Talked with an old timer at the dock in Astoria who said he never uses his cutter head in silt. I thought he was crazy, but he showed me his pump wear logs.

My pump logs tell a similar sad story.

Man, makes you wonder what the logs from the riverbed itself would show, right? Like how much junk is even down there.

Ugh, tell me about it... Jennifer833 is totally right about that silt. I had a pump last year that sounded fine but the logs showed it was working way too hard. Sure enough, it was full of grit when we opened it up. Those logs don't lie.

Hate to see that, but you have to listen to the guys who've been doing it for forty years. They've learned the hard way so we don't have to. Stone.lisa has the right idea paying attention to those logs. It's the only way to really know what's costing you money. That silt is like liquid sandpaper, just eats a pump from the inside out.
