Frequently Asked Questions About RootX Foaming Root Killer

How often do I need RootX treatments?

You should treat your sewer lines or septic system every year. Ask your plumber to send in the RootX registration card, and we’ll send you a reminder after 11 months that it’s time for your annual RootX treatment.

How long does it take the RootX foam to dissipate after application?

The fast-acting RootX foam will normally dissipate in about 15 minutes

Will the RootX foam stop or block any flow during application?

No. RootX foams on contact with water, and it uses the natural flow of the line to spread the foam throughout the pipe. Wastewater continues to flow under the foam, so using RootX does not cause any service interruptions. However, you should reduce water use for at least an hour to allow the RootX foam to fully spread and soak into the roots.

Is RootX hard on pipes or septic systems?

No. RootX contains no diquat dibromide, copper sulfate or metam sodium. The RootX formula is non-caustic, non-fumigating and non-systemic. RootX also promotes bacterial growth, which is good for septic systems.

Can RootX be used in septic systems?

Yes. RootX can be poured directly into the septic tank and distribution box to kill roots that have intruded into the tank and drain field lines.

Does RootX harm trees and plants?

No. RootX only kills the roots inside the pipe and prevents their re-growth. Since the RootX foam only flows through the pipe, it has no effect on roots outside the pipe.

Is RootX harmful to the environment?

No. The RootX formula is non-caustic, non-fumigating and non-systemic. It is classified as a General Use product by the Environmental Protection Agency and is registered for use in all 50 states (EPA registration #68464-1). In addition, RootX carries the signal word CAUTION, the lowest chemical hazard rating according to the ISO 3864-2 standard for hazard severity panels.

What kind of chemicals does RootX use?

RootX kills roots using Dichlobenil, a proven aquatic herbicide. RootX also contains degreasing agents that strip away the grime on roots, allowing the Dichlobenil herbicide to penetrate the root ends. Unlike other root control chemicals, RootX contains no diquat dibromide, copper sulfate or metam sodium.

How quickly can I expect results with RootX?

RootX kills roots on contact and destroys the root structure within the first hour after application. The roots decay in over time depending on the type of plant and the size of the root mass. In extreme cases where the pipe is completely blocked or close to it, your plumber should use mechanical root cutting to clear the blockage, followed immediately by RootX to kill the remaining roots and prevent re-growth.

How long does it take to apply RootX?

Your plumber can treat your sewer or septic system by applying RootX in a cleanout or pouring it into a toilet. It takes just minutes to complete a RootX treatment.

What’s the best location for applying RootX?

The cleanout is the preferred method for most residential applications because it’s closest to the pipes where roots can cause problems. If there’s no cleanout at your house, your plumber can apply RootX using the toilet. To prevent foam overflow outside the pipeline, he should only use a 2-lb. jar of RootX in a toilet application.

Should I use RootX together with mechanical root cutting?

If this is the first time you’re having your pipes treated or if the pipe is completely blocked, your plumbing contractor can clear away the immediate blockage by cutting the roots first. Then he’ll use RootX to kill the remaining roots and leave a barrier on the pipe to prevent re-growth. Make sure your plumber applies RootX within one hour of cutting the roots; this ensures the remaining root structure properly absorbs the RootX herbicide. Otherwise, he’ll need to wait 6-8 weeks before using RootX to allow root ends to develop.

How is chemical root control with RootX different from mechanical cutting?

Treating pipes with RootX takes less time than mechanical cutting, and the results last longer.

Mechanical root cutting leaves some roots behind in the pipe. Cutting roots is also like pruning a tree; it stimulates vigorous re-growth in the remaining roots. That means new root growth can fully clog your pipe again in just nine months. What’s more the cycle of cutting roots, re-growth and cutting again will eventually destroy the structural integrity of the pipe.

RootX kills roots on contact; the dead roots decay over time and are carried out with the flow of the pipe, restoring the pipe to its full capacity. RootX also leaves a barrier on the pipe walls to prevent future root growth. Once you’re on a maintenance program with annual RootX treatments, you should be able to eliminate mechanical root cutting in most cases.

Is root intrusion a serious problem?

It can be. According to the Environmental Protection Agency, root intrusion is probably the single most destructive element involved in maintaining a wastewater collection system. Left untreated, roots will spread throughout the pipe. Material passing down the drain gets trapped in the roots, restricting the flow or even causing a complete blockage. Root intrusion can eventually destroy a sewer or septic system, costing homeowners thousands of dollars to repair or replace.

How do roots grow in sewer pipes?

As trees and plants mature, their underground root system grows and naturally seeks out moisture. The most consistent source of moisture is sewer and wastewater pipelines. Joints and cracks in the pipe create natural entry points for roots. Roots start to grow at the top of the pipe and spread.

What is the shelf life of RootX?

If RootX is stored in a dry room temperature environment the shelf life is 5+ years.
