The new GPH GPST emitters are designed to perform in the harshest environments, bringing commercial grade ruggedness to drip irrigation while providing an unmatched CV ratio.

This means they are turn key and maintenance free, no more call backs due to inconsistent flows from one emitter to another.  Our patent pending screen keeps debris from contaminating the emitter by increasing the size of the inlet by 250%.  The GPH screen was engineered with an o-ring molded into the face to ensure a leak free installation without the use of Teflon Tape.

Check Valve:

The Spec-Check utilizes spring check valve technology to create a true check valve with a 10 PSI cracking pressure.This saves water by eliminating low head drainage for up to a 15 foot elevation change. The combination of the Spec-Check along with GPH’s GPST & GPCB ensures that your system will operate at the highest level of performance and efficiency.
