Yesterday I was struggling with a pool maintenance task that I have to
do 2-3 times a year, and I decided to build a PVC fixture to make the
task less of a hassle. It made the job way easier. Guess what it's for
(the top + piece isn't glued down and is removable).

I also built a nice PVC cart to store my kayaks, with wheels so I can
roll the cart out to the driveway when I load the kayaks onto the car.

What other non-plumbing uses have people found for PVC, beyond racks for
shoes.
