A rock in the pipeline showed me not to skip line checks.
My dredge lost suction during a silt dig. I blamed the pump, but my partner insisted on checking the pipeline, where we found a rock jam. Do you usually suspect pump issues or line blockages first?

Heard from a buddy in construction that line jams cause most suction problems. Pumps get blamed because they're right there, but the blockage is usually hiding in the pipe. Starting with a line check just makes sense to avoid wasted time.

Always check the line first.
We made that mistake last year on a river job, assuming the pump was shot after a sudden pressure drop. Wasted half a day tearing it apart before someone finally walked the line. Found a solid clay plug about sixty feet in. The pump is the easy thing to blame because you can see it right there, but the pipeline hides all the surprises. A quick visual check along the length for dips or a pressure gauge reading at the pump can save you a huge headache.

That's a solid lesson learned the hard way. My crew got burned by a similar thing on a pond cleanout. The pump seemed fine but the flow just died. We started with a line check and found a section of old, buried hose had collapsed on itself. It's way faster to walk the line and look for kinks or low spots before you crack open the pump.
