Product Description

For sewer and septic tanks; Naturally breaks down waste; Digests paper, fats and grease in main sewage lines.

From the Manufacturer

K-97 is a beneficial product for a variety of plumbing areas. The main line in a home going to either a septic, cesspool or municipal system tends to accumulate sludge that can cause major back-ups in a home. Main Line Cleaner, containing millions of specialized waste degrading bacteria, keeps this major line clear and flowing. K-97 is indispensable in resolving the problems of sludge build-up due to the inefficiencies of "low flow" toilets by keeping the sewer pipe clear. Undersized septic systems have an increased flow rate that can cause many problems in a leach field. By using K-97 on a weekly basis, the retention of waste degrading bacteria increases the efficacy of the smaller, overworked systems

After plunging and plunging I decided to give this stuff a try. I was very amazed by the next morning my toilets were flushing and drain line was flowing. I was just about to call the septic tank pumping service. I don't know how long it will last but it sure is working for now

K-97 bacterial drain cleaner is an excellent product. I have used it both in my house and in an 8 unit apartment building that I used to own on the main line.

Its easy to use:
Just pour 1 quarter of the bottle (8 ounces) into a toilet and flush. Do this just before bed so that the cleaner stays in the line for while without being washed or flushed out by further sewer line usage. That is all there is to it!

This stuff really works:
The house was build in 1916 and the systems are very old. We had constant problems with the main sewer line backing up, creating a mess in the basement. We snaked the main line a dozen times in a year, and the problems kept coming back. I decided to resort to the Roebic bacterial cleaner because it would not damage the pipes like chemical cleaners. The bacteria will eat away the potential clogs but won't harm metal or pvc pipes. To clean out the line after the latest snaking, we did 4 consecutive treatments on four consecutive nights (1 bottle is enough for 4 treatments). After that, we have been following the recommended 1 treatment once a month pattern for the last 4 months, and have not had any further issues with the sewer backing up.

I also used this cleaner to keep the main line in my apartment building running clear. I owned the building for 4 years, and I would run 8 ounces through every other week to keep the main line clear. Again, this was an old building, I liked that the bacterial cleaner would eat away the potential clogs without risking damage to the old pipes posed by using chemical cleaners.

The K-97 is designed for use on a main line, but it worked very, very effectively on my kitchen sink line.

It is an older home, and as the foundation has settled some of the pipes have a different pitch than they were when originally installed.

The kitchen line runs down to the basement and then over to the main line out. Originally, the line ran straight down and then did an almost "L" and had a slight decline to the main line. With settling, it does a more than "L" and has to go slightly uphill to get to the main. This means that even the small amount of grease from the dishwasher, rinsing the last little bit off of plates, etc. gets trapped down below the concrete of the basement floor.

The K-97 worked like a champ and cleared it out.

Five years ago, I had to call in a plumber to rotor out the clog at the cost of high three figures, but for less than $20 we were able to self correct the problem this time.

I highly recommend this product!

In service,

Rich

I have read the other reviews and for the most part, people are commenting that the product "didn't work" - well, this is a preventative product, meant to assist with the accumulation of sludge - it is not meant to clean out a main line of debris, etc. Having said that - I purchased this to assist with keeping my main line free of sludge, which accumulates in my pipes due to the use of a low-flow toilet. Seems to do the job, I plan on using it 2x a year as directed.

All my sinks and tubs drained very slowly so I decided to try this. The instructions states that you should apply 8 oz a day over 4 days. You pour it in the toilet and flush it and leave over night, avoiding using the water. I was ready to do this for 4 days but after the 1st application, all the sinks and toilets drains normally again. I will still apply it for another 3 days but I am so happy with how effective this is. Highly recommended.

Was having problems with a central air conditioner condensate drain line plugging where it joined a toilet drain. Contacted Roebic to ask about the best product that they had for this problem. Was transferred to a microbiologist who recommended four treatments with this product. Problem solved. Just ordered some more for maintenance.

We had slow drains in our older house and when we used this Main Line Cleaner the slowness cleared almost immediatley. Have purchased this several times and would recommend this product.

I stumbled on to this product--was having trouble with a second bathroom toilet that just kept overflowing. I used a closet router first, and that helped. Used 8oz. doses of this stuff for a few days in a row (until the whole bottle was empty) and the toilet is now working better than I can ever remember.

It's the only product that I found that is recommended for use by those customers on city water/sewer. All the rest of the products are just for septic systems.

I think I will use a bottle of this stuff once a year as a preventive measure.
