I am running a long suction hose from the river to a pump, in order to get water for watering my lawns during the hot, dry summer. The problem is that I had to join/splice two sections of flexible PVC hose between the foot valve and the pump. Because it's on the suction side of the pump, I can't have any air leaks, of course. I have tried using just the normal method of connecting the two sections of hose with a plastic, barbed connector and then clamping it with the typical little silver hose clamps that have a small "worm" thread (don't know how else to describe it) that is tightened with a screwdriver. No go; it leaks water and sucks air, no matter how much I tighten those clamps. So, here's my question: is there another way to connect those two sections of flexible hose together, such as with an in-line connector that is cemented in place? Can you glue flexible PVC? I know you can cement rigid PVC, and have done that, elsewhere, but what about the normal flexible PVC hose? And if gluing them together isn't an option, does anyone have an idea that will work, giving me a nice, strong air-tight connection?

Not sure what you mean by flexible PVC. Are you sure it's not black poly pipe? Are you using the right barb fitting to splice it? The barb should be so big that you need to heat up the poly pipe to get it on. Are you using two gear clamps on each side (4 total) and staggering the worm gear on opposite sides?

If it is actually (white) flex. sch. 40 PVC, it is WAY too stiff to clamp. It glues like rigid pvc pipe. Prime well.
