We recently purchased a home with a large pool. The house was discounted due to issues with the pool. The pool was built in the late sixties, and repaired on the cheap several times. We took on the adventure of repairing this pool. There are multiple cracks in the plaster that have been repaired. The pool light has been plastered over and the main drain has been covered over. The leak is located at the bottom of the last step and there is water coming back out of the crack. This site has been a great resource as to what to look for. We plan to do decking, plumbing, and coping ourselves.
