Suggestion on

installing the Retro Drain.

Take a white plastic meat board Place the retro drain in the middle of the meat board. Drill holes in the legs of the retro drain and down thru the meat board. Take Stainless steel bolt and nut and attach the retro drain to the meat board. You may also want to find a stainless steel pipe band to attach to the pvc pipe to the meat board also so it will not slip out of the retro drain. Also prevents the suction of the water thru the pvc pipe when pump is on so that the liner doesn't get suctioned up.

Installing the Retro drain on top of the liner of the pond to the pump.

Installing a Retro Drain in a Show Tank.............................. One of the safety factors is that if water escapes from the tank there will still be 4" or more water left in the tank for the koi.
