Water Heater Installation Mistakes that Should be Avoided


Seek help from professionals when installing a water heater in your house as much as possible. Doing it alone without any experience or knowledge in setting up this equipment will only result in a poor installation. This will article will just serve as a general knowledge and doesn’t encourage anyone with no plumbing or water heater know-how to install a water heater on their own.

Soldering Pipes Close to the Tank

Soldering pipes is needed in order to link the tank system with the water line of the house. However, soldering near the tank can actually cause damage to the water heater. This is due to the fact that important plastic components of the tank may be destroyed by the heat of the soldering process. When connecting the tank to a pipeline, soldering should be far as possible from the tank system.

Not Properly Checking/Installing the Temperature and Pressure Relief (T&P) Valve

These are crucial components of the heating equipment that help safeguard both the water heater and the user. The T&P valve acts as a safety feature by releasing water from its valve in case the water heater is unable to take in the high temperature and pressure. Without the T&P valve to release water, the water heater will definitely explode in the event of a pressure and temperature spike. Even if the T&P valve is properly installed, it should still be checked occasionally to make sure there is nothing wrong with the mechanism. After all, as an important part of the water heater, the valve should be fully functional at all times.

Not Making Sure the Metals are Compatible with Each Other

Most people don’t know that the metal composition of the pipes can actually affect the whole plumbing system. You see, there are certain metals that are compatible while there are others that become a total disaster when paired. For example: copper pipes in your water line are compatible with copper or brass connectors of a water heater tank. But metals like galvanised steel are not suitable with most metals out there. If you do have galvanised pipes, you need to install a dielectric union fitting between the galvanised metal and the other one.

Not filling up the tank with water before turning the heater on

This is one of the most common mistakes in water heater installation. If the tank is not filled with water, the heating system can be easily damaged, whether it’s powered by electricity or gas. With electric water heaters, the filament (conducting wire) can be destroyed while gas water heaters might crack. This isn’t strictly part of the installation but this process is an integral part of keeping the water heater functional for future uses.

Not Installing Security Features

Little do people know that water heaters actually need some security features to keep the equipment and your household safe. A good example would be earthquake-prone areas; if a water heater is always rocking due to earthquakes, chances are it will fall and possibly be broken. To stop this from happening you need to place a strap on the water heater.
