The well at the home I recently bought has coliform bacteria in it (it tested negative for E-Coli though, which is good). I'm looking to "shock" the well. I looked up quite a few instructions but I want to make sure I take every precaution. First I know i should shut off the cold water tube going to the hot water heater. Do I need to bypass the water softener as well? Lastly I have another blue tank in the basement that I'm not sure what it is (attached pic). Do I need to do anything with it? What is it? Other than these questions the process seems pretty simple, directions straight from the county.
1.) Shut off hot water tank
2.) Pour 2 gallons of unscented household chlorine bleach down the well.
3.) Fill well with water from the hose until you smell chlorine. Turn off hose.
4.) Run water in every faucet and toilet one by one until you smell chlorine. Make sure to shut off faucets when done.
5.) Pour in one more gallon of chlorine in the well and close it up.
6.) Wait 24 hours
7.) Turn on outside water faucet allowing the chlorine water to flow out in a safe place. Wait until you no longer smell chlorine and test with a chlorine strip.
8.) Turn back on hot water tank.
Everything sound right with that? This is my first time cleaning a well so I want to take every precaution to ensure I give myself the best chance of killing the bacteria.
Thanks in advance!!
