At least that indicates that the very expensive items are working OK. If you hook up a hose to that faucet on the tank, turn fully on and time the length of time it takes the pump to run for a re-pressurizing cycle (from pump turn-off to turn-on) that would help narrow down the possible causes of the problem.
Since your filter is in the system BEFORE the tank, it will only be the problem if the pump runs for an excessive amount of time in order to reach its cut-off pressure.
Is the water pressure low ALL THE TIME in the house or is it normal at first and then diminishing and takning a very long time to build up again?
I sure hope you are right in your first sentence.
The pressure is fine for the first few seconds or so, then it drops off. It didn't occur to me that I should let the "raw" faucet run for a bit to see if it dropped in pressure too.
So I should connect a hose and note the length of time the pump is *off* between the times it kicks in? What would be a good or bad indicator?
I'll try the hose when the sun comes up.
I just heard from my husband and I asked him about it.
He said he changed the filter before he left Sunday. He said he put in a high quality, refined (sand?) filter and maybe it's somehow restricting the flow. He said maybe try a regular, paper filter and see if that helps.
What do you think? He's new to wells also so he could be way off.
