Having problems flushing the vacuflush head on our 39 dancer, 05 model. Worked perfectly for a while and then started refusing to flush. Green (has vacuum) light stays on when this happens. Managed to clear it a few times, by repeated plunging etc and all appeared to be good, but then it plugged again, despite no solids having been flushed. The immediate prior flush "test" was just water and it flushed with gusto! Next flush was just" liquid" and a bit of paper - and nothing! Vacuum pump is not running and green light stays on. When the head was working properly, it only took may be 20 seconds to restore the green vacuum light, so the pump appears to be working as it should. So far, repeated plunging refuses to clear it.
I would assume the I just have to continue working on clearing the clog except for one thing. Each time I have pumped out the head tank, (we have only owned the boat for a few months) it seems like very little "material" has been removed from the tank. The tank looks like it is a two piece tank, nothing like the rectangular box tank on my previous boat. So I am wondering if I have an internal plug in the tank which is causing the problem.
I do not know how full the holding tank is, as I cannot see through the stained plastic tank sides and the three level probes do not register anything. (Separate question, how do I get these to read? The probes appear to be glued in to the tank). But we pumped out the tank again after this problem occurred yesterday, and again little material was removed, implying that the tank is empty. Inserting a hose in to the pump out vent enables a few gallons of water to be back added to the tank, without any problem - and then pumped out again - also without problem. I saw no signs of a leak when doing any of this - ie. we do not appear to be losing suction on the pump-out hose pipe.
Any help or advice on this issue would be very much appreciated as my wife is really "peed off" with this problem (pardon my pun!)
