Shurflo trouble shooting

[asknupp]

I'm using a shurflo 4008. 3/4 mainline straight to the shurflo. I'm getting a lot of slugging and turbulence just before the pump. Is this normal or do I have a leak somewhere? I do not have any gauges on the system yet. Any info is appreciated. Thanks in advance.

If lines are tight everything should be stopped on the pump inlet and outlet lines, no turbulence, so it sounds like there is a leak. You might check if there is air coming out the pump outlet line, that would confirm if there is a leak.

Thanks Dave,
Cut In valves to each main so that I could divert all vacuum to check for the leaks. Let's just say there are many. Got 4 or 5 fixed and the sap ladders started to perform. Have a few more to work on tomorrow. But I think its going to out perform last year's totals.
