Rectorseal SureSeal SS4009 4インチ 床排水トラップシーラー ブラック 1パック

This is the only one that would work in my basement floor drain, as my drain curved right away. All other's were to long and would hit the curve . This fit perfect, the rubber sealed the drain tight, no more smell in my basement.

I bought this mostly to prevent radon gas from coming up the drains as my sensor told me this floor drain was a hotspot. The seal is good and the fit for 4-in strain is perfect. Construction quality is very good. Better than the oatey 3in silicone drain seal I bought. I will update if I remember to comment on whether radon levels drop.

This thing saved my home and a lot of renovations.I hooked this up to my basement cleanout so the water under my home can drain when needed. I've had two basement floods and since I"ve installed this the water doesn't have a chance to build up. I do think it's overpriced for what it is but it's a lot cheaper than the 18,000 dollars to install a floor draining system.

I had an older model of this trap seal that worked well for two years. Then the flaps lost contact and started letting gas through. I emailed Rectorseal asking about repairing or replacing the flaps. They got back to me immediately (at 10PM) and offered to send me a replacement. This is expensive for a neoprene flap, but it works. And the redesign looks more durable than the one I eventually had trouble with. More importantly Rectorseal stood by their product, no questions asked.

2015: The drain seal was installed in about 15 minutes (which included cleaning of the drain pipe at the top to ensure a complete seal. The smell was gone as soon as the seal was installed. We have had no issues with the seal and it has been 2 months. 2024 update: This product lasted over 9 years before the sewer gas started leaking through the seal. I am replacing it with the same manufacturer's product. I am a very satisfied customer!
