I just found your site, my knowledge has already increased due to the Pool School. I have a question regarding a pool leak. After several failed attempts to have at least three different leak detection companies charge me $225 plus to locate the leak (they schedule and no showed). I decided to take this on myself. We purchased this house in August of 2012 and acquired many challenges regarding the pool, which has provided a huge learning curve as new pool owners; without the benefits of enjoying the pool yet.
Today, I discovered that the shimming basket area has cracks. How would I go about fixing this problem? When I fill the pool, it always seems to stop at the bottom of the skimming basket. Therefore, my assumption is that this may be the source of the leak or at leak one of them. In the beginning, I thought it was because of tree roots from the neighbor’s tree because there are several cracks in the decking around the pool. (Hoping I am wrong).
In addition, I am confused as to what the valves are for and which ones does what. To date I have replaced all the pvc at the pump and filter, including one valve and have replaced all the filters (there are 8). I do know that we have a Hayward Progrid D.F Filter with a SP710Xr50, Challenger Ch11-N1-A1 and a Booster Pump (not used it yet or know who to). I think the pool is 25,000 gallons but not certain. I have included a picture of the valves in question.
thank you so much for your site and your assistance.
