ET116-001 Drain Line Adapter (DLA) With 1/4-inch Quick Connect Fitting for a Water Filter and 7/8-inch Fitting for a Dishwasher

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.

Used this to connect reverse osmosis drain to disposal dishwasher drain

This part does exactly what it's supposed to do. It's sturdy and seals up easily. Very nice having the ability to choose the diameter of your dishwasher drain hose. Mine was 3/4" so I just needed to cut it at the 3/4" line. Easy and reliable. An excellent American made product.

Works well!

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.
