The Kockney Koi Large Sump Bottom Drains are designed for the removal of solid waste and detritus. They should be installed at the deepest point in your pond. The bottom drain then leads into your filter system where all of these collected solids can be safely removed.
These are a must-have for any pond, and will help to keep your water crystal clear.
Included in the box is a sealing ring for pond liners, and a domed cover lid.
