Click here for Product Info and Installation Instructions Series SD3 is a dual check with atmospheric port designed for the protection of the water supply from carbon dioxide gas and carbonated water. These substances can flow from post-mix beverage systems and are very acidic. If the acidic water comes in contact with copper tubing or copper pipe, it will cause the leaching of copper salts into the water supply. The dissolved copper if ingested can cause nausea, abdominal pain, and in some cases vomiting.
The SD3 prevents the reverse flow of potentially contaminated water into the potable water supply. The SD3 atmospheric vent provides a visual indication of failure in the event that the downstream check fails and system back-pressure exceeds the supply pressure.
Watts SD3 is recommended for use on Post-Mix Carbonated Beverage Equipment and equipment for tea and coffee.
Before installing, flush out pipe lines to remove
scale and other foreign matter. The valve can be
installed horizontally or vertically (flow up or down).
Install the valve in the line with the arrow on the
valve body pointing in the direction of flow.
Connect a vent discharge line to the vent outlet of
the SD3 and vent to a safe place of disposal with
adequate ventilation. The valve should be installed
such that the strainer and the valve are accessible
for service and maintenance.
