Ever notice how rocksalt kills grass around sidewalks?

Dump a 25 pound bag in a wash tub mix hot water to help it dissolve
and try and get most of it down line, then go out for day so the salt
stays in contact with the roots kiiling them

been doing this for 10 years now with no problems, just repeat 3 to 4
times a year, to keep the roots from regrowing.

you can use rock or softener salt, it can do no harm and may just save
you the cost of a new line

my 80 foot line estimate was about 8 grand I can buy salt forever to
save that much $


Just going through this ordeal. I'd like to try the rock salt. My concern
would be that the roots are growing down from the top of the pipe and the
rock salt will sit on the bottom of the pipe. Won't make contact with the
roots causing the problem.

The salt might work if the drain were still clogged but now with water
quickly flowing out.

Unless there's some way to keep the salt in place?
