Roots in six-inch main sewer line
We do not do a lot of this work. So I'm looking for advice on how to direct my customer best.
We have spent approximately 20 man hours using Ridgid 750 with root cutting heads also video And taking pictures of the problems.
Two separate days, yesterday's video shows six joints where the roots are growing through, when it hits the seventh camera will not past that point. The first day we only got past the third. Pipe is Clay and I can see from videos and pictures we have substantially removed a lot of the roots.
I have already told the customer the only permanent solution is to replace the line (they are getting prices from subservice companies). Has anybody got good experiences with chemical treatment ? If so can you recommend a brand ?
I am reluctant to suggest jetting the line, if the drain were to collapse, it becomes a dire emergency and the company that manages the building are good customers of ours.
Also has anybody had good experience with the sleeve that you pull in the line. We do not own a jetter and we would not attempt to install the sleeve but the management company relies greatly on us for device.
The trouble with an Internet search is a lot of the time it's a sales pitch and I have no way of knowing how good it actually is.
