Issues with Moen 3330 3-function valve install
I am currently building a kerdi shower with a Moen vertical body spa and have come up with some unexpected issues with my 3 function valve (3320)…
I bought this whole kit new from a nice fellow on e-bay and am starting to bite my fingers as to either I can get a replacement valve from Moen or deal personally with this guy who happens to live in Hawai (I’m in Canada!):o
But first let me explain what my issue is….
My water inlets are threaded ½ inch and I am going the Wirsbo route with ¾ within the system which consists of 4 body sprays and 1 shower head . I attached ½ male NPT to ¾ brass fittings that I laced with Teflon and leaned a bit too hard on the valve while using my wrench that the top outlet fitting to the main body solder snapped ! See attached pic!
No biggy, I figured I can unsolder and clean and flux the joint pretty easily. But before doing so I figured I would remove the pressure balancing valve and the check valves because they have rubber rings that could get deformed by the heat of an extended heat necessary for a brass to brass solder.
To my surprise I discovered a small hole or defect in the main body where the cold water check valve cartridge slides in (See pic again!)
The hole is behind the thread that seals the valve and pretty much is where the rubber gasket makes the seal when opening or closing the check valve.
Can I live with this ??? Could a malfunctioning check valve cause problems in the future ?
Could I leave it “open” and add an accessible ball valve a couple of feet away ?
What would the pros do if they were in a similar situation :) ? Moen has a really good warranty but this is void now because I am the second owner and do not have a store receipt...
Did I shoot myself in the foot :( when purchasing this online…
Anything I should look out for when soldering the main parts back together again ?
Any “positive”comments, help greatly appreciated !
