First post on here, I just bought an older house built in the 70s with a pool from the 80s or 90s that needs work. First im not getting enough suction when i hook up the vacuum so i have dirt on the floors, My pump is louder than a boeing 747 and there are some valves that i dont know what theyre for. There is duct tape on some of the piping as well.. I think i should replace some of the piping, newer pump maybe and im not to sure what else as this is my first pool. Any help would be greatly apprectiated, Thank you!!
