Thus, there was no safe way to install a drain saddle for my new RO system. This allowed me to use the dishwasher drain for the same purpose. Clear instructions, functions exactly as advertised. Fits well with no leaks. ### ⭐⭐⭐⭐⭐ No drilling needed. Super easy RO system hookup. *by on Reviewed in the United States April 19, 2025* I used this to connect a reverse osmosis system under my sink. The system only came with one of those drain saddle adapters that require drilling into the drain pipe. I’ve got a garbage disposal, and after a bit of research, I learned those aren’t recommended with disposals.Found this on Amazon and it worked perfectly. I was able to hook up my dishwasher and run the water line for the RO system with zero drilling. Everything connected smoothly and securely. Install was quick, maybe five minutes. No leaks, no hassle.If you’re installing an RO system and want to avoid drilling into your pipes, this is the way to go. Simple, clean solution that just works. ### ⭐⭐⭐⭐⭐ Works as described, clean install, would buy again. *by on Reviewed in the United States February 4, 2024* I bought this to relocate my reverse osmosis drain line since the noise of drain water falling/splashing was annoying (tough life, I know). The product feels well made and I like that this particular product stated that it was made in the United States.Install was easy and all parts that are needed are provided.The solution to my problem was partly this product but also adjusting the slope of my drain pipe from the garbage disposal to the drain stack. The slope was too steep causing the drain water to fall and splash, causing the audible drain noise.Even if I didn’t have the drain noise, I like this product for the fact that I wouldn’t need to drill a hole in the sink drain pipe for the R/O drain tubing.My recommendation? Buy this thing even if you don’t have drain noise. It makes for a very clean install of an under-sink reverse osmosis system! ## Frequently Bought Together - Drain Line Adapter (DLA) With 1/4-inch Quick Connect Fitting for a Water Filter and 7/8-inch Fitting for a Dishwasher (ET116-001, D-25QC, DLA-D) - Home Master TMAFC-ERP Artesian Full Contact Reverse Osmosis System, 7-Stages, Patented 2-Pass Alkaline Remineralization, Fast 4.5s Fill Rate, 1:1 Waste Ratio, 8.5” Catalytic Carbon, 5-Yr Limited Parts --- ## 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.uk/products/305583558-drain-line-adapter-dla-with-1-4-inch-quick-connect](https://www.desertcart.co.uk/products/305583558-drain-line-adapter-dla-with-1-4-inch-quick-connect) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-01*
