Watts 6644 – Frequently Asked Questions
1) Does the Watts 6644 washing machine valve shut off both hot and cold with one handle?
The Watts 0006644 Duo-Cloz is a single-lever valve that controls both the hot and cold supply together. One lever handle closes both sides, so a property manager or tenant can kill both supplies to the washer in one motion instead of reaching behind the machine for two separate stops. Hot and cold inlets and outlets are all 1/2 inch.
2) How does the Watts 6644 connect to my existing 1/2 inch copper stub-outs?
All four ports on the 6644 (hot and cold inlet, hot and cold outlet) are 1/2 inch male threaded, and the valve ships with copper ell adapters that can be either soldered or used with compression. That means you can sweat it onto 1/2 inch copper rough-in or make up a compression joint without changing the rough plumbing.
3) Is this washing machine valve rated for the hot water temperatures in a commercial laundry room?
The 6644 is rated to 180 degrees F and 150 PSI. That covers typical domestic and multi-family hot water supply, which is normally delivered well under 140 degrees F, and leaves headroom on pressure for buildings running at the high end of normal street pressure.
4) Is the Watts 6644 an automatic or a manual washing machine shutoff?
Manual. The 6644 is operated by its lever handle, so there is no leak sensor, solenoid, or power connection involved. If you need the supply to close by itself on a leak event or when the machine is idle, this is the wrong product type and you want an automatic or electronic washing machine shutoff instead.
5) What do I need to connect the washer hoses to this valve?
The 6644's outlets are 1/2 inch male threaded, which is not the 3/4 inch hose thread a standard washing machine fill hose uses, so plan on the hose adapters or hose-thread bibb nipples that suit your installation. The copper ells supplied with the valve are for the supply side, soldered or compression, not the appliance side.
6) Is the Watts Duo-Cloz valve body brass or plastic?
Brass body. For a valve that sits inside a recessed laundry box and may go years between operations, the brass construction is what lets it take repeated open and close cycles and hold against 150 PSI line pressure.
7) What is the exact part number to order the Watts 1/2 inch Duo-Cloz valve?
Order it as Watts 0006644, model 6644. It is the 1/2 inch brass Duo-Cloz manual washing machine shutoff with copper ell adapters, and there is a single configuration, so there is no finish, handing, or size option to specify.
