Not sure if this is the right forum, but thought I'd start here... We have a 14x28 inground, in the NE, Sand filter, Salt generator, heat pump, etc.
Would water from backwashing be useable for watering plants? I understand there will be chemicals to some extent in the water, but wanted to get pros/cons, done this/don't do, that feedback.
My thought was to pump it into a rain barrel and use for general watering of flowers, etc. I imagine the rain barrel would need to be cleaned seasonally for sediment, sand, etc...
