circulator problem

in THE MAIN WALL
I have several of these installed, they have been no problem.
I used to use the B+G isolation/check valve flanges, no more though. I had two call backs for no heat due to sticking checks in these flanges.
Both where the result of floating rectoseal pipe dope in system. The contamination was not big globs believe me, it was almost invisible. The problem with these flanges is the check cannot be serviced with out disassembly and draining.

The Taco IFC can be serviced after removing the cartrige.

There was an error rendering this rich post.

    To answer your question

    No, I'm qereous why your bioler pressure was at sixty pounds though, that is up with that?

    So far

    the only IFC I have seen stuck was when someone tried to backfeed a heating loop with 30 psi can hardly blame the check.

    Was the circulator on return?

    Some times when purging the system with the pump on the return, and the purge valve after the circulator it is possible to fill the system with city water pressure, because the flow can not go through the pump. For your reference I have attached a recommended piping diagram for IFC pumps.
