Went to connect a customers new washing machine… a crappy Bush!
Draining very very slowly. Whipped the drain hose off the drain stub.
Looking down the drain hose there is what appears to be a non-return valve wedged in the hose about a couple of inches down.
This seems to fill most of the hose, only allowing the water to escape through the small gap surrounding the ‘valve’
Never came across this stupid device before. (the rubber flap valves were bad enough. this is worse!)
Anyone else found this?
