Do you need to drain a copper water heater?
Depending on the location of the leak, you may want to drain the tank, although most flexible copper tubing on a water heater is going to be at the supply lines on the top of the water heater, in which case it is not necessary to drain the tank. The flexible tubing on the water heater is secured with screw on couplings.
Why is my water heater supply line hot?
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.
Why is my hot water heater leaking cold water?
Cold water lines will sweat during hot humid conditions. At times this water may run down the pipe and puddle up on the top of the tank. Before you assume that you have a leak, dry off the pipes and try to determine where the water is coming from.
Why are there pinholes in my copper pipes?
The #1 reason why copper pipes leak is due to turbulence. Turbulence enters your system in 2 ways: Velocity: Plumbing code limits the velocity within your piping system to 8 fps (feet per second) for cold water and 5 fps for hot water. Limiting the velocity reduces the turbulence in the pipes that creates pinholes.
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.
Where does the water line connect to a water heater?
Once inside, the water main line runs directly to your water heater. Just before connecting with the water heater, however, your main line splits into two different pipe paths. These paths are called the hot and cold service lines.

Why does hot water go through copper pipes?
In an effort to ensure instantaneous delivery of hot water, an oversized pump has been installed, with the result that the pipes are literally eroded away by their own contents. When water flows through a copper pipe, dissolved oxygen reacts with the copper to form a protective oxide coating.
