Review on 🚽 Prest-O-Fit Blueline Ultimate Sewer Kit: Your Solution for Efficient Sewer Connections by Trey Samuels

I connected this hose to the van and started draining the black tank. Immediately, the hose slipped off the coupler and shit went everywhere (literally!). Upon closer inspection, it turns out that this design uses friction to keep the hose on the coupler. Not a good design. Interestingly, Revain really wants to return this product for a refund. So I guess I'll put on a glove and put this stinky slink in a box, and God help whoever opens that box!
