Fit in perfectly super easy to install. Saved tons of time and extra money because of p trap not installed, this replacement worked perfect! Review: It works! - I got this drain to keep odors in my shower at bay, and I am very happy with the results. No more odors. At first, I installed it only one inch deep, and that caused water to pool. So I installed it at 2 inches as recommended, and the water no longer pools. I guess it needs the weight of the water that two inches provides for the flap to open and drain the water. I measured my drain and bought the appropriate size, so the fit and size are perfect. Regarding durability, I got this device some months ago, and I have not had any issues since. Totally recommend it. ## Features - The Green Drain 4″ model offers enhanced versatility and protection for pipes measuring 95-104 mm in diameter. - Simple installation - Please make sure to recess the Green Drain 2-4 inches into the drain to allow water to properly pass through it.

Without the center plug, a small amount of water drips through, but if a basement was flooding under 2.5' this would hold back the vast majority of water, preventing a lot of unnecessary water damage. **Q: Can this be installed in clay tile?** A: If you are referring to a clay tile pipe then yes as long a it is a tigjt fit as clay has a tendency to wear faster vs steel and could be slightly bigger than 4”. **Q: If it's just pushed in, how does it keep its position, could it just fall straight down a 2" straight pipe and get stuck?** A: Usually the 2 inch pipe is only a short pipe leading into a smaller pipe or a bend. If your drain is a straight 2 inch pipe the whole way down then this would not work for you. This drain is designed for showers or drains that should have a P Trap but don't. **Q: What are the dimensions of the 2" unit?** A: it fits in a standard sched. 40 2" PVC pipe. so slightly over 2" ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfectly as p trap replacement *by A***R on January 30, 2026* Awesome, worked like a charm.

Totally recommend it. ### ⭐⭐⭐⭐⭐ Works great *by O***1 on September 24, 2025* I think the bad reviews are for small drains. That said I’m using this in a 5” basement floor drain that goes straight into the sewer. My washer and utility sink drain into it, and it has no P Trap in the concrete floor. It smelled like the house sewer, stunk up the whole basement and house. Because of the immediate bend in the drain a Sureseal wouldn’t work. I popped this in and it’s been working for weeks without a problem. I’ve been very happy with it. I’ll probably buy a few spares, but it has been holding up to a house of 4 washing clothes, utility sink use, and a 3 Ton AC condensate drain line. It can handle a high flow of water, (like many many many gallons at a time) so I’m not sure what the negative reviews are about it draining slowly are about - probably bad plumbing and not the device itself. ## Frequently Bought Together - G Green Drain Waterless Trap Seal, 4 Inch - EZ-FLO Stainless Steel Floor Drain Snap-in Cover for 4 Inch Pipe, 5 Inch Outside Diameter, Satin Finish, 43472 --- ## 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.co.uk/products/82072198-waterless-trap-seal-4-inch](https://www.desertcart.co.uk/products/82072198-waterless-trap-seal-4-inch) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-15*
