Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I have never tried gluing flex PVC onto a barbed fitting so I'm not sure if it will work or not. I guess it's worth a shot. Let me know how it works out
From the looks of it that's flex PVC. Flex PVC is meant to be glued into a PVC fitting not clamped. Easiest fix is going to be to get some 3/4" poly tubing and use that.
When you push it on the fitting does the fitting go all the way in? If not try putting the end of the hose in some hot water to soften it up and then push it onto the fitting
