Pond pump diffuser
by sharv999, published
When my pond pump is switched off the natural siphoning action draws water, and any nearby gravel etc, 'upstream' to the lower inlet pond via the impellor housing, This thing is designed to prevent the ingress of any foreign matter into the pump. Suits a 25 mm hose. Has the added benefit of creating a nice laminar flow ... Change the parameters in OpenSCAD to suit your own installation.
