2-2 1/2" to 3" via muffler adapter

[lostinthewoods123]

Have a 10"x60" sluice. Picked up a 212cc 6.6hp 2" water pump in and out, 151 gpm. Am buying the nozzle and hoses for a 2". But want to modify the suction nozzle inlet to a 3" by muffler adapter. Put in a bolt or two to keep out the big rocks. It'll be a 2" anyway or maybe a 2 1/2" with the 3" mod?

Sounds like you are flirting with having a clogged up hose. If anything use an exhaust pipe reducer adapter that goes from the outside of the suction nozzle to no more than a 1/4" less than the inside diameter.

Really though it's better to use the suction nozzle as is and just be careful as to what you allow in and how much at a time. With a 2" you need all the material you can get. Chokeing down the nozzle is self defeating. And making it larger even with classifying cross hairs will allow in too much overall volume leading to a clogged hose.

GG~

I cringe every time I read about people chocking down the nozzle. Slow and easy wins the race. Of course it took me several years to finally learn that

NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO bolts,bars or other insane bs. 2" hose needs a 2" nozzle with either a knurled edge or ring slightly reducing it down. You failed to mention a header box or the new riffles now required as when going slomo sluice to high velocity modified hungarian mandatory. READ mo-John

Thanks for all the info. 2" is what I'll go with, no mods. Great forum.
