THETFORD PORTA POTTI BENCH TYPE WILL NOT FLUSH?
I have a Hobby caravan with a Thetford bench type porta potti fitted but it will not flush I know I have power and the pump works because last year I left my toilet bag on top of the flush switch and after a while it started to flush. I removed the bag and it stopped.
But it would not start again any idea whats wrong
