Is my VPM functioning correctly?

Over time, the rubber sealing on the VPM can degrade and cause pressure leaks within the system. Perform these checks to confirm that the component parts are working correctly when assembled into a system:

Nozzle O-Ring Seal

Check that the O-ring is still flexible and that the sealing surface has no damage (e.g. pits, flat spots or cuts).  The nozzle O-ring should normally be dry and NOT have any grease applied.

 

If the O-Ring needs replacement, request a VPM Nozzle Replacement Kit from Izon. To replace the rubber O-Ring: 

  • Remove the old O-ring by sliding a tool down the side and levering it up. Take care to avoid scratching the plastic component with the tool. 
  • Fit the replacement O-ring into place.
