PVC Cement on pipe with flowing water

Around here we'd use a self-restraining compression coupling. Not the cheapest, but reliable.

Dresser style 90 are good. spec sheet says 150 PSIG(Different gasket/grips good to 1000PSI+). If those aren't available, an IPS pack-joint coupling would also work. These I can install and know there will be no call backs.

For solvent welding, you're looking for a fast-setting, water tolerant PVC cement. These are typically a fluorescent blue and called "Rain R Shine" or "Wet 'R Dry." These will hot set and kick in under five minutes. They will also stain everything and cause chemical burns, so be careful and all that jazz. If I was forced to use this, I'd restrain the heck out of any nearby joints. It still requires the purple primer.

Good Luck!
