  • Replacement riser pin for the NMG-49
  • Prevents geysers if the sprinkler head breaks off
  • Fully adjustable and installs directly into your existing sprinkler system

Essential Info

The No More Geyser NMG-43 is a replacement riser pin for the NMG-49 system. Install the NMG-43 directly into the water supply line, with a retaining pin held in place by the sprinkler head. When the sprinkler head moves, the retaining pin moves out of the way, and the water pressure causes the ball to seat in the valve fitting - stopping the flow of water through the riser.

More Info

Easy to Install
  • Simple retrofit - no big holes to dig, just remove existing sprinkler head and riser and screw in the NMG valve and riser, then re-install your sprinkler head and turn the system back on
  • The NMG fits directly below the sprinkler head and is as easy to install as changing a light bulb

    Fully Adjustable
  • The length of each NMG is fully adjustable to accommodate the depth of any existing sprinkler system
  • The riser and retaining pin are marked with corresponding cut-marks, making any depth adjustment easy to accomplish

    Verified Water Conservation Results
    Independent third-party testing found that
  • NMG saves 9.5 gallons per minute, or 95 gallons for every ten-minute watering cycle
  • The presence of the NMG units in the system causes a minor 0.1% increase in pressure loss
