SPW Hunter MPGauge on-head pressure gauge kit – P/N 185200, nozzle-compatible adapter for accurate sprinkler pressure readings

SPW Hunter MPGauge P/N 185200 is an on-head pressure gauge and adapter kit that measures operating pressure directly at a spray or MP Rotator nozzle.

Knowing the water pressure at each sprinkler outlet is crucial for tuning irrigation systems for uniform coverage and efficient water use. The SPW Hunter MPGauge assembly includes an adapter that threads into the sprinkler riser and a precision gauge that accepts typical male-threaded nozzles, making it simple to test pressure at the point where it matters most. It’s compatible with a wide range of spray heads and rotators, so you can audit performance across existing zones without major disassembly.

How does the MPGauge help diagnose pressure problems in a zone?

The gauge lets you read the actual operating pressure at the nozzle instead of relying on distant manifold or controller readings. By comparing measured pressure against manufacturer recommendations for MP Rotators or nozzles, you can spot low-pressure conditions, uneven distribution, or flow restrictions.

• Measures pressure at the sprinkler outlet for accurate diagnostics.
• Reveals low-pressure causes like clogged lines or undersized piping.
• Helps confirm correct pressure after installing rotators or nozzles.

Can I use the MPGauge with different nozzle types and brands?

Yes — the MPGauge uses a female-threaded top adapter that accepts standard male-threaded nozzles, so it works with MP Rotators, rotary, multistream, adjustable, and many standard spray nozzles. The bottom thread fastens to the riser stem or spray body for a secure, leak-minimized test point.

• Compatible with Hunter MP Rotators, standard spray nozzles, and many third-party nozzles.
• Quick screw-on connection for fast pressure checks without tools.
• Includes the gauge and MP adapter for immediate use out of the box.

What concrete steps should I follow when using the MPGauge during an audit?

Thread the MPGauge adapter onto the riser stem, attach the nozzle of your choice into the gauge, then run the irrigation zone to get a steady reading. Repeat across multiple heads in the same zone to detect pressure variations and identify problem locations promptly.

• Turn off the zone, screw the adapter onto the riser, then attach the nozzle to the gauge.
• Activate the zone and wait for steady pressure before recording readings.
• Compare readings across heads and to recommended nozzle pressure for adjustments.

Who is this for? The SPW Hunter MPGauge is aimed at irrigation professionals, landscapers, smart gardeners, and water managers who need fast, accurate on-site pressure readings. It’s ideal for anyone conducting system audits, installing MP Rotators, troubleshooting uneven coverage, or optimizing irrigation to conserve water and improve uniformity. The kit is compact and user-friendly, so both field technicians and informed homeowners can use it to make data-driven adjustments that improve system performance.
