  I was given a Troy Bilt a couple of weeks ago because it "wouldn't
build pressure" and I think I figured out why . There is a ball check
vent valve on the HP outlet . The spring holds the ball off the seat
under normal hose pressure but as soon as the pump builds pressure the
ball is supposed to seal the outlet . Except the ball and spring are
missing ... Soooooo , the question is , if I can't find the ball and
spring can I just plug the hole ? I think the only difference it will
make is that I'll have to hold the wand trigger down while starting the
unit . I just replaced the bypass valve because it had a crack on the
piston head . I think the missing ball and spring are venting enough
pressure that the bypass valve never opens . I'd like to get this unit
running , it has higher pressure and flow rate than the last one I got
for free .

A bit confused here; does the missing ball check valve vent to air?

FWIW there's a Youtube channel called "Mustie1" with at least a few
pressure washer salvage videos, along with many more.
