Hi, Larry,

Al (poconos) will be along soon...he's the one who, I think, initiated the DE idea.

That normal psi of 26 seems okay but somewhat on the higher end of average. I wonder if that big pump is forcing the water through your filter too fast? Might be causing some channeling or maybe just forcing the silt thru the laterals.

The DE is the easy fix. If that doesn't work, I'd take the top off my filter and see what it looks like in there. If you decide you're pushing the water too fast into your filter, you could restrict your suction lines at the ball valves and your pressure (and flow) will drop immediately. I know that may go against normal thinking but it actually hurts nothing and reduces your electric bill a little since the pump is constant speed. Again, the DE would solve it most easily.....just watch your pressure.
