Pump-out Pipe

How far off the bottom of the holding tank should pump-out pipe be and should it be cut at a 90 or another angle?

At the very bottom of the tank and a small air vent at the top. I would not use a fiting just the natural bend of the hose.

When I installed a new Dometic tank a few years ago it had a pretty neat design for the diptube. They used a 30 degree elbow near the bottom and then put a short length of pipe with a large chamfer on it . This allowed more open pipe area and still drained the tank to a reasonably low level without plugging.

I'll see if I can dig up a picture.

A square cut tube close to the bottom may plug easily, or leave "solids" in the tank.

Is the intake cut on the top or bottom of the "chamfer" piece?
