WE had a little gray water problem bought house 3 years ago only recently moved in permannant had tank pumped then ten days later water showed up around tanks company advised nothong to do with pumping but fieldlines have put root killer in and main line cleaner how long before I know if effective and also have had a lot of rain with already wet soil how long will it take to normally dry out

If your issue is in the field that root killer isn't going to do much at all. How old is the field and what is the size of your family and the size of the tank. Did you have an inspection or a perc test done before purchasing?

Root killer doesn't remove roots it simply kills them. The way it works is that we snake the lines and auger the roots out and then use root killer to control the root growth. If you have roots clogging your drain field then you could snake from the septic tank manifold to clear the lines and then use root killer or simply move and reinstall a new drainfield. Good luck, Tom
