Here in Western WA, its rare that it hits 85-90 degrees, but this week has been an exception. I'm not used to working in 90 degree weather, so I've been suffering. I had a service call that required me to, among other things, install a double check on the irrigation take off. The line running to the house was 1" PVC, about a foot down, the originally irrigation installer (not us, homeowner job), used a Compression Tee aligned verticly, ran the pipe up 6" and elbowed, and then had a cheap slip ball valve. As I was digging the pipe up to make room for a double check, I noticed the elbow before the ball valve was seeping, seconds later, the elbow blew out and I got soaked like a drowned rat. It felt GREAT Hehee. Closer inspection of the elbow once I shut off the house main showed lots of primer stains, but not a bit of a glue bead anywhere, yet other fittings in the area had obvious glue stains...I think the only thing holding it together was the dirt that I removed.
