A hose nozzle may lose pressure when grit or mineral fragments lodge in its inlet screen or spray openings. Flushing is simple when the nozzle is disconnected and the blockage is not forced deeper.
Shut off the water
Close the spigot, release pressure, and disconnect the nozzle. Inspect the washer and inlet screen before turning water back on.
Rinse the inlet
Hold the nozzle so debris can fall out, then rinse from the outlet toward the inlet if the design allows. Use a soft brush for deposits and never force a sharp wire through a small opening.
Check the hose end
Flush the hose briefly without the nozzle attached. Replace a damaged washer and straighten kinks that can mimic a clogged nozzle.
Test gently
Reconnect the nozzle, open the spigot slowly, and check for leaks around the coupling.
