Have a leak somewhere above my oil burner thats dripping down off the expansion tank. As far as I can tell its from the newer looking gizmo thing in the pic. What is this? Some kind of pressure release? Easily replaced or need to pay someone?

| Yes, it's job is to release air in the system but keep the water in. After awhile they become corroded and let the water out. There is a float inside that opens and closes a bleed valve. If you have a new one on hand, most times you can change them out quickly without to much mess. The systems that I have worked on have a fill valve fed from your house's main water supply that may or may not need to be opened to refill the lost water/antifreeze in your heating system. |
