Can I use this chlorinating liquid to disinfect my drinking water?
My water tester uses basic Clorox bleach, swimming pool chlorine will also work, dump the chlorine / bleach down the well vent and flush with some water, waiting at least 3 hours or over night will provide the best results then flush the system for 3 hours or until there is no bleach / chlorine smell and your well will be sanitized. If you want to eliminate some floaters and small sand from getting into your tank add a particulate or string filter prior to the tank, if a filter is added remember they need to be changed, get one with a clear filter housing and you may be surprised how much gunk a simple string filter can stop.
