All Koi ponds should be fitted with bottom drains, and
we strongly recommend this.
This bottom drain is well made and is suited for use with
110mm waste pipe.
*NOTE: It cannot be used with pressure pipe.

Kockney Koi 4-inch Bottom Drains
Large Sump Bottom Drain For installation at lowest point
of pond. A must for gravity fed systems. Ideally suited for
draining heaver particles to waste or filter system. Can be
reduced down to 3” if required. 4” (110 mm) exhaust.
Known worldwide for its quality and design. This unit completely replaces
the "Standard Bottom Drain".
The most noticeable feature is the extra connection in the sump of the
drain. This allows the air supply hose to enter the sump independent of the
water outlet pipe, thus eliminating the possibility of restriction to the
water flow and somewhere else for blanket weed to attach.
