Shurflo Revolution 4008 Adjustments
Yahoo Message Number: 143481
Have any of our members made any adjustments to the water pump by turning either of the screws? I think I need to adjust my pump. I have added the ShurFlo hoses for both inflow and outflow to and from the pump. When the faucet is on full I get constant flow. When I turn the faucet to half the pump pulsates and I am trying to eliminate this. On the Companion site, Delta Mike has a diagram of the pump showing two adjustment screws, one in the middle to adjust pressure and one in the lower left for by-pass. I am not sure which one to adjust, other than the documentation from ShurFlo says that only a technician should make the adjustment for the by-pass. I have read from different sources that one says to adjust the middle screw and an other says to adjust the lower left screw. Has anyone done this adjustment? Has it worked?

Thanks for your help Kevin

Middle screw.  Turn clockwise.  I was able to get most of the pulsating out doing this.

Thanks Joe, it worked. I turned the middle screw about 1/2 turn and the pulsating stopped and the pump turned off within 1/4 second after the faucet was turned off, as it should. Thanks for your help.
