15 Count Bulk Package. Each Newly Designed Adjustable Dripper is adjustable by turning the Top Dial to water from 0 to 10 GPH and releasing drops of water from a drip to a small 8-stream spray pattern. The Newly Designed Top Dial has a built-in positive "Stop" feature that prevents a cap from blowing off easily if the top is rotated too far to the left.
When increasing the water output, you can open the Top until you feel a positive "Stop" resistance to know that it is fully open. The Tops can be removed if needed. To do so, once the Top is in the fully open position, simply twist the Top with more force in a "counter-clockwise" motion to remove it. To reassemble, use force pushing the Top back on while also turning it in "clockwise" motion until you feel it catch the threads. In the event of a lost cap, or if you need a Replacement Cap/Top, these Replacement Caps (MLD-STACAP) can be purchased separately. Replacement Caps ONLY work on the newly designed Adjustable Drippers.
Use these Adjustable Drippers to gently water patio and potted plants, or landscapes. Install these Drippers directly into the 1/2-in Poly Tubing by first snapping a hole using either of our Hole Punch Tools (MLA-51, MLA-TOOL).
If you punch a hole in the wrong place or want to relocate the Dripper, then simply remove it from the 1/2-in Poly Tubing and snap in one of our Goof Plugs (MLA-51G)
These Drippers can also be installed by running a piece of 1/4-in Vinyl Tubing to the plant from the 1/2-in Poly Tubing using the enclosed 1/4-in Barbed Couplers, then by pushing in the Dripper at the other end of the 1/4-in Vinyl Tubing next to the plant.
After the last Dripper is installed, turn on the water and allow the flow of water to clean out any debris that may have entered the line during installation.
Our 1/4-in Support Stakes (MLT-DST) can be used to securely hold the 1/4-in Vinyl Tubing and 1 GPH Dripper near the plant
Also use our 1/4-in Tees (MLT-TEE) and Elbows (MLT-ATE) to run the 1/4-in Vinyl Tubing in opposing directions or in tight corners to supply water to these Drippers.
(15 Adjustable Drippers per bag)
(Made in the USA)
Drippers and Drip Tubing should NEVER be buried underground but can be covered lightly with Mulch.
RECOMMENDATIONS & LIMITATIONS
When installing any irrigation system, it is important to be aware of manufacturer recommendations and potential system limitations. Please be aware of the following: Order of Installation is critical for proper system function. This is the order in which parts should be installed, starting from an outdoor faucet.
1) Check your outdoor faucet to make sure there is an attached or built-in Brass Anti-Siphon Vacuum Breaker that is designed to prevent the backflow of fluids into the potable/drinking water system.
2) A Metal "Y" Fitting is suggested so you can attach your garden hose.
3) The Electronic Timer (MLWT-1ZONE, MLWT-TWOZONE), or our Mechanical Timer (MLWT-EGG).
4) Pressure Regulator. When using Drippers, we highly suggest using our 25 PSI Pressure Regulator (MLD-25PR).
5) 150 Mesh Filter (MLFF-41), is suggested when using Drippers or when using our products with "well" water.
6) 1/2-in Poly Faucet Fitting (MLF-33) to connect the 1/2-in Poly Tubing, or the 1/4-in Faucet Adapter (MLA-FAS) to connect the 1/4-in Vinyl Tubing.
