But you say in another post that from other testing it

anyway, so fiddling with the cycling time of this
box, assuming that's possible doesn't sound likely
to yield much in the way of improvement

I would wholly agree with that sentiment.

It takes about a half hour just to get about 3 minutes to 5 minutes of well
water.

Then it goes dry.

In fact, it might be helpful for me to change the setting to one hour, so
as to cycle the pump less frequently.

I may devise a test to test that out.
