Zep Drain Defense Pipe Build-Up Remover - 64 Ounces - ZLDC648 - Professional Strength Liquid Pipe Build Up Remover,GREEN

This product was recommended by a plumber that was clearing my kitchen sink drain. I now use it every month and the flow has stayed great. Only use 1 oz as directed for best results.

Our first purchase of Zep Drain Defense was then called Drain Care. We used it on a slow draining kitchen sink and it worked great. Fast forward to late 2024's stubborn clogged toilet. Plunged it, then snaked it, and realized the clog was much deeper in the system. Resorted to Drain Care. It worked overnight by pouring 8 oz. then flushing once and leaving the toilet alone. We used it two more nights in a row and the toilet ran as if new.Drain Care is no longer available but Drain Defense and Drain Care are basically the same enzyme-based product. We have since used it in all our sinks, drains, and toilets. This house is 25 years old as is the septic system. We have PVC in our plumbing and minerals in our well water. I would much rather use Drain Defense on a maintenance basis then resort to caustic acids. However, how well it works depends on either what is clogging your sink/drain or how extensive the clog. Zep makes other products suited to complete clogs or specific types of clogs. If you've never done any maintenance on your drains or the history is unknown, this may not help. The 6 hour window is due to the enzyme effectiveness-- leaving Drain Defense overnight or a week won't increase results. This product is probably best when you still have water draining.

We’ve been using this drain cleaner as a regular maintenance product for the older pipes in our new place. While we haven’t had a clog to test its strength on, the fact that we haven’t had any issues so far feels like a win—especially in an older building. We're hopeful that continued use will help prevent any major problems down the line. It’s easy to use and gives us peace of mind.

So far we've only used it once but so far so good.Our washing machine empties into the utility sink in the laundry room. Even with a hose filter and a mesh drain filter, this drain often slows down to the point that if we wash a large or xl load the water can't drain as fast as it's being pumped in and occasionally over flows. We hate putting drano down too often so I was looking for a good maintenance product. After 1 application of this, the pipe has continued to have a great flow. We will use it every month now to keep it in great shape.

The media could not be loaded. Very disappointed, didn't work at all, used half the bottle at one hour intervals.Normally I would not return and accept the loss, but it was quite expensive compared to other drain cleaners.I suppose this would work for maintenance but I would not recommend for any clogs.We just had a slow drain clog, it didn't even make a dent in it.This video is after multiple tries.

This didn't work on my drain clog. I was hopeful as it had so many great reviews. It would probably be more beneficial for drain maintenance but not for a nasty clog. I might use again but for a different purpose. Ended up having to buy a different drain clog remover.

Will not harm your pipes. ⭐️⭐️⭐️⭐️⭐️👍😃

Nothing was helping our sinks drain better/unclog. Used it once and our sinks haven’t had issues since with taking forever to drain and water just sitting there. So happy to have tried this out.
