Why do you need an Expansion Tank?

The expansion tank serves as a backup system to prevent overworking your plumbing. Instead of causing too much pressure on the plumbing, caused by an excess amount of water, it rushes into the expansion tank and lowers the pressure in the water heater to safer levels. This ultimately protects it from damage.

Ensure the expansion tank is placed above the water heater. This prevents water pressure from damaging the pipe located in the water heater. Always have an expansion tank installed on top of your hot water tank by an experienced Sydney Plumbing expert to prevent overworking it. The expansion Tank is designed to hold a certain amount of liquid, so it is important that you find out how much you need in order to prevent flooding.
