Radon Sump Basin 18 gal

This polyethylene basin serves as a radon sump trap with an 18 gallon capacity and an overall height of 22 inches. It features a 3 inch vent and a 4 inch inlet diameter for system connections. The component is designed for sub-slab depressurization installations. Builders needing a different capacity or vent configuration cannot use this model.

Polyethylene Construction

The basin is moulded from polyethylene for corrosion resistance in below-grade environments. This material choice supports long-term durability when exposed to soil moisture and radon mitigation chemicals. No additional accessories or software are included with the unit. Installers must source piping, seals and cover assemblies separately.

Questions about this item

Will the polyethylene basin crack or need replacement after years in the ground?

The basin is moulded from polyethylene, a material chosen for long-term resistance to soil chemicals and moisture, so it does not require scheduled replacement under normal conditions.

At what water level does the 3 in vent become the limiting factor during sustained inflow?

The 3 in vent handles airflow up to the basin's 18 gal capacity; sustained inflow beyond that volume will cause water to rise above the vent and restrict drainage.
