Customer Questions & Answers

Can this be used in a cesspool, not a septic tank?

I successfully used a powdered product made by another company that is no longer sold in Home Depot. Can this be used as a preventative for a 50 year old cesspool that has never had any problems to date?
Asked by: Dave
Yes, it can be used on either type of waste treatment system

Label says Septic, Cesspool and pipe cleaner. Septic line pipes or regular clogged pipes?

Asked by: lyn25
Zep Septic System and Cesspool Treatment would be to assist with septic pipes. If you are looking for a clog remover for interior drains, we would recommend looking at one of our drain openers such as our Professional Strength Drain Opener, 10 Minute Hair Clog Remover, Liquid Heat or Crystal Heat.

I used to purchase ZEP's 16 oz septic system treatment. It is discontinued and I want a replacement.

I used it twice a year in my summer home and it was great. It allowed the 'benficial bacteria' to thrive. Does this product do the same thing? This is a liquid the previous product was granular. If I can purchase my original product please let me know how. If it is disconinuted pease provide a recommended replacement.
Asked by: Bonnie
Thank you for contacting us. We apologize for the response delay. The Septic System and Cesspool Treatment is not discontinued, and is sold at most Home Depot stores or online. We hope this helps. Thank you for selecting Zep Commercial products. Thank You, Zep Commercial Consumer Relations Team

64 oz. Septic System and Cesspool Treatment is rated 4.4 out of 5 by 11.
Rated 5 out of 5 by from Easy to use, effective and non toxic We switched to the ZEP liquid septic tank treatment after using the powdered variety of septic tank treatment. The ZEP liquid is very simple to use, you just pour it in the toilet bowl and flush it down and it starts its job of breaking down the contents of the septic tank. No residual powdery mess in the toilet bowl, just one flush and its gone. There's enough fluid to treat 1,000 gallons so if you have a 500 gallon septic tank, there's enough for two treatments here. We normally treat our septic tank once every 2-3 months as needed. It is compatible with virtually all types of plumbing and most importantly, it is non toxic according to the material safety data sheet.

Rated 5 out of 5 by from Quickly melts organic materials I used this for a completely different purpose than it is advertised for, but it worked like a charm. I had an elderly pet that had many "accidents" on my carpeting. The stain and odor were embedded into the fibers and there was still a lot of "organic matter" stuck to the material. I moistened the waste with this solution at full strength, allowed it to soak for 4 hours and then used a carpet steamer - shampooer over the areas. The solution had dissolved the waste material, allowing it to be vacuumed up into the carpet cleaning machine and leaving the entire area looking clean and smelling fresh. The enzymes in this work better for this purpose than any of the solutions sold in pet stores for clean-up. Because it works so well on organic material, I would hesitate to use it on wool or cotton-fiber carpets, but it did wonders on my synthetic blends.

Rated 1 out of 5 by from Does not work Used 4 bottles over a 2 month period and not even a tiny bit of improvement in a cesspool

Rated 5 out of 5 by from Reasonably priced alternative I have a septic system and large family which means I need to keep my system healthy and working efficiently. I have used powdered alternatives in the past to treat my septic. But I always disliked the power dust cloud that came with their use. This is a liquid form. Simply pour into the toilet, flush and done. No powder cloud to inhale. Easy to use. The bottle says it will last for 2 monthly treatments.

Rated 5 out of 5 by from Preventative Maintenance This is a good way to keep yourself from dealing with a septic tank back up. Just a few bucks and under a minute's worth of work for saving myself that trouble is well worth it in my book. Application is very easy - just flush it down the toilet. I flushed half down one toilet, and half down the other. It's supposed to be safe for all plumbing types too, so no worries figuring out if you've got cast iron, PEX, ABS, or PVC. The jug holds 64 oz of treatment, which is enough for a 1000 gallon septic tank. If you've got a 500 gallon tank, it will last for two applications. There's a press-and-turn child proof cap for storing the rest safely, and there's also a tamper evident safety seal under the cap. The jug pours well too - no drips ran down the side at all. There's a faint bit of odor, but it doesn't really smell much at all.

Rated 5 out of 5 by from Preventative treatment This advertises as a non-toxic formula that won't harm pipes. It is a large 64 oz. container, good for two treatments. Directions state flush down toilet every two months (32 oz. for a 1000 gallon septic tank.) The bacterial enzymes break down grease, paper, fats, proteins, and starches which will protect your system from backing up due to clogs. It is very expensive to dig a new drainfield so this product is worth buying.

Rated 5 out of 5 by from Hmmm,,what to say about that! I mean this is a tough review to write. I have been using septic treatment for years. You add one half of a bottle of this product to your toilet water and flush. From there if everything is working right you never have to deal with a backed up septic system. Been there, done that and it really is not something you want to happen. So use this product every two months and that should prevent any trouble.

Rated 4 out of 5 by from Large bottle means lasting value I used the 64 oz. bottle of Septic System and Cesspool Treatment as recommended by the manufacturer, I poured 32 ounces in the toilet and still have another 32 ounces to be used in 2 months. 2 equal treatments will achieve a prolonged septic system and cesspool treatment period. This product gives me greater long term security that the septic tank system won't overflow.
