Yeah, the entire underlying problem are the pipes that lead to the pool as many have tried to tell him. The pipes leading to and from the treatment machine need to be fully replaced. When the pool was renovated in 2012, the pipes installed were for the wrong application. The land the pool sits on is formerly wetlands. So special attention is required for putting in pipes in that area. This wasn't done and so the soil is literally crushing the pipes allowing water treatment to leak into the surrounding soil.

This is why they've had to have people physically go out there and manually treat the pool. The problem is that the treatment is never making to the pool in a large enough volume to make a difference. But the manual treatment requires people in large "unsightly" protective gear to wade through the pool and treat the water. Then they have to rope off the section that was treated to ensure no one tried to enter the pool until the treatment has diluted enough.

Trump keeps doing the thing Trump is known for, cutting corners that ultimately mean more money is spent long term. The problem is the pipes. They need to be replaced. But then the pool has to be closed for large construction and the short term cost goes up. So Trump keeps just putting a band-aid on it over and over and over again like the idiot he is.

He's been told what the issue is and what the fix is. He just wants a short-term "fix" so he looks good. He's not actually interested in fixing the pool. The pipes have to be ripped out and new ones installed. That is the only true fix.
