The HepVo valve is a waterless trap the replaces the standard P-Trap. See more about it including my installation video at this Love Your RV! blog post – https://www.loveyourrv.com/upgrading-rv-drain-system-hepvo-valve/ I also show off my wire shelving mod that gives me a little more storage space under the kitchen sink. And show how I can easily flush my galley tank now. RVHH Chief Cook and Bottle Washer - LoveYourRV.com 1 user thanked author for this post.
