Poorly made junk that broke during installation.

Poorly made junk broke during installation. The vent line broke off for me, but I suspect any of them could. Total waste of time and money.

Water inlet

I installed this unit into my Lance Camper to replace the broken door. It did fit perfectly; however, water leaked out the water inlet. When I turned on the pump, water flowed out this inlet. I removed the unit and reinstalled with the same problem. Fortunately, I did not dispose of the removed unit. I removed the inlet from the removed unit and installed it into the purchased unit. Water flow problem resolved. It appears to be missing a spring retainer. I gave it 2 stars for the fit. Otherwise, it is junk!
