Netafim Pressure Gauge Needle with 1/4" FPT

Follow these steps to safely check your system's water pressure.

Step 1: Depressurize the Line
Always ensure your irrigation system is completely turned off and depressurized before attempting to install or remove any testing equipment.

Step 2: Attach the Gauge
Thread your 1/4" MPT pressure gauge directly into the 1/4" FPT port on the Netafim needle adaptor. Tighten until snug using basic hand tools, being careful not to overtighten.

Step 3: Insert the Needle
Insert the needle end into the designated pressure test port (or Schrader valve) on your filter housing, inline valve, or dripline connection.

Step 4: Read and Remove
Turn the water source back on to pressurize the line and take your gauge reading. Once finished, turn the water off, allow the line to depressurize, and carefully remove the needle.

How do I use the Netafim Pressure Gauge Needle to check my system during spring startup?
Insert the needle with an attached gauge into your system's test port when turning on the water in spring. This verifies your pressure regulator is working and lines aren't over-pressurized after winter dormancy.

Verifying your system's pressure at the start of the season is critical. A failed regulator can blow out drip emitters, while low pressure indicates a clog or a leak somewhere in the mainline.

What size pressure gauge fits the Netafim Pressure Gauge Needle?
The Netafim Pressure Gauge Needle features a standard 1/4-inch Female Pipe Thread (FPT). It perfectly fits any pressure gauge equipped with a 1/4-inch Male Pipe Thread (MPT) connection.

If your gauge has a different thread size, you will need a separate threaded adapter to connect it to this needle securely.

Can I leave the Netafim 1/4" FPT Needle installed permanently?
No, the Netafim 1/4" FPT Pressure Gauge Needle is designed as a temporary diagnostic tool. You should remove it after recording your pressure readings and store it safely to prevent damage.

Leaving diagnostic needles in test ports permanently exposes them to environmental wear, accidental bumps, and constant pressure fluctuations that could lead to leaks.

Do I need to turn off the water before using this Netafim pressure testing needle?
Yes, you must always depressurize the irrigation line before installing or removing the Netafim pressure gauge needle to prevent water spray, equipment damage, or inaccurate gauge readings.

Once the needle is securely in place, you can slowly turn the water source back on to pressurize the zone and record your measurement.
