Check Valve Service
The one–way check valve that is positioned between
the flush (water) tank and the ball valve (see schematic)
prevents paint from entering the flush (water) tank when
the paint/flush lever is moved from the paint position to
the flush position and while the machine is operated in
the flush mode.

NOTE: If the flush system is not cleaned after use, di-
luted paint may cause check valve and associated
hoses to become blocked. If the check valve is stuck
open, paint may enter the flush (water) tank when the
paint/flush lever is moved from the paint position to the
flush position. If the check valve is stuck closed, the flush
system may not operate.
