It's cheaper than the price of snaking my line.

Plumbing Maintenance Must Have

Would Recommend

Last year a tree root blocked one of our underground pipes. This ultimately lead to a gray water backup in our kitchen. Unfortunately that section of the pipe had to be replaced. Our plumber recommended we purchase this product to prevent any issues moving forward. This product is very easy to use. It is now part of our seasonal home maintenance.

Not sure if it works, but it does not make things worse at least. Flow seem to be reasonable with the product

Root Kill for Septic System

Would Recommend

I liked that I did not have to stop the water flow to use this product. After 1 week, it is appearing to work. We are still waiting to see if it improves everything after 4 weeks like the bottle said.

Recommended by my Aerobic service company

Would Recommend

I have used this product several times. After the first application, the roots in my Aerobic system were gone. I will continue to use it, to help from getting new root growth.
