How to Install a New Hot Water Heater
You have likely already read our blog on how to remove a hot water heater so now we will discuss how to install your new hot water heater. When purchasing a new tank be sure to use something similar to the pre-existing tank as far as being an electric or gas tank.
- Start by positioning the new tank in the area where it will rest. Maneuver the tank to an orientation where all the wiring and pipes can easily be attached. Also keep in mind that the tank has cover plates that need to be accessible during any future maintenance so keep these visible.
- Wrap any threaded pipe fittings with two or three layers of teflon plumbers’ tape then re-install the water pipes. When applying the tape, start at about 1" from the end of the fitting and wrap the tape in a clockwise manner around the pipe, overlapping at least 1/2 with each rotation. The entire threaded area of the pipe should be covered with two layers of tape.
- Connect and tighten all pipes with a wrench. (DO not over tighten).
- Turn on the water and check for any leaks. Wipe all joints dry and check again after several minutes for any leaks. To eliminate air in the tank and plumbing allow the hot water tap to run until it stops sputtering.
- When the tank is filled turn on the power (if electric) or connect the gas supply line (if gas). Test the gas line for leaks. Recommended temperature is 120 degrees Fahrenheit. This will take several hours to reach.
