Lets say you had a 1 gallon plastic / PVC bucket.

It has a hairline crack around 80% of the circumference.

You can only get to the inside of it, no access to the outside.

How would you repair it?

Some requirements.

It needs to be absolutely 100% waterproof and leakproof.

Has to be 100% non toxic.

If you've not guessed yet yes, this is for my pool debacle.

We thought we found the source of the leak earlier in the week but it once again drained overnight.

Builder and I spent a few hours yesterday scratching our heads.

I suspected the problem was one of the two main drains.

Finally found the hairline crack in one of them.

No it cant just be caulked up.

The fix right now looks like jack hammering up the floor of my brand new haven't even had a chance for hotub sexy funtime with the missus yet jacuzzi.

Yes I want it repaired correctly and just wondering if anyone has a thought on in place repair.

My thought was caulk up the crack then get a thin flexible piece of PVC or other non permeable material to go 360 the full inside of the drain extending maybe an inch above and below the crack slathered in some strong adhesive to reinforce the structure.

Yes? No? Stop obsessing and let the builder you paid to provide a leak free pool deal with it? Drink more?
