My dad's back yard pool was constructed in 1974. About 20 years ago came the wobbly/bouncy bottom. My daughter thought it was more fun than a bouncy castle.
- Hydrostatic valve not checked?
- A ruptured inlet pipe (fixed a year ago) was causing a massive water loss.
Two months ago, it popped like giant blister. The yawning crack is nearly 3 metres long (9 feet). You can see the concrete base through the crack. Miraculously, the water level doesn't seem to be going down. The water quality/colour is still great. When I visit, I vacuum/chlorinate it and swim as normal.
How long can this last?
The suspense is killing me.
