 A water heater expansion tank is another small tank that is attached to the water supply pipe of the water heater. The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure.

This is how the top of a gas water heater, up to code, should look like. It has the expansion tank, vacuum relief valve, and proper venting. Newer water heaters have sensitive sensors that will shut off your gas water heater if there is not proper venting or ventilation space. 

2nd Floor Fees

2nd Floor Fees

Having a unit on the 2nd floor creates a greater liability during installation. The risks involved are much greater, and heavy work/lifting is required to complete the install. This is the reason for our added fee for any 2nd floor installations.
