Question necro, but I'm not sure if it really works or not. We have a greywater line that still gives us fucking grief, and after using a ton of rootkiller it alleviated it...a little bit...to the point that it was useable but it would still drain slow. Until the other day that is, when someone (not me) decided to wash some cat bed (blanket?) or whatever the fuck without vacuuming the fucking cat hair off first, so now the fucking washing machine backs up every time it drains and now you literally have to stand guard while doing laundry so you can stop/start the drain cycle before it overflows. Which I forgot about this morning so I just had the pleasure of having a"Why did you let it overflow?"discussion. I'll probably just have to bite the bullet and go rent a snake tomorrow.Speaking of cleaning drains. Anyone here have experience using a root killer to keep roots that have breached a sewage pipe at bay? Wife and I had a minor sewage backup we caught before it got bad this weekend. Had a plumber come and snake it out but we'd like to perform preventative maintenance for a few years until we decided to get a new line run.
I have no idea if the drain has collapsed, is plugged fully/partially, if it is tree roots or not...so maybe the metric fuckton of root killer I used (twice) does work but there is some other fucking issue...or i it is just roots then that shit is completely fucking worthless, but I'll find out when I snake that motherfucker I guess.
