Nah, I've done a LOT of PVC work and ALWAYS keep spares of fittings just for mistakes. I had to COMPLETELY re-plumb my pool as soon as the installers left: They had used internal barbed fittings inside of TigerFlex so it was leaking everywhere instantly! Funny, because they did everything else very well. I re-fit it all with proper Schedule 40 glue-on fittings and they never leak. PVC work is Plumbing For Dummies so I'm a shoo-in! I've done upgrades over the years, like building a manifold so the solar panels could be split up and used more effectively, and when I added to the pool deck, I had to move the pump and filter...and re-do the conduit for the pump's 220v wiring. The conduit's just like PVC only easier, but the wiring inside is tougher.

The way to avoid the "Swear" component is "Dry Fit"!
