    The last bay on passenger side has urine leaking into it. This coach has two vaccuflush toilets but no wet spots on floor. I've tightened everything that I can find. Any ideas?

    I just went through this with our 2016 Southwind.  My vacuflush bellows pump was leaking.    Don't know what if any maintenance had been done on the system before we bought it fifteen months ago, but we decided to replace the pump instead of rebuilding it.  Pricey, but I don't want to go through that again anytime soon!  Access was through a small hatch in the pass-through storage bay, and it was totally inadequate.  I ended up cutting access hatches through the bed and then the floor.  I'm sore, bruised and cut up but it's working fine.  I'm 72, so don't know if I could (or would!) do that job again in a few more years!

    Our last bay (by the rear bumper) on the passenger side had a leak, but it wasn't urine.  It was water coming in through the access panel between the bay and the diesel engine.  

    The vacuum pump should run for 60 seconds after you flush a toilet.  If your vacuflush toilet pump doesn't start running on it's own, and there is water in the toilet then you don't have a vacuum leak and that liquid in your rear bay isn't urine.  If the pump is running and one of your toilets is dry (no water) then you have a toilet seal issue.  and if there is water left in both toilets, and the pump runs without flushing the toilet, then there is a leak in one of your lines or in the bellows.   

    Just be sure that what you are calling a urine leak really is a leak from the toilet system..
