Hello all,
I'm reasonably sure I have a black tank flush line leak from the vacuum checker/backflush valve. After reviewing the other posts addressing these valves,
in the case of the 373FB, the valve should be located by the shower controls. The issue I have is the area has no access panel, just the full wall panel to access to plumbing.
Has anyone had the need to replace the valve on a 373FB and am I correct in the location?
Thanks in advance,
John B
