Weird well pressure issue after power outage

So at 2:18am yesterday morning we lost power, it didn’t come back until roughly 9pm. We are on a private well, Grundfos pump roughly 4 years old. I can see the pressure gauge on the pressure tank build up and stop when it’s supposed to at roughly 68#. It also kicks on when its supposed to at roughly 38#.

Between the tank and the heater is a 50 micron spin down, and 2 10” filters with 20 and 5micron filters respectively. Then the flow hits the heater.. so the issue is once power came back we’ve had no pressure post softener. I say that kinda loosely.. post softener. Because Ive put the softener valves into bypass and there’s still no pressure. A trickle.. not even enough pressure to fill a toilet tank.

I’ve had the valves off to check for blockages and there aren’t any. And I can open the spin down drain and water shoots out like it’s supposed to. Now, being that the softener is about 4 years old, the heaters like 3 months old. Is it possible, depending on water quality, that a chunk of something broke off and is plugging up a pipe?

There is no other logical explanation.. no valves half open, no other faucet or water outlet is open. There can’t be a leak in the drop pipe or else the pressure tank would get nothing.. Looking for thoughts Freon the brain trust since I’m on hour 30 roughly with no shower and its been a good 23 hours now since I slept. Beyond pissed and frustrated at this point.

Before this issue gets forgotten by me Im hoping there's some well smart folks around here.

Realizing that water wells could be like fingerprints.. super unique. Every time we lose power for more than say 8 hours, once regained the well pump seems to **** up a bunch of sh1t that's outside the norm. I wonder why?

Like.. could the water table rise due to un-use and therefore bring sediment up with it?

Sounds like it's loosing prime?

It better not be.. Damn pump, and drop pipe are under 5 years old. I'll have to pay attention to the pressure when we lose it next time... with Consumers Energy that's the most reliable thing about them.

I have seen this happen before when power was lost. I have no idea what caused it.

In this case, the filter was before the pressure tank so the pump just continued to run and below the fuse.

I have questioning whether or not to filter pre pressure tank. I mean.. all that funk is getting into the bladder. Surely it's not good for it, but then just like you mention if the pressure switch is never tripped or takes forever then you risk pump damage.

I'm on rain water that's "pre-filtered" by some rough screens and "first-flush" system, but sometimes it gets junk in there.

But before I go into the pump (or the pressure tank / Stop Cycle System) I run it through a "spin-down" sediment filter with a 30 mesh screen on it. It catches the "big" stuff and you can just "dump" it without much drama... Actual 20" sediment filters are after the pump.
