leaking valve
Posted by paul richards on April 13, 19100 at 09:08:54:
Oil forced hot water furnace. Over the furnace is the expansion tank which is threaded into a Taco air scoop. On top of the air scoop there is some sort of brass breather valve which, lately, has been leaking a good deal of water. It leaks worse when there is no heat being called for. When heat is circulating, very little water drips out.

any advice?
