Hi we have a new Motorhome from last year and the grey waste basically trickles out. The fresh water is fine, but the grey has done it from new so shouldn’t be dirty. Any ideas how to speed water coming out? Thanks
Pipe or drain tap is possibly blocked. My Elddis CV20 has a 28mm hose from the tank then it’s terminated in a 10mm drain tap . I changed it out last week to a 28mm drain tap which solved the issue with slow drain down on grey waste , but to note when I did change it there was a load of crap stuck in the rear of the tap which made it even worse.
