After all, American Leak Detection agreed to redo the repair they did in May and did. However, the pool was still leaking!

So they came back and now they say it's leaking from the main drain (which they previously tested several times) and the crack (which they epoxied in July). Their suggestion is to disable the main drain, which will require draining the pool.

Now we keep the main drain shut off and the pool doesn't leak anymore. If they're going to disable it anyway, we figure we can leave it off. Will there be any problem with that?
