Rehabbing 20X40 vinyl pool. One Pool company said i dont need main drain remove it. The other said its the only way to cirulate water in deep end. Not sure depth of deep end maybe 8- 9 ft. I have 2 skimmers and 4 returns. leaning towards no main drain due to cost savings Any thoughts? will i have trouble keeping pool clean/clear without main?
