Learned something new the other week. I had a small leak develop around a tee in some PVC I built a couple of months ago. Itty-bitty pinhole leak but the line is under 100-120psi so water shot out a good 6 feet before hitting the floor. I circled in red where it was on the system:
There's not a lot of room to work with here so I didn't want to cut into it. I pulled that section out (you can see the unions on all three sections) and took it to the shop and put it on a bench. I closed the top shutoff valve, put tape on the hole to the left, and stuck a shop vac on the bottom bit. I then alternated between primer and glue 3 times, being pretty liberal with it all, and let it dry for a solid hour. Stuck it back in the system and it's held solid for about a week. 250,000 gallons have gone through at 120psi and not a problem yet.
I got the idea from this video:
