Review: Preventative without harmful chemicals - It's easy enough to use. I put a couple teaspoonfuls down each bathtub, bathroom sink and kitchen sink drains. I will wait to see if there's an improvement on the Phorid fly problem. So far, it's been a couple days and I've not been noticing any significant phorid activity. I'm certain it will work because its an Enzyme cleaner designed to remove food and biological debris that build up in drains which attracts the Phorid fly. Enzyme cleaner was specifically recommended. ## Features - Helps prevent clogs in sinks, toilets and showers - ENZYME BASED FORMULA: Breaks down drain-clogging elements.

The Liquid Drain Defense Build-up Remover is available in 64 ounces and does not require mixing. Pour 1 ounce of the Liquid Drain Defense Build-up Remover into the drain, followed by 16 ounces of warm water. Whereas, the Drain Defense powder require to be premixed. Add one scoop of the powder into 16 ounces of warm water and pour the mixture into drain. **Q: Does this dissolve toilet paper?** A: Over time **Q: Is this like the old drain care? I want to use it in the bathroom for the stench out of the overfill drain.** A: It seems to help with odor but not knowing what is causing your odor problem or how severe it is, I hesitate to say this product would be 100% effective on solving that problem. And I have no idea what “old drain care” is so I really don’t know. **Q: Is this product safe for pex tubing? I need to prevent fat buildup in my kitchen plumbing.** A: Absolutely. When used as directed, Zep Drain Defense Pipe Build-up Remover is suitable for all plumbing, including "pex tubing." Use Zep Drain Defense Pipe Build-up Remover to dissolve years of grease, oil, and other drain clogging build-up. For best results, mix 1 scoop of Zep Drain Defense Pipe Build-up Powder with 16 ounces of "warm" water and stir until treatment is properly mixed. Pour mixture into drain and allow treatment to work for 6 hours or overnight. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Toliet is now flushing better after first use!!! *by T***M on August 27, 2026* This is easy to use.

I used a very liberal amount the first night , my drains were not clogged though I was worried they were sluggish at times . Gave it a good 8 hours after following the instructions . In the morning I filled up the sinks with stoppers , turned on all the faucets otherwise and took out the stoppers sending a rush of water through the pipes . They all drained very well . So much so I believe there was improvement the first night and enough so the next few days will not be able to perform better . However as instructed this first time through I will repeat for 3 nights in a row . I use ridx monthly and have for years . I had also put down Liquid Plumber before winter each year in my pipes feeling sad I was killing good bacteria in my septic systems . Will use this stuff from now on . Took one star off for no measuring cup and fact you really seem to need to use allot at first way more then they recommend . There is no way I will get 44 applications I will be lucky to get the 3 nights times two systems or 6 heavy applications from the $12 container for the first run . After that I imagine I can use less . If I could get it down to what they recommend I would get almost 2 years out of a container ( 44 uses or / 2 systems 22 months ) making it cheap to use . I was most impressed at how it helped my bath drain . Make sure you have a bucket or somewhere to wash your hands . I have a sump pump on a sink downstairs that just pumps out on the drive but otherwise you would need a bucket of water so you would not rinse your bacteria out of the pipe washing your hands . ## Frequently Bought Together - Zep Drain Defense Enzymatic Cleaner Powder - 18 oz (Case of 2) ZDC16 - Safe for Pipes and Septic Systems - Green Gobbler Fruit Fly Goodbye Gel Drain Treatment | Killer Flies & Eliminator (1 Gallon) - Green Gobbler Enzyme Drain Cleaner | Controls Foul Odors & Breaks Down Grease, Paper, Fat & Oil in Sewer Lines, Septic Tanks & Grease Traps | 1 Gallon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/129684032-zep-drain-defense-enzymatic-cleaner-powder-18-oz-case-2](https://www.desertcart.co.za/products/129684032-zep-drain-defense-enzymatic-cleaner-powder-18-oz-case-2) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-02*
