Looking for advice with well problems...

They also have some crushed sand that's 1/4" and below, but my worry is that, since these little grey 1/16" rocks are making it through, I didn't want to put something down there that's just going to be sucked up.

Crushed stones having sharp irregular edges "lock" together to form a filter.

Which chart... the graph, or the table? If using the graph, and you will use a 40/60 switch, add 14o ft (60 psi converted to ft of water) to the actual depths to make sure the pump will turn off when water level falls as far as the pump. It is ok for the gpm to be reduced at that point.

If using the table, it is easier.

Was going off of the graph, one if the "pictures" with the product photo.

As an update, I cut the 157ft of poly tubing back to 135ft and reinstalled the pump. The rattling sound in the pipe between the well cap and pressure tank lasted for about a minute and then it was gone. Totally silent running now, and of course the pump still works, so that's cool. I watered the garden and will try the sprinklers this evening.

Not gonna slack though, time to start rounding up parts. Will also have the well bailed before installing nice new parts.

100 PSI poly is meant for sprinkler systems. Wells generally use 160 or 200 PSI poly.

Roger that, thank you. Was looking at the Home Depot stuff, but I see the proper tubing from aquascience is 200psi, will definitely use that.

Okay, 3/4hp it is. I've been emailing the aquascience folks trying to figure out why the 10Sq07-200 is more expensive than the 10SQ07-240, because it seems like the pump that can produce 10gpm at 200ft of dynamic head should cost less than the one that can do 10gpm at 240ft of dynamic head.

At 1 gpm, 10SQ07-200 has about 290 ft of head. That translates to 125.27 psi. 160 psi pipe would be enough.
At 1 gpm, 10SQ07-240 has about 395 ft of head. That translates to 171.2 psi. 160 pipe would not be enough.

I don't know why there is a premium for 10SQ07-200. I think that is the one I would use if I had a pump failure.
