Zep Root Kill - 2 Lbs (Case of 4) ZROOT24 - Root Control in Septic Tanks and Leach Lines

Been using for few years in sewer line. Helps prevent expensive plumbing service call., so far!

i put this copper sulphate into my clean out next to my house last month. Since then my mainline is draining very slow. I wonder if this thing is blocking my mainline.1/14/21 Thank you ZEP for super customer service in explaining how this root killer work. I had use this product for more than ten years already because my neighbor has a giant tree at the fence line and refuses to take it down.This year is the first year the mainline was blocked after application. I guess it is more effective this year because it had coated my whole mainline for a month. I don't have to use foaming root killer. I had put in 3 gallons of instant power, 2 bottles of k97,and 2 gallons of Green globbler to dissolve the dead roots. Today I have to snake it. There is no resistant whatsoever. My cobra snake goes in real easy. No blockage and no dead roots in return. Then after two loads of laundry , the line is all cleaned and running like a stream. Thanks to ZEP ,all mainline cleaner , and cobra snake companies!!!!! They all have very good customer services. I save $500 dollar and the hassle of hiring a plumber.

Used in my septic tank and fieldline to combat a red maple tree. The wet patch seemed to dry up after about a month from treatment. I will buy this product or maybe try another just to see if I can keep from digging up my fieldline.

This works if you follow the directions.

It works!

I started using this several years ago due to clogged septic lines and it was working within 2 weeks. My septic lines started leaching and I use 1 bottle quarterly. Great stuff.

I use it on a regular basis.

As far as I can tell, Zep Rootkill is working. No roots in sewer line. Also, the salt bush in the leechfield has died. So far, I am hopeful. I'll let you know if things change.
