Why Black & Decker Water Pump does not reach working pressure?
- JJames KnappAug 16, 2025
If your Black & Decker Water Pump isn't reaching working pressure, several factors could be at play. First, ensure the water supply tap is fully open to maximize water supply pressure. Check the tightness of hose fittings to prevent air from being sucked into the system. If there's air in the pump, switch off the appliance and repeatedly depress and release the gun trigger until a steady water flow is achieved, then switch the appliance back on. Also, verify that the adjustable nozzle is correctly positioned. If none of this helps, the nozzle may be worn and needs replacement, or the water filter could be fouled and requires cleaning. Lastly, the thermostatic valve may have tripped; in that case, wait for the correct water temperature to be restored.
