I am plumbing my own pool, this will not be the first pool I did my own after the shell was sprayed. The main drain and Spa drain are 3" diameter. I am planning to reduce them to 2" to match the rest of the system. Has anyone ran 3" and why did you? The Pool/Spa together are 32' x 20' with a 7' sundeck. I am planning two pumps. Thanks
