I have a 22,000 gallon pool with the skimmer at each end.. the skimmer at the deep end is plumbed with the main drain... that skimmer has been replaced, but due to the soil being unstable, it has separated twice.. in order to stabilize the soil they want to charge me $18,000... therefore I'm wondering if there is a way to just close that skimmer off and only have the one?
