Our pool is set to be re plastered and we were told we needed to add a second main drain. We currently have one drain and our pool is over 40 years old. I know we could probably argue that this was built before the Virginia Act now requiring two but should we add the other drain? Does it make a big difference/worth the money? Can I just get a really good cover or do something else to help the suction of the one drain? We have two skimmers.
