater are plastic. It’s a one time deal, you’ve got to do it right the first time. Wait until you need to replace the water heater. Use all copper next time.
