This is a work in progress and will be for a while.... Gotta start somewhere!
Installed Grundfos 6 SQF-2 submersible pump in 240' well on our powerless, vacant rural lot. When we need water, we start the generator and plug the pump in. There's no control box, nada. From the pitless, a PVC pipe with valve and hose bib. No pressure tank, to cistern, just the bare-bones.
The (newbie) question I have is regarding pressure/flow control... As it is, pressure coming out is way to high and I'm surprised the cheap garden hose hasn't burst yet!
I can partially close the hose-bib valve to the desired pressure/flow, but won't that be damaging to the pump, running full-power against a partially closed valve, building pressure in the drop-pipe??
Or do I need to add the other bits to my system right away i.e. pressure tank, pressure switch? (Hoping not)
The pump can also handle varying voltages (90-240AC / 30-300DC) @ max 8.4A... would that be another option, to get a thingamajig to reduce voltage from generator hence flow/pressure?
Looking for the simplest solution here. I guess I don't understand what the pump does when it meets resistance at output: does it slow down to match output? Does it cycle? Or does it just keep pumping until the pipes burst?!?
Steep learning curve. Please be gentle.
