Air leak update

[PoolCleanerMom]

The pipes aren't connected under the sleeve. Basically they are butted close to each other about mid-way, then the hose clamps provide the friction to hold them together as well as seal. Did whoever plumbed the piping into the filter use pipe thread compound instead of teflon tape? Tape doesn't work very well for larger fittings, and may prevent you from getting the fitting fully seated while still not sealed. Looks like you still have some space between the pump front and the screw in fitting, could be an issue. Mine is fully seated.

hubby checked the filter piping and confirmed that the installer *did* use thread compound. Also he tightened those connections but we're still having leak issues. Since it seems to be a slow/intermittent one I'm not sure if the "run water over the connections" test would be helpful.

Any other ideas for the pvc/copper pipe joint?
