My foreman in Tampa insisted we run the suction line at a 22-degree angle for silty bottom, and after a year of fighting it, the pump clog rate dropped by half.
He said the steeper pull kept the fines moving better than the flat 15 degrees I was taught, and honestly, I thought he was full of it until we tried it on a stubborn channel job last spring. Anyone else have a specific angle that works best for different bottom types?

Wait, 25 degrees for clay like @shaneb16 said? That's wild, I've only ever heard you need a flatter pull for that stuff. Makes me question everything they taught us in school, honestly.
