Its freeze-proof design and threaded connections make it a durable, easy-to-install solution for a variety of sanitary fixtures, ensuring enhanced plumbing efficiency and odor control. ## Description HepvO is a self-sealing valve designed to close the waste connection below a sanitary fixture to prevent the escape of foul sewer air into the dwelling. HepvO unlike conventional waste traps, does not rely on trapped water to create a seal. Instead, HepvO uses a self-sealing membrane, which performs the same function as a water seal trap but without the risk of evaporation, siphonage, or cracking under freezing conditions. The HepvO valve means enhanced plumbing design and system efficiency, without compromising performance or risking the escape of foul air into the living space from the drain or sewer. Typical Applications: Lavatories, bath tubs, sinks, bidets, washing machines, garbage disposals, overflows, dishwashers or showers. ## Features - Model number: BV1BUB112 - Country of Origin: China - Brand name: HEPVO ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NLMPLDU | | Best Sellers Rank | #86,107 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,462 in Pest Control Traps | | Brand Name | Wavin | | Connector Type | Threaded | | Customer Reviews | 4.6 4.6 out of 5 stars (1,070) | | Exterior Finish | Brass | | Global Trade Identification Number | 05027888240361 | | Included Components | Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" | | Inlet Connection Size | 1.5 Inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 9.25 x 6.63 x 3 inches | | Item Type Name | Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" | | Item Weight | 0.34 Pounds | | Manufacturer | HEPVO | | Manufacturer Part Number | BV1BUB112 | | Material Type | Brass | | Model Number | BV1B/UB | | Number of Ports | 2 | | Outlet Connection Size | 1.5 Inches | | Outlet Connection Type | FNPT | | Size | 1-(Pack) | | Smart Home Compatibility | Not Smart Home Compatible | | Thread Size | 1.5 inches | | Thread Type | 1.5 inches | | Unit Count | 1.0 Count | | Valve Type | Sanitary Waste Valve | ## Product Details - **Brand:** Wavin - **Exterior Finish:** Brass - **Global Trade Identification Number:** 05027888240361 - **Inlet Connection Size:** 1.5 Inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 9.25 x 6.63 x 3 inches - **Material:** Brass - **Number of Ports:** 2 - **Outlet Connection Size:** 1.5 Inches - **Outlet Connection Type:** FNPT ## Images ![Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" - Image 1](https://m.media-amazon.com/images/I/71p9JlMAUsL.jpg) ![Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" - Image 2](https://m.media-amazon.com/images/I/81NMDcTIo6L.jpg) ![Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" - Image 3](https://m.media-amazon.com/images/I/81fqWQfuoiL.jpg) ![Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" - Image 4](https://m.media-amazon.com/images/I/31WK8QZzH8L.jpg) ## Frequently Bought Together - Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2" - Valterra A01-2012VP Silver Carded Shower Drain - All Season Marketing BV1B/UA Hepvo Waterless Waste Valve 1-1/4" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/22087315-wavin-bv1b-ub-hepvo-sanitary-waste-valve-1-1-2](https://www.desertcart.sg/products/22087315-wavin-bv1b-ub-hepvo-sanitary-waste-valve-1-1-2) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-01*
