I know there must be a limit on the size/length of the discharge hose on my softener, but not sure where to find the info ???

Can I get away with about 60 feet of 3/4 inch hose ? Will this present too much back pressure for the softener to work properly ? the hose would be below the level of the softener the entire distance..., or should I find a way to run a 1" PVC drain line ?

Thanks guys!
