Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? 3" diaphragm pump to suck muck

I always thought a pressure washer tip to break up the muck a bit and just a simple 'x' across the intake so nothing over 1 inch got in.
I did some muck pumping with a 2" trash pump. 12 feet of water and I was working on ice. I used 17feet of 2 inch PVC with a 90 ontop to my suction hose. I also clamped 12 feet of 2inch PVC capped with air parallel with the suction PVC. The whole thing floated while sucking muck and you would simply have to push it down to suck up muck. It took very little effort but a pressure washer on the end would speed things up I think.
