## Overview

The iSpring AFW43 Water Systems Feed Water Adapter is a durable, easy-to-install connector designed for cold water supply valves. Compatible with both 1/2" NPT and 3/8" compression fittings, it features push-in quick connect fittings for tool-free installation and a ceramic valve disk rated for up to 1 million leak-free turns. Ideal for reverse osmosis systems, coffee brewers, and ice makers, this compact brass adapter ensures reliable, long-lasting performance.

## Description

The iSpring feed water Adapter connects between the cold water Supply multi-turn angle valve and flexible riser pipe, to the main water Supply, for applications in reverse osmosis filtration systems, automatic coffee brewers, ice makers and many more. The included Conversion Adapter (busing) can be threaded onto either side of the valve to make the configuration of 3/8 inch x 3/8 inch comp or 1/2 inch x 1/2 inch NPT. Please read these instructions carefully before installing this product and refer to the water filter installation guide.

Review: Great way to tap cold water line - Installed to add my old filtration system directly to a sink mounted faucet. It installed very easy. The supplied adapter works great. There are no leaks. I have used the valve several times in the past few days to turn on/off the water to diagnose a leak(s) on my old filter system. Still no leaks on this cold line adapter. It feels solid. I recommend this for anyone wanting to add a 1/4" OD tubing cold water feed adapter for their filter system or other needs.
Review: Exceptional Customer Support from iSpring - Not to be confused with desertcart Services, this review is for iSpring. They deserve a 5 rating across the board. It's a quality product at a reasonable value and with exceptional customer service support. When desertcart Services botched up the order, iSpring stepped in and took care of the problem. Sadly my experience ordering it through desertcart Services was not so good. It does not mention the 1/4" quick connect anywhere on the product description. Instead it uses '3/8" COMP' description which can confuse buyers into thinking they're getting a 3/8" quick connect. It's also missing the quick connect locking clip. Don't know if it was intentional but it sure was inconvenient for the buyer. It seems like they're trying to steer buyers into ordering additional locking clips as a separate purchase. Lastly they refuse to post negative reviews on themselves which means their reviews are worthless. I submitted a 1 review on them and they wouldn't to post it. This 5 star review is for iSpring.

### ⭐⭐⭐⭐⭐ Just what I needed
*by L***R on July 26, 2020*

I bought another RO system that actually had a fully metal part that I liked better. However it was threaded incorrectly. On the supply side it was 1/2" brass threaded and I have 3/8" supply lines. A trip to both big box stores turned up no solutions. So this seemed like a great way to go. It took seconds to install and worked perfectly for my 3/8" supply line. It does have a plastic valve dial :/ but, I'm still very happy with it. I just wished I had ordered it sooner and not wasted so much time trying to figure out how to make the other part work!
