I have had my pool 27 years trouble free. For chemicals I just used chlorine and did not worry about the balance of the rest. This year Superior, Nepean On opened it up. Never used them before but now I have the scum and foam plus water leaks at the filter which they created. Had to get my own plumber in to fix it. They have left me stranded as they only have voice mail and never respond to it. Now what do I do?
