Hope someone has some suggestions on this: I have two
electric Raritan heads, one in VIP and one in Master SR. When the VIP is flushed, it sounds like it pressurizes and whistles/squeals for about 10 seconds after
flushing; almost sounds like the line is pressurizing, but the bowl flushes and empties without hesitation. I would suspect the vent system except that the Master does not do this. No smell, no
leaks, empty
holding tank. It sounds like its coming from the vented loop; is this possible? Any Ideas?
