An overflow tank is an essential part of any water heating system. These tanks collect excess water that is released from the heat exchanger during normal operation. The water in the overflow tank is trapped until it reaches a preset level, at which time it is released into the drainage system.

Overflowing water can cause serious property damage if left unchecked. Homeowners should regularly check their overflow tanks for blockages and leaks and make necessary repairs or modifications as needed. Overflow tanks should also be cleaned on a regular basis to prevent Build-Up of sediment and other debris that can clog the tank’s filters and reduce water flow. follow these simple steps:

2) Disconnect the overflows hoses: If you don’t have an automatic sprinkler system, you’ll need to disconnect the overflows hoses before proceeding.

3) Remove the overflow tank cover: To access the overflow tank, loosen the screws that hold the cover in place and remove it. Be sure to replace these screws when you replace the cover.
