I used this and the smell is gone. A also like that it doesn’t have any mechanical device which can fail in time. This is cleverly designed. Allows water to go through but blocks odors getting out. ### ⭐⭐⭐⭐⭐ Worth it! *by T***E on April 3, 2026* These things worked like a charm to keep the sewer smell from coming through my shower drain(shower over concrete floor) we could not get the trap to set right so we kept getting the smell until we found these. They last a while didn’t affect water flo or drain speed. Worth the money! ### ⭐⭐⭐⭐ Returned item, didn’t work for my application. *by O***Y on July 13, 2025* I attempted to use this product in a sink drain pipe with an air conditioner condensation line offset . Just didn’t fit well. These might be better suited for drain pipes that don’t have a condensation line offset, but for my application, they just didn’t work well. I may reconsider them for my RV one day to prevent grey water tank smells from entering the camper. These are well made and do provide a tight compression seal. ## Frequently Bought Together - HLZC Drain Backflow Preventer, One Way Valve, Adjustable Silicone Sink Floor Drain Trap for Pipes Tubes in Toilet Bathroom Kitchen (Blue-4) - Shower Floor Drain Backflow Preventer Valve Sewer Core Drainage Insert Drain Plug Hair Catcher Gas Sealer Floor Strainer Trap Seal (Blue-2Pack) - COLDDD 2Pcs Odor Proof Floor Drain, Floor Drain backflow Preventer, Shower Plug, Magnetic One-Way Drain Valve, Prevent Odor Dispersion in Bathrooms, and Kitchens (1.5''-2.0'' Caliber) --- ## 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.bo/products/214387923-4-piece-set](https://www.desertcart.bo/products/214387923-4-piece-set) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-08-23*
