Noise Reduction Valve: QPL-20
INSTALLATION INSTRUCTIONS:
- STEP 1: Turn off the washing machine tap and unscrew the hose if connected.
- STEP 2: Screw the Quiet Valve onto the end of the tap where you removed the hose using the sealing washer provided. NOTE : No thread seal tape is required.
- STEP 3: Re-fit the washing machine hose to the Quiet Valve and ensure that the strainer and seal are centrally aligned inside the attaching washing machine nut to prevent any obstruction to the flow.
OPERATION:
The Quiet Valve is designed to reduce the noise caused by high velocity water and water hammer. This is achieved by reducing the outlet pressure through the Quiet Valve to an acceptable level. The use of the Quiet Valve also reduces the risk of burst hoses.
