Pallet Pool, Part 3

How (not) to build a pallet pool, part 3...Issues! Once the pool was half full, some issues started to present. The sides started to bow out a fair amount. I screwed on a 2x4 and then a 2x6 perpendicular to that. It did help, but some of the screws simply broke from the stress, especially as we filled it some more. Also, the bottom pushed out in one spot where it wasn't inset in the ground much due to gate access.

The more water that went in, the more pronounced these issues became. Next, my pump pipe started leaking.

There was only so much tightening to be done. I ended up fixing it with silicone tape on the outside, and marine putty on the inside. As we got closer to 4 feet deep, I bought another strap to go around the middle to help with the bulging. We went to the pool supply store to get some chemicals. They tested our water there and told us what to buy. We had to calculate how many litres of water we had. I couldn't believe it when we came up with 20,000 Litres, but that's what it is. Guess how much a litre of water weighs? 1 kg. We had ourselves a 44,000 pound backyard paperweight. The bulging sides worred me. But the tarp seemed to be holding up just fine.
