W. Lim Bottom Drains 

The W. Lim Bottom Drain is designed with a full sweeping bottom to help prevent waste from getting stuck in the drain. It can be easily installed on concrete ponds or liner ponds. The W. Lim Bottom Drain also comes with an anti - vortex drain cover for bottom sweeping action. The drain has a 10" opening that slopes down to a 3" or 4" pipe opening.
We apologize, but we are no longer carrying these bottom drains.  If you would like a great bottom drain, check out the Tetra Bottom Drains.
