Sump Before
One-piece lids are tough to access and work on. With radon mitigation systems, we need an air-tight lid.

Sump After
What a difference! We replumbed the ABS with clean white PVC. The new pump and backup is installed along with the lid. The battery is a special design meant for low power over long period of time (versus a car battery, which needs a lot of power for a very short period of time).
