Just had a new pump installed at CW a month ago. I now have very little output from the galley sink, a noticeable surge flow from shower and bathroom sink and a solid, good flow from the toilet and wand. Without the good flow part, I would think the pump is the issue. Where should I start to look to resolve this?
Thank you

SURGING
The newer model 5.7 pumps have a pressure adjustment screw in the middle of the pump cover. Try tweaking it to stop the surging. ShurFlo rep told me this and it weorked on one of my MANY pump problems.

LOW FLOW AT KITCHEN SINK
Remove the spray head and check the flow from just the hose. Spray head could be plugged.

I've removed the spray head and it was part of the problem. With it removed (spray head), I get a decent flow of water. However the surge in the flow remains. It surges at all outflows in the coach.
I have searched for the pressure adjustment screw and cannot find it. I have a brand new (from Shurflo) backup pump and cannot find it on it either. Anyone who can direct me to it will win the grand prize. A picture will win a double grand prize.
Thanks to all

On the end of the pump, opposite the motor, is a retaining cap with 4 screws holding it on. In the middle of that cap is the pressure adjusting screw. Be careful to not overdo it. Give it 1/4 turn at a time and try it until it stops surging. Count the number of turns so that you can go back to where it was if you go too far or in the wrong direction.
