I am trying to dry fit the pieces of my Valterra dump assembly, and I cannot figure out how best fix my problem.
Here are the two pieces involved:
1. On top, a female NPT fitting (that will be attached to the bottom of the black tank sitting on the floor of the coach)
2. On bottom, male Threaded Flange (that will attach to the rest of the Valterra assembly in the belly pan)
The male threads on the flange end up tightening before fully seating into the female fitting. The result is that the connection of the two pieces causes a wide gap between the upper piece and the top of the Valterra dump assembly. As a result, either:
1. The Valterra assembly hangs too low into the belly pan, which will mess up the alignment with the piping coming into the Valterra (see here
2. I will have to raise the black tank off the floor of the coach, and I would prefer not to do that because the top of the toilet already is high).
Would it be possible to cut off some of the threading on the male threaded flange?
I am thinking that I could mount the flange onto a block of wood for stability and then use my bandsaw to cut off part of the male threading so that I get a tighter fit. Doable? Sensible?
Any guidance would be appreciated.
