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.

This product sinks so limited applications

Would Not Recommend

This product does kill roots however if you like myself and many others have roots coming from above your backup this product flushes under them because the product sinks in water, be mindful that if you have roots from the top of the pipe this will not work, a snake or hydrojet option is best for temporary fixes until you can get the damaged pipe(s) replaced

Tree Root Killer.

This product was referred to me by a local plumber. I have not used it yet. I won't know the results of its use for several months or maybe even a couple of years. The product will be easy to apply to my septic system.

Cost is a little high but affordable.

Use it every 3 months to help keep tree roots from slowing sewer drainage. Advised to use it by a plumber.
