Dranjer FS2 Sump Lid Drain Seal
Lets water into your sump while keeping radon, soil gas, odours and insects out of the basement.
Some sumps need to take water from above, such as a floor drain line or a downspout line, but a hole in the lid lets radon and soil gas into the basement. The FS2 is a one-way valve that fits into your sump cover. Water gets into the sump, and gas stays under the lid.
It's made for homes with an active sub-slab depressurization (radon fan) system. Dranjer is a Canadian company in Winnipeg, and its products are engineered and tested in the lab and in the field.
How it works
Inside the FS2 is a sealing ring. When water comes in, the ring lifts and the water drains into the sump. When the flow stops, the ring settles back into its seat and blocks gas from coming up.
Installation
- Cut an opening in the sump lid.
- Attach the FS2 to the underside of the lid and fasten it with the included screws.
- Set the strainer plate on top.

Common questions
Will the FS2 lower my radon level on its own?
It seals one way radon can get in: the drain opening in your sump lid. Whether that is enough depends on the home, so test before and after. The FS2 is designed to work alongside a radon fan system.
My drain is in the floor, not the sump lid. Which one do I need?
For a floor drain, look at the Dranjer FR2 for existing drains or the Dranjer FN2 for new construction.
