If experiencing cavitation, pressure fluctuation, or poor flow, check the inlet strainer first.

Frequently Asked Questions

It’s primarily specified for GH 130 / GH 200 / GH 300 (and often GH 230). If you own another series (Ultra, Ultra Max II, GMAX, Mark, etc.), check your parts manual for the exact inlet strainer part number to avoid mismatch.

Mesh indicates screen opening size. A 10-mesh screen has 10 openings per linear inch—ideal for intercepting larger debris before it reaches the pump.

Inspect after each job. Clean with compatible solvent and a soft brush. Replace if clogged, damaged, or if performance issues persist after cleaning.

Inconsistent pressure, pulsation, cavitation noise, reduced flow, or frequent tip clogs are common signs. Inspect the inlet strainer first when troubleshooting.

Power off and relieve pressure. Remove the suction tube per manual, seat the strainer fully and squarely, then reassemble. Prime with clean material and check for leaks or flow issues.
