RV Waterless P Trap Self Sealing to Prevent Foul Odors | HepvO Sanitary Waste Valve | Waterless Valve | P Trap Replacement (1 1/4")

This works fine but doesn't feel as substantial as the original that I replaced, but it essentially does what it's suppose to do. It comes with some adapters if you are using it in a drain line configuration setup under a sink.

The interior piece that is supposed to seal out sewer smells did not close all the way. The opening was large enough that when pointed out the window and looked through, it was no problem at all to see the trees across the street.As an earlier reviewer commented, the threads on the ends do not match any of the plumbing parts at my local hardware stores. Another reason not to go with this product.I've read great reviews about using Hepvo instead of p-traps. I guess this manufacturer isn't building to the same standard or I got a faulty part. Either way, I did not have time in my plumbing repair to wait to get a replacement to find out which it might be. I returned this item for a refund.

Installed for a 32x32 shower stall in a cargo trailer conversion.

Recievd this in good packaging and from the outside it seemed ok. When trying to actually use it it is essential useless, the threads are very fine and the quality of those threads are horrible. the parts cannot be assembled as the threads cross thread and I have yet not been able to get this together, and because the threads are not a common thread you cant just go to Homie depot and get anything that will match and attach! For me this item is useless.
