Hello all!
I was hoping to get some recommendations/insight on what is my best path forward on a pump control setup for my new residential home construction.
A little backstory:
We had a well drilled on our lot back in February and had to get a flow test for bank loan requirements. We ended up going with the same well pump installer that all the other neighbors went with since they all were happy enough with the results. The installer went ahead and installed a Grundfos 16S30-24, 3 phase, 230V, 3 HP centrifugal pump. At the time I had little understanding of well systems and didn't have the time to get up to speed since we needed to get the loan rolling.
Fast forward to today and we are getting ready to install the pump control system and associated items (VFD, pressure tank, etc.). The installer wants to go with a Pentek Intellidrive PID-30 VFD controller and an 81 gallon pressure tank. However, since the pump install I've had some time to do enough research to notice that many folks are suggesting that VDF systems are perhaps not the ideal solution, but rather it is more effective to go with a more traditional setup with a Cycle Stop Valve to get the benefits of a constant pressure system. But it also sounds like I may be stuck with a VFD setup unless I pull the current 3 phase pump and swap with it for a single phase one?
I feel that I have done enough research to be dangerous, so my question is, should I simply move forward with the VFD setup and re-address this when it eventually fails, or does it make more sense to pursue a different route?
If it helps, below are my well specs that I have on hand:
Well diameter: 6 inches
Drop pipe: 1 1/2 SCH 120 PVC w/ S.S. Couplers
Depth: 540 feet
Standing Water Height: 175 feet
Pump Setting: 428 feet
volume test (required by bank) showed 23 GPM over a 2 hour flow period.
Cheers!
