It uses the same 1-1\/2\" HepvO valve as our \u003ca href=\"\/products\/sanitary-waste-valve\"\u003eBV1B\/UB kit\u003c\/a\u003e, but comes with a 1-1\/4\" in-line inlet adapter (CV7A\/U) instead of the 1-1\/2\" one. The outlet connects to standard 1-1\/2\" drain pipe.\u003c\/p\u003e\n\u003cp\u003eUnlike a conventional P-trap, HepvO does not hold a water seal. A self-sealing elastomeric membrane opens when water drains and closes afterward to block sewer and gray tank odor, so there is nothing to evaporate, slosh out on the road or freeze. The included angled adapter lets you install it horizontally or at an angle under shallow sinks.\u003c\/p\u003e\n\u003ch3 class=\"rvpg-specs\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul class=\"rvpg-specs-list\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e HepvO (Wavin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e BV1B\/UA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Waterless sink trap \/ sanitary waste valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet:\u003c\/strong\u003e 1-1\/4\" slip joint via in-line adapter CV7A\/U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet:\u003c\/strong\u003e 1-1\/2\" slip joint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit contents:\u003c\/strong\u003e BV1B\/U valve, CV11\/U angled adapter, CV7A\/U 1-1\/4\" in-line adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits sinks with a 1-1\/4\" tailpiece, such as many RV bathroom lavatories\u003c\/li\u003e\n\u003cli\u003eWaterless self-sealing design replaces a traditional P-trap\u003c\/li\u003e\n\u003cli\u003eHelps prevent sewer and gray tank odors from entering the RV\u003c\/li\u003e\n\u003cli\u003eNo water seal to evaporate, siphon or freeze\u003c\/li\u003e\n\u003cli\u003eInstalls vertically, or horizontally with the included angled adapter (ribs down, at least 1\/8\" fall per foot)\u003c\/li\u003e\n\u003cli\u003eHand-tight slip joints, no sealant needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHave a 1-1\/2\" tailpiece instead?
