Why are both pipes on my water heater 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.
What is the pipe on the side of my hot water heater?
Since the condensate overflow pipe for air conditioners looks similar, the vertical pipe on water heaters is often confused for an overflow pipe. However, this pipe is actually what’s known as a temperature and pressure relief valve drain pipe.

The two most common drain pipes that most people have on the side of their house are: Air conditioner condensate lines (AC drain line). Water heater pressure relief valve lines (PRV drain line).
Does a hot water heater have a drain pipe?
Normally, a pipe attached to the water heater drain pipe is a recirculation line. While not absolutely necessary, a recirculation line keeps water in the pipe hot and reduces the amount of water wasted before you get hot water. The pipe could also be for a pressure relief line.
Can hot and cold water lines touch?

When hot water comes out of the cold tap?
If you notice hot water coming out of the cold tap, it could be due to how your piping is situated. If your hot and cold-water pipes run parallel to one another up to the sink faucet, they can impact the temperature in the opposite pipe. This means that the hot water may feel colder and the cold water may feel hotter.
Why am I not getting hot water out of my faucet?
A likely explanation is that your faucet might be clogged. Over time, mineral deposits build up inside the plumbing fixtures after repeated use. This blockage doesn’t allow the hot water to flow correctly. The problem becomes more prominent when combined with other plumbing issues, such as low water pressure.
What to do if pipes freeze?
Running water through the pipe, as cold as it is, will help melt ice in the pipe.
