I have a 40,000 gal in-ground pool, and, after much work and replacing of parts, we have determined there is a suction side leak at the connection at the base of the skimmer. Now that we've smashed up a bunch of concrete and dug a hole 3 feet deep, we're at a loss as to how to actually replace the connection. The skimmer is still intact, as is the concrete just surrounding the skimmer. We're trying to replace the connection under the skimmer from the filter side without damaging the skimmer. Has anyone dealt with this issue before?
