Downspout Universal Brass Floor Drain core, Shower Floor Drain backflow Preventer, Suitable for 1.4''-2.0'' Caliber (2, Brass)

Elimina el problema de insectos y olores

A nice solution for a problem i never knew existed. The simple fact that it does makes me realize that this problem is quite pervasive. This valve went in simply and the odors were eliminated.

I've been dealing with an annoying issue in my basement washrooms that don't see daily use: unpleasant smells and the occasional bug making its way up through the dried-out floor drains. I stumbled upon the COLDDD Downspout Universal Brass Floor Drain Core and decided to give it a try – I'm so glad I did! This product has been a perfect solution. I've now purchased and installed three of these cores in my basement washrooms, and they have worked flawlessly. The genius of this little device is its unique mechanism. It's made of solid brass, which feels durable and high quality. The core is designed to open when water flows down the drain and then automatically shut completely when the water flow stops and the drain dries out. This has completely eliminated the sewer gas smell that used to emanate from the drains. As an added, very welcome bonus, it also acts as a barrier, preventing any insects from crawling up from the pipes. Installation was straightforward, and they fit perfectly into my existing floor drains. For anyone experiencing similar issues with drains in areas that aren't used frequently (like guest bathrooms, basement washrooms, or even utility room floor drains), I cannot recommend this COLDDD drain core enough. It's a simple, effective, and well-made product that solves a common and frustrating problem. A brilliant invention!

Buen producto con acabados funcionales y duraderos. En un inicio sólo enviaron uno, me comuniqué con el vendedor y luego enviaron la otra pieza

During a recent bathroom reno, I ran into a challenge there wasn’t enough room to install a traditional P-trap for the shower, so I had to run a straight line instead. I needed a reliable way to prevent sewer gases from coming back up, and this Downspout Universal Brass Floor Drain Core was exactly the solution I was looking for. The fit was spot on for my application, and I was genuinely impressed with the build quality. It’s surprisingly solid and well-made, especially for such a simple design. You can tell it’s built to last. Installation was straightforward, and I added a small bead of silicone just to keep it secure. That said, if I ever need to remove it for a clog or maintenance, it will be incredibly easy to take out and clean the line which is a huge bonus. It performs exactly as advertised and gives me peace of mind knowing gas won’t return through the drain. This worked so well that I’ll absolutely be using these in future installs. Worth every penny. Highly recommend!
