if you send water directly up the water pipe going into the powerhead does it look like the flow is restricted
or… try pushing som air pressure up the water pipe can you sense that the air is not free flowing and pressure is building up
if you take the powerr head off can you try sending air pressure backwards in case some passages got plug up with impeller rubber chips
etc….
