I found a couple 1/2" sprinkler fittings at Home Depot, screwed them together and installed them. Total cost was a couple bucks vs about $30 to replace in kind. No more occasional odor and no chance of a leak,


If these are needed for a 'vacuum' breaker, then why the roof mounted vent. I can't see any chance of any tank vacuum if that roof vent is clear. I don't recall our last 5er, a Canadian built Titanium or the two TTs preceding it or even the old Newmar Kountry Aire having one of these gadgets - and ya gotta believe I worked on every piece of plumbing at one time or another on them
