Backwash Well
Potentially dumb idea. I haven't found any guidance on this yet, so I'll try asking you all!
I have a 6" well of unknown depth; no records and my 30ft rod didn't hit bottom, and I'm not equipped to pull the pump.
Issue I am having is iron bacteria. I have disinfected the well a few times over the years, and it feels like it's making the situation worse. I used a test kit to hit concentration, recirculated, etc... and the problem goes away for a few weeks or months, then seems to come back worse.
What I am considering is using a 1,000 gallon water tank I have access to, to backwash the well. The plan is to fill the tank, disinfect the water, wait a few days to let the well recover (if it even does, I've never had a supply issue), disinfect the well following normal procedures, then drain the tank back into the well (at concentration levels).
My concept idea is to get that bleach water into the pack(?) around the bottom of the well and disinfect it. I don't know if this is going to solve the problem entirely, but if it gives prolonged remediation, it might be worth the effort every couple of years or whatever?
Lemme know what you think.
