When using overhead (inverted) irrigation in greenhouses, each sprinkler or mister assembly should have an anti-drip device installed to prevent dripping from the sprinklers or misters after the system shuts off. Prolonged dripping can cause damage to the plants directly below, especially to seedlings.
To install a press-fit sprinkler or mister and anti-drip device into poly tubing:
- Use a punch to make a 1/4" hole in the poly tubing.
- Assemble the press-fit components before inserting into tubing.
- To Assemble: Connect the threaded end of the anti-drip device (MEAD) to the press-fit mister or sprinkler (Tornado Mister, Ein Dor, or Wing Sprinkler). Then connect the press-fit side of the anti-drip device to the press-fit barb ().
- Insert the barbed end of the press-fit barb into the hole punched in the poly tubing.
To install a press-fit sprinkler or mister and anti-drip device into PVC pipe:
- Drill a 7/16" hole into 3/4" or larger PVC pipe, use a bit that will not shatter PVC ().
- Insert the grommet () into the hole.
- Assemble the press-fit components before inserting into PVC pipe.
- To Assemble: Use the press-fit coupler () to connect the anti-drip device (MEAD) to the press-fit mister or sprinkler (Tornado Mister, Ein Dor, or Wing Sprinkler).
- Thread the anti-drip device into the grommet.

I grow teaching gardens, I've designed 6 large gardens and each one has been designed with a drip or low pressure irrigation system. I also have a propagation greenhouse. I've been able to find all the fixtures for my systems at DripWorks. Shipping costs are reasonable and the service is fast.
