Frequently Asked Questions

How Do You Change A Zone Valve On A Boiler?

The process of changing a zone valve on a boiler can vary depending on the make and model of the boiler in question, as well as the specific type of zone valve in use. However, in general, the process will involve shutting off the boiler’s fuel supply, shutting off the water supply to the boiler, and then loosening and removing the old zone valve. Next, you will need to install the new zone valve and reattach the water supply and fuel supply lines. Finally, you will need to turn on the water and fuel supplies and test the new zone valve for proper operation.
