## Description

G Green Drain Waterless Trap Seal, 4 Inch : desertcart.ae: Patio, Lawn & Garden

Review: Good guality - Its good quality
Review: doesn't work after one year - edit (2025): after about one year of use it stopped working completely because rubber lost its elasticity. I started smelling sewer gas, after investigation took it out. Rubber hangs down leaving visible gaps between rubber, making it completely ineffective. The problem is with the largest one (4 inches). old comment: It works - somewhat. Each reduces sewer gas by a significant percentage, but not completely. I had to put in 3 at once to make it reasonably effective. Of course it depends how big your initial sewer gas issue was. One problem is that the silicone is soft and can be blown up by gas pressure. Its main advantage compared to other types that can be put inside a pipe is its resistance to dirt. I also tested spring and magnet traps, and they work perfect when they are clean, but they seem much more prone to things getting stuck in them (like hair) stopping them from working. Small water traps are perfect when filled with water, but they dry out easily and also have a tendency to fill with dirt. They should make a version with 3 seals in one.

## Questions & Answers

**Q: I can’t insert it inside the pipe as it’s rigid due to the screws for the cover.  Any idea how to manage this as I can’t take out the whole drain out?**
A: Dear Customer,

Many thanks for considering Green Drain in your property. The area where you insert Green Drain seal should be free from screws etc. If so, the SS Floor drain cover and grating should be removed and insert freely and after fixing the GD seal replace the St.steel floor drain grate and cover back. As the groove of the seal are flexible, it can easily accommodate the sizes for which you ordered. Still not resolved, then there is size mismatch ( please refer below table).

Check the enclosed instructions manual and below youtube link. It is a DIY product.
