ShurFlo 5.7

[david brady]

Sadly, I'm on my second one too. The later pumps, after 9/2006

have a pressure adjustment screw. There's a cover on the

end of the pump, the cover will have 5 screws. The center

screw is either philips or torx. That screw adjusts the internal

pressure sensor. If your cover only has 4 screws, then you have

an old pump, and it's not adjustable. My first pump exhibited

the symptoms Ryan describes, I was able to adjust the pressure

to cure the problem, but the pump didn't last long after that. My

second pump has given good service so far (slightly over year so

far, yippee).
