Anyone have a preference to root killers as used to stop intruding roots in sewer lines. How about the foaming root killers that fill the line with foam and deposit a root killer product on the inside of the line that is supposed to keep roots from intruding for up to a year. I have one particular spot that get fouled with roots anywhere from once every 6 months to once a month (depending on growing season). Thanks Pat

Copper sulphate has always worked well for me.
Thanks Dan; That was the 2nd thing I did after clearing the line. Regards Pat
