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 ### ⭐⭐⭐⭐⭐ Review *by F***K on April 15, 2026* ### ⭐⭐⭐⭐⭐ Review *by V***A on April 11, 2026* ### ⭐⭐⭐⭐ Review *by B***P on February 22, 2026* ## 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.us/products/129684032-zep-drain-defense-enzymatic-cleaner-powder-18-oz-case-2](https://www.desertcart.us/products/129684032-zep-drain-defense-enzymatic-cleaner-powder-18-oz-case-2) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-11*
