Cat Water Pump - reduced pressure?

Recommended Posts

2016 Tymco 435 w/ Cat Water Pump   - Pump just went to about 1/2 pressure.  I say pump, but the pressure at the nozzles is 1/2 of normal.

Did the normal filter check and confirmed good gravity flow into the pump.  This model has the addition of a pump on/off switch by the valve bank for use with the auxiliary water wand.   Is this a pump issue or is there a check valve or other choke point to check first?
