Disappointed

FWIW, the "Kant Leak" valves are notorious for leaking - mostly at the "T" connection --- I have one on my 5th wheel that has been repaired and I also have a spare.  Earl indicated when I picked my unit up that their early valves gave them a problem as well, but the new ones are better --- we'll see!!

On our 2016 2351, we went thru two of the water selectors.  Bob told  us they were looking for better valves. Unknown if they changed brands or not. BUT, he told us to relieve all the pressure on the water inlet and water system  before turning the selector. I do this all the time and have not had any problems since. It appears the selector is different on our new 2552X.

There is some information in this thread about the 4 way valves that might be of interest.
