We moved into a house in December with a pool, so this is the first exposure I have to pool maintenance. We don't have the pool open yet, but one thing I noticed is the drain plug for the Hayward Pro Grid filter- this sits right next to the house, so when the filter is drained, all of the water will run out right next to the foundation. Maybe not much comes out, but it sure looks like the filter holds a lot of water....does anyone have or know of some type of drain valve that you can attach a hose to so you can drain the filter well away from the house? The current plug is 1.5" MIP with an o-ring. I can't find anything that looks like it would work. Any advice will be appreciated.
