## Description

Product Description 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 From the Manufacturer For over 50 years Roebic has developed high quality products engineered for optimum performance targeting specific problems and troublesome areas within the septic system. Trust Roebic. The Septic Professionals, for all your septic and drain care needs.

Review: Using For Rehabbing 1960's Townhouse Drains - (skip ahead to SO WITH THIS PRODUCT if you have better things to do then relive a 1980s crutchfield catalog with this review) Purchased several bottles of this Main Line Roebic to Rehab several Drains in my "new to me" c. 1969 Townhouse. Over just 2 months living here, I've noticed a lot of Plumbing Company Trucks coming and going in the condo complex. Previous owners of my unit were not exactly maintenance conscious. The place was disgustingly dirty, and I had to replace HVAC, water heater, all appliances, $10K in flooring, and a badly rotting patio fence. And then a same building neighbor told me that the drainage plumbing in our complex is not the best. It's like spaghetti in some places, and the complex installed low flow Loos years ago. Thus the plumbing trucks spotted around every week. The trucks all have bright, cartoonlike graphics so it's impossible to NOT see the trucks. SO WITH THIS PRODUCT, I'm Rehabbing the main drain line first. The main drain line is a shared line / shared with with a neighbor who's usually out of town for weeks at a time. It's crucial that the neighbor's gone, if I wanna ensure nobody flushes for 6 hours. So on the shared wall drain, I've been doing a 1/2 bottle in the loo, every night or every other night. That's to hopefully clean out our shared drain for 2 Bathrooms + 2 Kitchens. I usually let it sit 6-10 hours total. 1/2 bottle might seem like overkill. But 2 households using a shared line is A LOT of stress on the line over 55 years. After 1-2 treatments of 1/2 bottle per day,... I'll probably cut back to 4 treatments per bottle. IM HOPING this will help clean out our shared wall drain, and whatever's between our front doors to the main underground city sewer line. AFTER SPENDING WAY TOO MUCH TIME skimming over all the products on desertcart, Roebic seems to be the top tier or top 2-3 products. IT'S HARD TO KNOW FOR SURE what's happening inside drains you cannot see. But a good number of reviewers are saying that plumbers dig this brand as one of the few that works. I'd rather use what the plumbers use, and not have to play a plumber $300 + potential damage to walls and floors. SEPARATE FROM THIS PRODUCT, I'll be using 3 $20 bottles of Roebic soap blaster. First bottle for the kitchen drain which is kinda slow. Am I the only person who drains grease into jars? When the prior owners of your new place neglected proper maintenance, it's a good bet they never took those extra steps. Second Bottle will be for the Laundry Wall Drain. Laundry drains always back up when you don't drain into a nylon capped hose, into a separate utility sink. When I have a side sink to drain into, the nylon always clogs up within 2 weeks. THAT'S A LOT IF LINT. Third Bottle will be used on my shower, which is part of the shared drain I rehabbed first. It's been stubbornly slow and I'm hoping this will Altogether, approx $100-$120 worth of Roebic for an inaugural treatment cycle. To put my mind at ease given the brightly colored plumbing trucks drama. Hopefully I'm doing this all in the correct order. I already went through 2 bottles of the Drano for the Kitchen sink and Shower, and it didn't do enough.
Review: Beyond a Good Product - OK Went through 64oz of Professional Drano, Drano Gel, and 2 Generic Brands. Nothing changed. Toilets backed up and nothing was moving. I have a 4" PVC outside the house to my Septic Tank. I can easily see water flow. Put 1/2 bottle into my shower drain, and guest shower drain. Let it sit overnight with nothing being used, NO WATER. Then this AM gave it a test, WHOOOSSHHH whatever was clogging my pipes is gone. Went to every toiled and flushed TP to I can see it come out, all 3 came out and flowed free. I think not flushing the Roebic K-97 ,and pouring it onto the shower in each bathroom and allowing it to work overnight did the trick. I sure hope I didnt jinx myself by saying amazing this product worked. Fingers crossed.

## Questions & Answers

**Q: older home and my main line has backed up 4 times recently paid plumber to pressure jet it out. Will this work ok on regular sewer line? any help? tu**
A: My house is 90 years old and I've had trouble with the main line backing up into the basement shower. I had it rotored out once or twice a year, but then finally hired a plumber with a camera on his line. It turns out the the poorly laid garage foundation (from the 1970's, now cracked) allowed a lot of water to erode soil underground and the pipe had dropped down and formed a "belly," where waste would accumulate and have to try to flow upwards to the riser. The plumber recommended that I use a product for septic tanks, adding a small amount to a toilet in the upstairs once a week to keep waste, grease, soap and paper digesting.  A year later, I've had no problems. And from what he saw with his camera, he thought that there were never tree roots in the main line. If fact, it seems to be made of metal, not tile. You've gotta love old houses! And hate them, too, sometimes.

**Q: do you put it in all the toilets in the house or just one (for prevention/maintenance)?**
A: I only put it in the toilet farthest from the street.  But that is also the one with the clogging problem in my house

**Q: Will this help keep my toilet from "gurgling" when the washing machine drains and spins ?**
A: Probably not.  More than likely you either don't have a drain vent or yours has become clogged.  If you have them, they usually are sticking up out of the roof.  You can simply dump a gallon of water or bleach/water mixture down them and they will clear up.  If you don't have them, you would have to add them to stop the gurgling.  This product cleans out the crap that has been building up in the drains...it does work...slowly (most safe products are slow), but it does clear the drain.  (the fast stuff ends up eating away your pipes)

**Q: 3 story house 3 toilets.
Do I put it in all the toilets or just one, please?**
A: I have a 2,300 sq ft house with 3 full baths and I just put it in one.

### ⭐⭐⭐⭐ Roebic and Scott Rapid Dissolve paper will do the trick
*by G***D on January 3, 2026*

I can’t tell if it’s working but my drain is working ok. I have to recommend using only Scott Rapid Dissolving RV toilet tissue. I used to have clogging issues in the mainline but between the Roebic and this type of Scott RV tissue, I’ve not had a problem in over 5 years. If you have an older cast iron mainline, this combination will definitely help you.
