Merrill Mfg. PGNL200 Low Lead Pressure Gauge
Product Overview
A failed pressure gauge is more than a minor annoyance; it is a system-wide liability that leads to undetected pump cycling, blown seals, and inconsistent zones. During the peak of the irrigation season, when summer heat puts maximum stress on your systems, waiting for a back-ordered component can lead to parched turf and frustrated clients. With lead times for municipal and residential components fluctuating, securing your supply of reliable monitoring tools now prevents the logistical headache of failed inspections or emergency service calls. Having these gauges on hand ensures you can verify system performance immediately and keep your project deadlines on track while others are stuck waiting for shipments.
Unlike budget-grade gauges that lose calibration after the first freeze or pressure spike, the Merrill Mfg. PGNL200 is built for the rigors of professional field use. The low lead construction ensures your team stays compliant with modern potable water safety standards without sacrificing durability or accuracy. By installing a consistent, high-quality gauge, you reduce the need for repeat maintenance visits and build trust with your clients through precise system tuning. Stocking these professional units gives your crews a technical advantage, allowing them to diagnose issues faster and provide verifiable results on every job site.

Installation Notes
When installing the PGNL200, always apply a high-quality thread sealant or PTFE tape to the 1/4 inch NPT threads to ensure a leak-proof connection. Use a wrench on the brass hex flats rather than twisting the gauge case to avoid internal calibration damage. Proper placement after the pressure tank or main shutoff valve is recommended to provide the most accurate reading of static and dynamic system pressure.
