There will be one 3" inlet for the toilet and one 1-1/2" inlet for the vent. Is there anything wrong with using these or should I find someone to plastic weld in the inlet fittings?
When the trailer bounces around, in time, you will find out that the grommets leak.
Of course you will only find that out on a trip, where you can't do anything about the leaks, until you get back home.
We refuse to use them.
