To not highlight the power of heating PVC pipe to conform into any shape you want is to kind of miss half the PVC story.

You can do without unions altogether by just heating one end enough to flare it, then slide the other pipe into the flare while heating more to let it conform and produce a union lap joint in-situ.

Mastering heating is key to avoiding wasting money on tons of adapters which rarely even produce exactly what you want.

Interestingly, plumbing your house with PVC water pipe is not a fantastic idea and is not allowed under most plumbing codes. The specific issue is that PVC loses strength at higher temperatures, so performance at household water pressures with household hot water is somewhat marginal. Manufacturers don’t rate their pipe at all above 140 degrees F. Having your pipe burst when you run hot water through it is undesirable, and inspectors can’t easily tell whether a pipe is a hot water pipe or a cold water pipe, so PVC is generally not permitted for indoor potable use.

CPVC has much better hot water performance, isn’t terribly hard to find, and glues just like PVC as long as you use the right glue.

(Very confusingly, CPVC pipe is usually sold in “copper tube size” instead of Schedule 40/80. But this means that many push-to-connect fittings work on CPVC pipe.)

You can make a far more powerful shooter using propane / butane and a tennis ball. And more dangerous! Can also store balls in pressurised pipe to keep them bouncy for longer.

A potato cannon. With hair spray re-packaged as Susie's Special somethin'. It was a Christmas present from my husband. Best gift ever!!!
