I am using the poly hose for inside my pump box, outside of it before it goes in the lake and also within the diffuser cages I built. I noticed this weekend that the majority of connections where I used hose clamps were leaking air. At the elbows, the tee, the valves, much of it had leaks that weren't there when I first set everything up.

None of the weighted hose connections had leaks though, only the poly.

I used soapy water around all of it to pinpoint them. When I assembled everything, I tightened the clamps with a screwdriver. I thought I had cranked them down well too. I used a ratchet this time and stopped all the leaks.

Just thought I'd throw that out there in case anyone else finds they have a similar issue while using clamps and that hose.
