Bailey Senator S6 grey water

[JON2515]

The washroom waste water pipe on my Senator Series 6 goes across the van uphill to the outlet making discharge slow or non-existent unless the van is parked higher on the nearside to give it some fall - Baileys Customer Services useless comment was that all Senators are like this - anybody suggest a solution?

Most grey outlets are fairly level and so can be slow. We had a senator that was fine until it was very cold and it froze. Equally the fitter might have put a loop on the shower drain. Have look. (Our coachman had one- easily solved.)
