I need help. I have an RV that has been hooked up to a Septic tank. The holding tank is full and will not drain when I pull the valve release.
There are two other rvs connected to the line, Im closest to the septic and a good 3 feet above the ground down to the spetic.
Is there a reason why the holding tank would not drain? There is plenty of gravity.
As well for some reason my water supply will not allow outside water, I have to fill the holding tank to use water in the fucets and shower.
Could the pressure be too high for the intake.
I have a 2007 MaxLite BHS.
Everything worked fine at a regular camp site but when we hooked to a permentant site these things started happening.
Its sounds like your city water inlet.. check valve may need to be replaced...as for the tank not draining sounds like you got a major clog or maybe your gate valve is not opening...does the gray tank empty...have you been using chemicals in the black tank to break down the waste..
