After you have decided it is time to your well out, it is now time to figure out how to do that exactly. You want it to pass a lab analysis..let alone have it be safe to drink from. Before you get started, you will want to get a pool cleaning kit, you can use this to retest the water to make sure that all the chlorine and chemicals are out. You will want to clean the entire well all at once, you cannot delay this project over time, that will allow the well to become contaminated. Be sure you have the time to dedicate to this project before beginning.
Cleaning out your well really is not all that complicated of a procedure. you will want to get a pool cleaning kit so you have the resources to test your water, to be sure that you get all the bleach, chlorine and anything else out that may be harmful to you. Really all that you will need to do, is take about a gallon of bleach, depending on the size of you well of course, and empty the gallon into your tank. After you have done that, you are going to turn your faucets on everything that has a water source in your home. Let it run til you no longer smell the bleach. Let the HOT water run, probably for about 30 minutes. Than you are going to let your tanks sit over night. DON’T USE ANY WATER. Make sure you have water supply to get you by until than. You can flush your toilets, just be cautioned that you could get bleach on your clothes, and we all know bleach doesn’t come out. Or on your sink, which can be harmful, obviously. By letting this sit overnight, you are just helping “sanitize”. In the morning, empty your hot water heater and turn off the refill valve until all of this is done. Take a regular hose, and clean out the tanks, be sure that it is being emptied somewhere safe to the environment…if possible. Once totally cleaned and emptied of the bleach water, refill.
Be sure through this process you are out there supervising, watch the pumps for overheating and do not leave anything unattended for long periods of time. Now after all the bleach is out, and you have tested the water, you now have a clean sparkling water supply. You may still want to install a water purification system to prevent from having to clean out your water well too often.
