Question 1

Is this just copper sulfate which can be bought pure for much less?

Accepted Answer

I think Robert has a good idea there.But, I checked on ebay and the Copper Sulfate Pentahydrate 99% was $10/pound, the same price as this product (now $20 for 2 pounds). So it works out the same cost wise.

Question 2

compare to Roebic FRK-6 Foaming Root Killer, Which one is better? Thanks

Accepted Answer

I really don't know the answer.  I've used the other Roebic root killer because we have a long standing problem with roots from a large tree fouling up our plumbing and causing back-ups in the sewage line to the street.  I've used it for years and didn't even know about the FRK-6.  My off-handed guess would be that the FRK-6 would be great to blast through a tangle of roots with and the K-77 I use is more of a preventive measure.  I started using that after I'd spent $$$ having a "roto-rooter" guy ream out the sewer line for the umteenth time.  I probably wouldn't hesitate to use the FRK-6 if I had another blockage in my line.  I use the K-77 every six months and haven't had to resort to calling a plumber for several years since I started using it.

Question 3

Has anyone had experience using this product on a slow moving drain WITHOUT having their drain augered?

Accepted Answer

I use that stuff every 3 months 1/3 of a bottle, now I augered my drain because mine had really backed up but I won't stop using this stuff, I haven't had to do anything else with the drain so I imagine it is killing all the roots from growing any further. It's definitely worth a try, I've got a friend within the family that does plumbing and he told me that is about the best on the market!

Question 4

Is this safe to use in a Septic System without harming the septic mound which is about 200 feet from house?

Accepted Answer

I have used it twice in the past year and to my knowledge there has been no damage to my septic system. The product worked very well.
