Had one slight problem on our trip.The black water was 1/3 full,grey about 3/4 full and water tank 1/2 full.Pump running but no pressure,dumped the grey and black tanks and pump ran fine,was that a fail safe occurence when grey tank was close to full?
John,
I've never heard of a fail safe like that. My pump will gladly keep pumping water into the gray tank no matter how full. Might want to check your wiring on your latching relay. I found my quick connects were lose. Used a pair of pliers to remove then crimp tighter.
see ya

Not sure I would trust the gauges. I don't, but want to.
But fresh water is about 100 when full.
Grey water 3/4 full might be .75 of 112(?) or about 78 gallons.
Black water 1/3 full might be. .33 of 54, or about 18 gallons.
78 + 18 + 96 gallons.
Seems about correct on the quick figuring. Something strange was happening.
Sounds like the fill switch might be on, with the pump on, in our coach we would have no pressure and pump running. Guests are the usual culprits that hit the switch in the bath near the lights and the pump runs. Forever with no pressure. See latching switch or search water fill, maybe. Good luck!
The amount of water in the grey and black tanks should have nothing to do with the pump running and no pressure. Your coach is the same year as mine, usually when the pump is running and no or very little pressure the fill valve under the bath sink is open. After dumping did you add water to the fresh tank and maybe close the fill valve, or someone else close that valve? With the pump on and the fill valve open, the pump pulls water from the tank and pumps it back into the tank.
Whatever is was it's cured now and running good.I think the open and closed valve was the problem.Thanks for all the replies.
