Need help finding hose adapter fitting

Jl330 · 2026-10-08T10:03:48-0400

Setting up a new ro/di unit. The input is a garden hose attachment. I’m trying to connect to a former washing machine hookup. I had assumed they were the same thread but I guess I was wrong. Does anyone make an adapter for this? Can I get it at the hardware store or need to order it?

Do you have a photo of it?

Usually washing machines use a standard 3/4" GHT fitting just like the RO unit. Is it leaking? You might need to add an o-ring (maybe borrow one from your garden hose) or even thread tape if it's just a drip.

Or maybe you have an odd washing machine hookup.

I can’t even get it to thread on

Would you be able to provide photos of the hookup? Something is odd.

I think the threaded adapter from my previous setup is actually just stuck in there and I need to somehow get it out. Silly mistake.

Washing machine hookups are the same thread as a garden hose. I'm at my shop this morning. Here is a picture of the washing machine hose hooked up to a standard hose bib.
