2) Add approximately one gallon of household bleach into the open well casing.

3) Attach a hose to an outside water faucet and run the water back into the well casing.

4) Once the odor of chlorine is noted coming through the hose, flush the inside of the casing thoroughly before shutting off the water.

5) Remove the hose from the casing and replace the sanitary well seal being careful not to get dirt or debris into the well.

6) Run the water through all of the taps in the house until you can smell the chlorine.

7) Shut off all taps and allow the water to set overnight.

8) The next day, remove all faucet aspirators and bypass any water filters before flushing all taps.

9) In some water supplies, the chlorine may remain in the water for a few days, so don't be concerned about a lingering odor.

10) Good Luck!
