The best way to drain water out of a pool is through a 1 1/2" waste line. If you have a filter with a multiport valve, you probably have this feature built in as one of the valve mode. But if you have a cartridge filter you may not have this feature and you may be spending hours draining your pool with a garden hose. This guide shows you how to add a valve and 1 1/2" hose to drain your pool.
