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?
