It may have been full and smelled like a black swamp. I could see the realtor having it drained before the house went on the market and the wind billowing the brittle liner has since damaged the liner.
This is a really interesting theory. Upon inspection, it turned out they winterized the pipes before it was closed. So draining it and putting holes in might make sense.They could have discovered a leak, then drained it to avoid a swamp and put holes in the liner to keep it drained.
The surrounding area drains really well. But there was also no damage to the nearby patio, pool deck, or basement.Cement base just means the base, not the walls or whatever joint is between the walls and the base. (Cement is also not always concrete, sometime vermiculite, and there’s likely no rebar in the floor so cracks are almost a certainty)
Concrete is also not waterproof. If the liner has been ripped for a while, there’s plenty of time to saturate the surrounding soil. It’s for sure potentially very damaging to the surrounding area.
if so, it was a very bad idea. If it was holding water, it should not have been drained if they planned on keeping the integrity of the pool structure and surrounding area.Another comment suggested they drained the pool and put holes in the liner to keep the pool from filling up.
The list of stupid things that people do to their pools is a mile long. This will not be the last entry. (If it's what happened)If it was holding water, it should not have been drained if they planned on keeping the integrity of the pool structure and surrounding area.
It can be done with air, but is not recommended.When they pressure test the pool plumbing it's done with air. They should be able to test adequately in that condition. Make sure your tester is familiar with pool plumbing. Are you aware of any of the pool history such as when was the last time it was used?

Water.What else would you do it with?
