RELN Uni-Pit Vortex


RELN Uni-Pits are the fastest and easiest pits to install. The unique vortex design prevents water pooling in the bottom of the pit, removing a common breeding place for mosquitoes. The Uni-Pit vortex inline surface water drainage system eliminates the need to risers, as vertical pipe can be cut to the required depth.
