If the alarm line is passing water and the alarm valve is not open, the clapper is not seated. The only time water enters the alarm line port is when the clapper is up, or not seated. Take off the cover, lift up the clapper and look at the seat(s) and the rubber gasket on the clapper. You might have to hand cut a replacement. It's probably cut, warped or damaged. Tom GRS
Am I allowed to respond to my own question? The alarm valve leakage resulted in the drain pipe from the water motor gong filling with rust. I suspect that the water flowing through the retard chamber may have caused the rust hole to form in the retard chamber. We now have a new retard chamber, new restriction device, new water motor gong, new drain pipe. We still have water trickling through the restriction and out the drain pipe. At present I have the alarm valve closed, so we have no leakage, but we also have no alarm notification. Any ideas how to fix this problem? We have an old Star 4-175-D wet valve that is leaking through the alarm valve. when the valve is open, we get a trickle of water into the water motor gong. Not enough flow to trip the gong, but enough to rust the pipe shut. I do not find any info on this valve on the Tyco web site. Does someone have a tech sheet you could send to me?
