A precipitous drop in the house water pressure sent me to check the pressure on the bladder tank - only 20 psi on system with a pressure switch set for 30-50 psi.   I clamped an ammeter on one of the pump wires at the breaker and its running continuously @ 7A, like it should since it hasn't reached cut-out at 50 psid, but it's not producing any pressure greater than 20psi with no load on the system.

I turned the 240V pump breaker off and the water pressure dropped to zero over 3-5 minutes, so the water's draining back through the pump.

Clearly the 30+ year old submersible well pump is on its last legs.

My question:  Any opinions about US residential submersible pumps?  Brands to use or brands not to use?
Given the costs of replacing, I'm not looking for cheap.  I'm looking for quality that'll last and I'm willing to pay a premium for a better product.
