On the new pool that I am having built, one of the PVC main drain fittings was cracked by the Pebble-Tec installers. No one noticed this until we filled the pool, only to have it loose 2 ft of water over night. The pool builder and Pebble-Tec are proposing to fix it by injecting pressure cement underneath the fitting. I am also thinking that they should apply a liberal coating of 3M 5200 sealant over and around the crack.
I would like some comments on this repair.
I should have mentioned that this is an in-ground concrete pool with a Pebble-Tec finish. It is located in west central Florida.
