Pumps, Wells, Tanks, Controls / Re: About to drill well - Need Advice

I really do like the "modern" capabilities of the Grundfos SQE but like you mentioned, it doesn't have the GPM capacity and the control unit is sketchy (Although Grundfos claims they ironed out the issues with the electronic controller).

How many GPM's do I need for 2 single family homes?

One driller recommends Franklin pumps and the Franklin Controller. He said it was the SubDrive Constant Pressure System and he claims the Franklin control boards are bullet-proof when compared to the Grundfos systems.

Pumps, Wells, Tanks, Controls / About to drill well - Need Advice

« on: June 29, 2016, 11:42:47 PM »

About to drill a well in Northern AZ. The well depth will be around 350-400 feet deep with around 30GPM.

I have been given 2 options for the well pump:

Grundfos 1.5 HP 10GPM (10SQE 15-330) and the CU301 Controller - $3,800 installed
Goulds VFD 2.0 HP 13GPM (13GS20) and the AquaDrive Controller - $4,700 installed

The well drilling costs are around $6,800 (400' deep, casing, etc)

The house has not been built so the well is being put in to provide water for the job site, compaction, etc.
