Switched from a 4-inch to a 6-inch suction line on the old cutterhead dredge last season
Honestly, the difference in our yardage numbers was huge. Over a three month job on the Lake Erie channel, we went from moving about 150 cubic yards an hour to pushing 220. The bigger hose just let the slurry flow so much easier, cutting down on clogs and pump strain. Tbh, I should have tried it years ago. Anyone else seen a big jump from just upsizing the suction line?

That reminds me of when we switched our discharge hose size.

Wait, you actually changed the hose size? @lilyp37, that's a huge deal. I saw a crew try that once and the whole pump cavitated because the flow was all wrong. They ended up with a massive pressure drop and had to shut down for hours. Switching diameters isn't just a simple swap, it changes everything.

Yeah the part about the pump cavitating is SO real. It's not just a pressure drop, the whole system can get wrecked. I've seen that happen too and it's a total nightmare to fix. People don't get how much math is behind just a simple hose size. It changes the flow speed and everything.
