    What is the best way to glue this to PVC Elbows , Couplings , etc:
    When it gets push in it will only go 3/4 of the way in , Should I sand the PVC and try to get it in all the way then glue, And do you use regular PVC Cement and Prim?

    Hummmm........I chose to use flex PVC instead, Christies' Hot blue glue for that. Not sure for this under higher pressures, 5-12 psi might not hold for many glue types etc with the ribbed flex spa stuff. E6000 should work though if you use it and let it cure good for 2 days.

    They make specific fittings and such for the flex hose, might go to a store that sells the stuff etc or call and ask them(best).

    Hi ink,

    I used 1" PVC flex hose and just used normal PVC fittings, elbows, couplers, etc.

    I just used the normal PVC glue.

    I cleaned both ends of the connections. Then place glue all around the spa flex. Then push into the PVC fitting. It will go in further.

    I had them in use within 60-90 minutes, and now 6 months later, no issues to report.

    I used 3" flex when I plumbed the drains for the pond and I had issues with it not seating properly and also wanting to push out of the fitting if you did not apply pressure long enough. I found beveling the edge of the hose and cleaning the fittings well did help, but there were still a couple of fittings that were not perfect. But no leaks so far. I might build a press if I had the big fittings to do again.
