Wear on the ball is almost impossible to detect
visually. To test for a worn outlet valve assembly,
turn the pressure control knob clockwise to its
highest setting and run water only through the
pump for 10 to 15 minutes without triggering the
gun.
If the valve is defective, the end cap will get very hot
to the touch. If it is functioning properly, it will stay
approximately the same temperature as the water
running through it.
8.2 Removing and Cleaning the Outlet Valve
It may be necessary to remove and clean the outlet valve or to
replace parts inside the valve worn out through normal use.

This spring is manufactured to a very specic
tension. Do not stretch the spring. Do not put in
an unauthorized substitute. See the paint pump
assembly parts diagram for the proper replacement
part number.

wear or damage, replace them with new parts. This carbide
ball must seal tightly against its seat for the valve to function
properly.
