Backstory: I've got a vacuflush system on my 2017 Fleetwood Pace Arrow 36U. The pump began to run continuously. Not too uncommon, and it's always been a small piece or tissue or something caught in the gasket seal right at the location that opens when you hit the foot pedal (not sure what that is called). This time that seal was fine ( I could tell because it wasn't sucking water through). After some research I learned it was probably something in the duck bill valve on the pump. (symptom included clogged toilets and continuous running vacuflush pump) Dug into the system and YES>>>>> that was it.... cleared and cleaned the blockage. Pump and system worked fine for about a day then begins to stay on all the time. Symptoms were slightly different as the pump would stay on but drain slowly. Would not drain if I turned pump off. I figured it could not be the same issue, blockage, because no solids had been put into the system since I cleaned it the day prior. Just prior to breaking the system apart again to see if I could find the problem I ran the pump to drain all the water out for less of a mess when I disconnected everything below. Well, bad news.... the pump stopped.... but not because it had achieved the desired pressure.... the toilets would not drain, and the pump would not run. I pulled the system apart and sure enough, no clog. No obvious reason it would not keep pressure. I thought it might be a duck bill valve damaged slightly and not obvious to the eyes.... I cleaned everything up, cycled the pump by hand to simply check to see if it was frozen up, or binded somehow.... It cycled manually just fine.... but would not cycle when turned on. You could hear it make a small noise when the switch was turned on, but would not cycle. Since the system really won't drain without the pump I bypassed the entire system and am now on gravity drain, which doesn't work very well, and obviously we can put solids in there. The pump I have is: Dometic Vacuflush (pictured below). I guess at this point I'm looking for any ideas I may have missed that are obvious? or.... if anyone knows a place that can work on this pump in the Clermont FL (S.E. Orlando) area I can bring the pump in. It's not hooked up so it would be easy to do. OR..... IS THERE A WAY TO PERMENANTLY BYPASS THIS CRAPPY SYSTEM???? My friend has a 3" pipe that goes directly into the black tank from his toilet. I would love that!!!!! The hoses on the vacuflush are as small as 1" near the pump..... a recipe for clogs if I've every seen one. I can't keep it bypassed like I have it now because of the small hose, and how it has to go down, then back up..... the pump is what pushes the contents back up a foot or so to get into the top of the tank. Right now we are at Winter Quarters Manatee Encore park near Tampa but moving up near Orlando Thursday Dec 21. Dometic Vacuflush 12VDC LPVG-W-PUMP Assembly
FMCA Community Members, I'm seeking recommendations for what others here feel is the best liquid chemical treatment product(s) to use for periodic treatment of their sewage tank (i.e. black water). My coach is equipped with both Dometic macerator toilets and a Thetford Sanicon system therefore, the use of dissolving tablet type treatment pods is not recommended.
