Hotsy Pump Check Valves | Hotsy Pressure Washer Pump Repair
We recommend replacing Hotsy pump check valves at the same time as replacing
Hotsy Water Seals. The springs of the check valves can become worn or broken, resulting in failure of the check valve, causing loss of pressure and a chattering noise or shuttering of the pump head. Broken pieces of valves and springs can flow through the pump, causing damage and failure of other pressure washer components, including the unloader valve (pressure regulator), connecting hoses and pressure gauges.
