Hot Water Heater Expansion Tank Installation

The Hot Water Heater Expansion Tank Installation procedure involves placing the expansion tank on the cold or hot side of the water heater. The location of the expansion tank depends on the local codes. Pipe wrenches and Channellock pliers are required for this installation. Galvanized* fittings are recommended for the job as they are cheap and easy to install. They will also protect your pipes and fittings from corrosion.

The first step is to attach the copper flex pipe to the dielectric union of the water heater. The pipe must be short enough so that it can be twisted and looped around the tank. The outlet should point upwards and away from the expansion tank. It is important to ensure a tight connection between the pipe and the expansion tank. Afterward, connect the tee fitting to the expansion tank and screw it into the elbow.

The next step is to attach the tee and the expansion tank. The tee should be attached to the tank with a female threaded adapter. Use a plumber’s tape or pipe joint compound to seal the connections. The tee outlet should point up and the expansion tank should be at least 18 inches above the water heater. Avoid installing the expansion tank with a copper pipe sticking straight up in the air as it may snap and flood the basement. Lastly, use a universal mounting system to attach the tank to the water heater.

To install the expansion tank, connect the water supply line to the inlet pipe of the water heater. Then, install the tee fitting and the expansion tank using the pipe wrench. Before installing the tank, use pipe joint compound and Teflon tape on both ends to prevent leaks. If you are planning to use the expansion in a kitchen or bathroom, apply a coat of Teflon tape on the connecting pipes.

Before attempting the Hot Water Heater Expansion Tank Installation, you must make sure that the expansion tank has enough space for the tank to expand and fit inside the water heater. The tank should be at least one foot above the water heater. The longer flex line should be angled away from the expansion tank. It should be tightened into the elbow with pipe joint compound or plumber’s tape. Once the connection is tight, it is ready to be connected.

Before connecting the water supply line to the expansion tank, make sure that the water pressure in the expansion tank is equal to the pressure in the water. If the pressure is too high, the tank could rupture and the water heater may not function correctly. It should be at least 18 inches away from the heating element. After completing the installation process, the water heater should be level with the expansion tank. After installing the expansion tanks, you should test the temperature and pressure of the water in the water supply system to check whether it is working properly.

Before completing the Hot Water Heater Expansion Tank Installation, you should make sure that the expansion tank is fixed near the water heater. The tank can be located anywhere along the water supply line, as long as it is near the water heater. While some manufacturers recommend that the expansion tank be installed in a vertical position, any upright position is fine. Then, you should connect the expansion to the inlet pipe.

Afterward, you should connect the water supply line to the expansion tank with the help of the PEX pipe. After that, you should connect the expansion tank with the tee to the water heater by one foot and at least 18 inches. Some plumbers connect the expansion tank to a copper pipe that sticks straight up in the air. This type of connection is dangerous because it can break and flood the basement.
