I have used Roebic granular Drain Buildup Remover concentrate for a number of years to maintain clog free drains in our home. I liked it's ease of use and reasonable price. However, the last four bags I have purchased through Amazon only have about 378 grams of product (~13.3 wt ounces) vs the 454 grams (16 wt ounces) labeled on the bag. That's 16.7 % less than label claims.I have contacted the company and am waiting for a response.

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 sink
And 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. 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. 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.

Reviewed in the United States on October 19, 2023
Using this for a basement sink drain that runs slow and has regularly plugged up for years. I don't want to use harsh chemicals as I was concerned about damaging a waste injector pump. First time using this and I am impressed. After the first treatment, the drain was definitely starting to open up. Each day was much better. Today is day 4 and the drain can keep up with the water turned on full speed! Simple to use as well.

Reviewed in the United States on July 27, 2011
I had a kitchen sink that was starting to smell quite badly (both the drain and underneath in the cabinet area) but exhibited no real flow issues. The smell wasn't familiar and didn't smell like sewer gas so I guessed there was likely some buildup of food or fat in the trap. I don't really make a habit out of dumping coffee grinds or grease down the drain but as part of cleaning pans and my french press I can see how either might build up over time when I'm not being careful enough. Anyway, I decided to give this bacterial cleaner a try. As per instructions I poured the solution down the drain and let it sit overnight. The next morning I still detected a faint odor through the drain, while the cabinet still retained a strong odor. I left the doors open to air out the cabinet area and ran a few gallons of boiling water down the drain - 12 hours later and the smell is pretty much eliminated. I think I'll give it another dose again tonight but this seemed to resolve my issue quite effectively.

It doesn't really say in the product details but 1 dosage is equal to two level cap-fulls (it's a rather shallow cap) and my guess is if you used this monthly for maintenance on 2-3 drains it would last you quite a long time.

We had a slow running drain in our shower and since a friend recommended K-67, we decided to give it a try because of its use of natural organisms to clear drains. Well, we tried it three nights in a row, and absolutely NO results whatever. So we went out and for less money bought some Liquid Plumr and in fifteen minutes (per the label) the drain was clear. Maybe K-67 is just good for preventing blocked drains, but not good as a drain opener? In any case it doesn't seem to be worth the expense.
