I agree with others that the joker valve has, at most, a one-year life span, and routinely replace it every year.

However, having suffered the same problem with my jabasco unit, now + 15 years old with several rebuilds, I bought the jabasco kit with a new 'locking' pump assembly. With it is in the locked position, where it stays unless used, no water can return from anywhere back to the bowl. Problem solved for about the cost of he usual rebuild kit cost and it hasn't returned in the 3-4 years since I replaced it. The bolts match exactly so you unbolt/unhose the old pump assy, pitch it, rebolt/rehose the new one in about 15 minutes.

In our case the water was backflowing from the discharge hose into the bowl. Our solution was to over pump for approx 20 seconds on wet flush before pumping on dry flush. That way the backflow would at least be cleaner water!

First few times this happened I chalked it up to a guest over-flushing, got it pumped and went on my way. The Jabsco head is 3 years old. The system was completely redone by previous owner. It was a very well done job, no mickey mouse stuff on the surface, all new hoses and recommissioned blackwater tank. I checked the Jabsco manual and all appears to be piped correctly. The last trip was the last straw. I had to go below every 10 minutes and scoop some very disgusting water out of the bowl and pour down sink drain otherwise it would have overflowed. After a couple of hours of this the shine wears off, believe me. So - my plan is to take out the pump/valve assembly and look for a failed seal. Should the head discharge hose-to-tank have a check valve in it? I think not because it would become fouled with solids. I'm aware of principles of siphoning but short of drawing a diagram I don't think siphoning is the problem. I can't think of anything besides a failed seal. Help!
