Lessons learned:

"Manabloc" leak....
Recently had to repair a "leak" on my Harney Manabloc.
The previous owner was having memory issues and unable to properly maintain nor drive the coach.
He stated he just installed a new Manabloc, but that it leaked like a fountain.
Opened ALL the connectors and found NO GASKETS (i.e. fountain).
A package of 1/2" beveled, rubber washers, a "uni-bit" & cordless drill, patience, and "POOF"!
18 months and counting.
Lesson learned.

On our Harney Renegade, I would have 3-6 valves go bad each year. I have sold the RV or I would post a picture, but I assembled a new manifold using 1/2Ē copper and ball valves. Never had anymore problems.

For future reference, the proper cone washers are available ready made at any big box home store.
