ensure the pump is shut o and depressurized. Remove the tank lid.

Suggestion for removal of the inlet valve assembly
After removing the inlet lter (1) insert an 8 mm (5/16”) hex wrench
into the hex opening (2) and unscrew the inlet valve tting (2) from the
sprayer.
Snap the lid back onto the sprayer, turn it upside down, and tap the
bottom of the sprayer a few times to loosen the inlet seat (3), ball (4),
and spring (5).
With the sprayer still upside down carefully remove the lid. Be careful
not to lose any of the removed parts unless you plan to replace them
instead of clean them.
Flip the sprayer right-side up again and remove the O-ring (6) with an
O-ring pick or tweezers.
Inspect and clean the inlet valve housing area where the inlet valve assembly was
removed with the appropriate cleaning solution.
2. Lubricate the O-ring (7) with penetrating oil (WD40) and install onto the inlet tting
(8). Lubricate the O-ring (7) once more after it is installed on the inlet tting.
3. Replace all parts back into the inlet valve housing in the reverse order of how they
were removed.
Note the correct orientation of the inlet valve seat (3). The taper should be
facing downward upon reinstallation.
Replace inlet valve tting (2) by screwing it into the sprayer. Tighten securely with a
8mm (5/16”) hex wrench. Torque to 50-57 in. lbs (5.5 - 6.5 N.m). Do not overtighten
the inlet valve tting.
Replace inlet lter (1).
