The 4" Bottom Drain comes with an anti-vortex drain cover for bottom sweeping action.

These bottom drains can be used on liner ponds or on concrete ponds.

Bottom drains are an important part of any pond. When installing your bottom drain, make sure that it is installed at the lowest point of your pond. This will ensure that the waste will travel into the drain and into your filter system.

  A 4" intake allows for larger pumps to grab water from a larger area reducing pump pressure. Should be used with 4" PVC.
