I had bought the tap to prevent the return of the water from the long gooseneck of the toilet flush back into the toilet with a not always tight valve in the toilet. I have 2 cocks installed at 2 toilets. The one closes quite reliably, the other licks regularly - after some time the Klobecken again full of the water from the hose - Swaps at sea speed - missed and therefore disappointing
I had a very serious problem on this 2 inch trudesign. The valve is leaking water from the ball maintenance ring. It's absurd because now I have to haul the boat out for this replacement. Svb has taken over their business by sending a new valve but I am still entirely responsible for the hauling cost
