I'm also thinking about switching to salt and am very close to buying. However, a couple friends of mine have killed grass and other plants with the backwash. They were both able to alter their discharge area to reduce the effect. With the slope of my lot and being surrounded by other houses, I'm pretty much limited to the back yard lawn.
Has anyone had the same problem? Any tips on how best to deal with backwash from a salt pool? Thanks for any insight.
