Description
The GeoFlow PG-25-LM is a lower-mount pressure gauge built for monitoring supply and zone pressure in drip dispersal and other onsite wastewater systems. Its 1/4″ NPT lower connection threads directly into control panel manifolds, pump discharge lines, or filtration assemblies, giving installers an at-a-glance pressure reading to confirm proper system operation and catch clogged filters, pump issues, or line restrictions before they cause a service call.
