Whole house water pressure is low

We added bleach to well head,then let bleach sit in the well to disinfect any bacteria. Then ran all faucets to bring the bleach through the lines to disinfect. We did that for several minutes, then turned all off for the night. Ten hours later, the water pressure in the whole house is very low. The water will still run at various faucets (one at a time), but low stream.

First remove the faucet aerators and flow restrictors to make sure they are not clogged.

Do you have any water filtration? If so check to insure that the filter cartridge does not need changing or the filter back washed or flushed.

Do you have a pressure gauge on your system? What pressures does it show for your well pump cut on and off?

Thanks

We did all 3, the pressure seemed normal on the cut off-on. It is still low volume. Maybe a little air still in the lines?

Would not be air...

Do you have any filtration system? Bleaching the well will cause the iron to oxidize and clogg everything up...

I would change all the filter elements in your system as lawrosa suggested. It doesn't take much to really clog them.
I have read that the tank bladders can take a beating when doing a well shock. Hopefully this isn't the case.
What does the gauge at your tank read when the pump kicks out? If you turn a tap on and let it run, does the gauge drop to the point where the pump kicks on? Does the pump recover the pressure with the tap still open?

Had the same thing happen. Shocked the well. Backed washed into the well. Ran water to all fixtures. Let it set over night. Ran the water until it was clear and the chlorine was gone (hours) then there was a problem. Pulled and cleaned all the aerators. Pulled the caps and flushed out the toilet fill valves. Was not having a good day and thinking oh crap what have I done. Don't know what happened but in a few days it was back to normal. Hope yours does the same.

Yes, the water conditioner was clogged with the iron after the bleaching. When we went around the unit, the water blasted through the lines.

Several years ago the pipes were full of iron, used a snake to open them. Bad iron here.

Meanwhile, is there any other way to disinfect the well from bacteria without chlorine?

Yes, other chemicals can be used but why? Chlorine is cheap, effective and commonly available.

Wondering about chlorine alternative because it oxidized the iron and created clog in the water conditioner - the source of the whole issue

I think the filter clogging is more a result of it's sanitizing properties and not the oxidation of iron and your filter would clog regardless of what sanitizer you used.
