Model F-S2 Sump Drain

This is exactly what I needed for my radon mitigation. I had an existing sump pit between the water heater and washing machine. It was the only place I could have a noisy radon mitigation system installed. Problem was that radon mitigation is a closed system and the company didn't have the means to allow water to enter the sump pit in case of accidents. I had the company customize a cover to accommodate the the pvc and this one-way valved drain. Viola!

Great product. I followed the very detailed instructions to mount it in my lexan sump lid with some black RTV silicone and it was very easy. The parts are very well machined and the design is remarkably simple and well thought out, future cleaning and mainenence will be a breeze.

Bought this to add a drain to a sump cover that was sealed because of radon issues. Simple design and installs easily. Tested it by draining/flushing my water heater which is located right next to it.

Works like it should. Easy to install.

Great concept. Easy install. Hope it works if I need it.
