Check valve – 1 ½”
This compact check valve has been specifically designed to provide a second level of security for installation with a Hartford loop.
Opens only to allow air to be blown through the jets when the blower is in operation, and closes as soon as the blower is off preventing water from reaching the blower.
The check valve must always be installed vertically with the air flow going down through the device. This prevents a water column to build up on top of the check valve.
- Only 3 5/8 “x 2 1/4” for an easy installation in tight spaces.
- Individually tested to UL and CSA standards at 35psi and up to 70˚C.
- Ultra-light spring to prevent vibrations.
