Before
The existing sump. No back-up and an open lid.

Sump Upgrade
We can see the air tight lid and back-up system. We installed a new cast iron submersible pump, too. Radon mitigation systems need air-tight lids over sump liners.

Radon Fan and Pipe
This is a radon mitigation system. It goes into the basement floor, to draw air from under the floor. From there, it is exhausted outside. They require a very small amount of electricity to operate.

Exit Point
The radon pipe exits the home through the header of the basement.
