how do I get rid of roots in main line?

ok I have had a problem with roots in the main line of a rental house twice now and both times I have had to call in a pro to cut them out, so now I want to make sure they dont keep coming back.. So what else can I try besides the root killer for main lines I buy at lowes???

Bad news. I have never seen anything that will permanently kill roots or stop them from growing back into the line. You probably have cast iron pipe for drain lines. PVC is more root resistant as the outside is smooth and the roots go around it. The drain now has holes in it and eventually you will end up replacing it. You could remove the trees, replace the line, or have it augered once a year. You can rent the commercial rooters and they usually come with 2 or 3 end attachments. One of these is a root cutter. Looks like a round sawblade. Good luck.

Do you have a terra-cotta main sewer line?, if you do there isn't anything that will solve your problem except total replacement, its going to be a on going problem. Sorry.

run a snake throught the pipe, assuming it hasn't collapsed anywhere, then use a cutter bit apx the same size as the inside of the pipe. that should clear it . then apply a copper sulphate based product designed for killing roots in pipes.
regular applications will be needed from time to time. if the property is owned by you, it may make more sense to do what shak and dragon recomended.
good luck

There are some products you can dump into a cleanout that will kill roots in a line. But they are commercial products and I am not sure if they are ok for use in a municipal sewer system. I have used them on our system at work, but its all our system. I do not remember the name, but its from State Chemical. It comes in a 5gal bucket as a granule.
