best way to attach vinyl tubing to submersiable pump?
 

whats best way to to attach the vinyl tubing to a pump? I cant use the hose clamp because its under water and it will rust.

there are plastic hose clamps.
otherwise brute force and tight fitting tubing?

attaching tubing
 

heat your tubing in hot water or with a hair dryer then attach it with a stainless or plastic clamp-you could also try zip ties

Use that. Since it is submerged, it needs to be plastic.

+1 boiling water, plastic clamp

does rona or home depot sell those plastic clamps?

I am sure you could source them elsewhere, BRS was the place I got mine, and thus I knew I could link to a picture for you!

Anywhere that sells parts for a phosban reactor would have ones for that size. And I think some of the canister filters use them still. I would check with some of your local fish stores.

JL does. they're on the back wall beside all the plumbing parts

Or you could try not fitting a hose to your pump and instead use rigid pvc :-)

If you must use vinyl then ya, try a plastic clamp or split the difference and fit the submersible part of the plumbing with ridge pvc then convert it (once the pvc extends out of the water) with a barb to your vinyl hose then you can use a metal clamp.

zip-ties. Even used them when replacing ends on garden hoses.
