Review: Perfect product for single-drain sinks with a garbage disposal and a dishwasher. - Exactly what I needed - I have a farmhouse sink with a single drain, which has a garbage disposal. 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.
Review: No drilling needed. Super easy RO system hookup. - 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 desertcart 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.

### ⭐⭐⭐⭐⭐ Perfect for Installing RO Without Drilling Through Any Drain Pipes
*by K***R on October 9, 2025*

Clear instructions, easy to install, fits perfectly! This was exactly what I was looking for to make my RO equipment attach to a large garbage disposal under a single-bowl sink without having to drill a single hole in my home's plumbing. It's expensive, but totally worth it.
