Installation Requirements

The Watts 3/4" LF008PC-QT is designed for indoor point-of-use applications, specifically for connecting to the potable water supply. It features Female NPT Ball Valve Shutoffs for secure connections.

  • For factory-installed applications on machines or equipment, the critical level of the backflow preventer should be installed not less than 1 inch (25mm) above the flood rim.
  • For general plumbing applications, the critical level of the backflow preventer should be a minimum of 6 inches (150mm) above the flood rim.
  • A strainer is recommended to be installed ahead of the backflow preventer to prevent fouling of the check assembly and potential spillage.

It is important to avoid installing this device in concealed locations or areas where water leakage due to normal wear of internal parts could cause damage.
