The Watts IntelliFlow (tm) product line has just undergone a modernization to make IntelliFlow (tm) truly more intelligent!

New washers often have features that utilize chip technology, digital and led displays that are designed to constantly function and/or display; even when washing machines are in their "off" mode. New washing machines are designed so that they require and allow a constant but tiny trickle of electric energy to flow to this type of on-board circuitry.

First generation IntelliFlow devices were originally designed to only recognize electrical current as fully on or fully off. That simple design method was found to be no longer workable with modern washing machines using higher technology. So Watts put a team of engineers on the project to reengineer the IntelliFlow (tm) products, the result is a truly more intelligent, high-tech IntelliFlow. In fact, new IntelliFlow devices actually "learn" the unique electrical characteristics of each brand and model of washing machine during a learning period. Once IntelliFlow learns the pattern of the electrical current of the washing machine, IntelliFlow then creates a program to monitor the electrical current within the learned parameters.

The modernization of IntelliFlow (tm) required extensive reinvention of the electronics of the Watts IntelliFlow (tm). The design work, engineering, fabrication of prototypes and testing has all been done and a successful product is currently available.

A2CWBM1 Features / Specifications & Link to Installation & Operation Manual

Stop a Flood with IntelliFlow - It's All Automatic!

The Watts IntelliFlow(tm) Automatic Washing Machine Shutoff Valve uses a state-of-the-art electronic control device that senses the washing machine current flow. When the washing machine is turned on, the controls detect the current flow to the washer, opening both hot and cold water inlet valves to allow water to flow to the washing machine. When the washing machine completes the full cycle the device senses the lack of current and closes the water inlet valves. These valves remain closed until the machine is used again. The IntelliFlow's(tm) automatic operation and floor mounted leak sensor protect against catastrophic water damage should a washing machine inlet hose burst while the machine is in use.
