I spent eight months pulling wire into street lights and nothing sucks more than hitting a 90 that's come apart*. All thanks to morons 15 years ago who didn't give a shit about gluing PVC properly.
*Actually, having to dig it up and fix it sucks more. But that wasn't my job.**
**What's really going to suck is all of the street lighting that fails in ten years thanks to the shredded insulation from us pulling wire through bad joints. Exposed aluminum will oxidize sitting in wet PVC underground.
I typically have problems with any solvent that comes in a can of that design. Also I'd probably fail this at Step 1 and not realize this until Step 7 followed by throwing everything away and drinking a 6 pack of beer as quickly as possible.
