Bottom drain 110 mm ABS with aeration

Bottom drain for gravity-fed ponds with an air diffusion membrane. Allows for more efficient waste removal than pumping: no problem achieving a watertight seal!

The drain body is made of durable ABS, and the central tube supporting the diffuser is made of pressure-resistant PVC.

A very robust model for Koi ponds.

This model includes an air diffuser: 12/18 mm hand fitting (included) OR fixed connection via 20 mm PVC pipe (we include a PVC adapter kit).

Designed for installation on EPDM liners as well as polyester linings.

110 mm water connection: to be glued with Griffon WDF-05 adhesive.

Air connection: we recommend using our included connection kit rather than the original fitting.

Recommended air flow rate: 3000 liters/hour/m of depth.

ABS drain: glue the 110 mm PVC pipe using Griffon WDF-05 ABS-compatible adhesive.

To ensure a watertight seal, use a suitable adhesive.

No sealant! Unless you plan to rebuild your pool after a few years...

A PVC joint using pool adhesive melts the material and literally welds the PVC pipe to the ABS drain.
