What to do if Clarke Pressure Washer has low pressure on initial use?
- FFrancis Orozco DVMAug 2, 2025
If your Clarke Pressure Washer has no or low pressure during initial use, check that your water supply can deliver 5 gallons per minute at 20psi. Ensure there are no leaks in the high-pressure hose fitting—tighten it and use sealant tape if needed. Clear any obstructions from the nozzle and clean the water filter screen. Also, make sure there is no air in the hose: turn off the engine and water supply, disconnect the water source, turn on the water to expel air, then reconnect and turn the water back on. Finally, pull the trigger to expel any air in the gun/wand.
