Roebic Laboratories K-67 Granular Concentrate Drain And Trap Cleaner, 16-Ounce Bag

FOR ME AND MY BOYFRIEND THE SAME THING HAPPENED AS THE BELOW REVIEW:In my case, we also used a snake to remove the majority of the debris and much of it was hair and grease as well as plant fiber that had gotten past the sink garbage disposal under the sinkAnd the Dran-O that we had been using had not completely dissolved the hair and flushed out the pipes.Once that happened we used about a 5x dosing after flushing about 10 gallons of water down the system to help provide physical removal and moisture. And the best part about it was it didn’t seem to damage our pipes.I AGREE WITH THE BELOW REVIEW“A further investigation of the pipe revealed that soap and fat buildups were clogging what turned out to be a 20+ foot horizontal run from the sink into the main sewer pipe. After a physical removal of the vast majority of the blocking material, I utilized the K-67 product to help move out the rest. Cautionary note: A standard dosing of the K-67 is not sufficient if you have a longer run to the sewer pipe as the mixed enzymatic liquid will simply not be in enough quantity to deal with the material at hand. I currently use about a 10x dosing after flushing about 10 gallons of water down the system to help provide physical removal and moisture”.I agree with the below review:ORIGINAL POSTED REVIEW:I was experiencing a backing up/slow draining of my kitchen sink and Drain-O wasn't cutting it. A further investigation of the pipe revealed that soap and fat buildups were clogging what turned out to be a 20+ foot horizontal run from the sink into the main sewer pipe.

I currently use about a 10x dosing after flushing about 10 gallons of water down the system to help provide physical removal and moisture. This has worked greatly to keep the pipes clear and the drain running optimally. Also, even while using a higher dosing to cover more ground, the product size is still plenty sufficient to last a long time. I normally treat the pipes with this once every month, give or take. I have been very pleased with the results and the enzymatic process should be much safer all around compared to using a NaOH method.

It works great. You just have to follow the instructions at the local hardware stores and other local locations. You can’t find it sometimes people figured it out so I had to order it.

This product , after years of use , seems to do a very good job on keeping the drains clear.

I use it once a month.
