thanks gary,....... I am also wondering about getting water to the well since house is 380' away, if i install a spicket at well and turn on, it won't work because pressure switch at tank under house won't change, correct? Is there a way I could bypass switch so pump would run?? (i guess i could just buy alot of garden hose...)
You don't want used chlorine to go back into the well (or into your septic). Running a line from an outside faucet to the well for 15-20 minutes is done to get the chlorine spread throughout the column of water in the well and to disinfect the casing above the water line. That's because chlorine (bleach) is heavier than water and will naturally sink to the bottom of the well (below the pump's inlet), not doing its job from the top down.
You can't run a garden hose to the well so you should pump water to above the casing and let it fall right back down the well for like 15-20 minutes before running the water to the house. You can't do that either.
Mix the bleach with water in buckets to dilute it and pour it down the well. Since you can't run water down the well, run an outside faucet/hose smelling the air exiting a bucket as you spray water into the bucket with your nose on the rim of a bucket or your head in the bucket until you smell chlorine. If no smell, mix up more bleach water and repeat until you do. Keep chlorinated water out of your eyes and off your clothes. You need a strong smell of chlorine.
Then you run cold chlorinated water into the house to all appliances and fixtures first using a glass and cold water to smell for chlorine. Run the water into the glass as you smell for chlorine with your nose on the rim. When you have a strong smell of chlorine in the cold at the kitchen sink, run the hot there for 2-3 minutes; you won't smell chlorine.
Then go flush all toilets and run cold water at all sinks tubs, clothes and dish washers, outside faucets and dump the ice maker and let it start drawing water and then shut it off.
Then start the clothes dish washer to get some chlorinated water into the plumbing to and in them, same for the dish washer. BTW, you by pass filters (or remove cartridges) and softeners etc. before running chlorinated water into the house.
After getting chlorinated water to all fixtures and appliances and running hot water for 2-3 minutes, let things sit for 15-20 minutes and then turn on all cold water faucets (one at a time) at all sinks etc. (no flushing toilets or running hot water) for 5-10 seconds and wait another 15-20 minutes (the longer the better) and repeat that for 2 hours (longer the better).
You do that to replaced the spent/used chlorine with fresh/stronger/free chlorine residual from the well and to flush out 'sediment' caused by the chlorine so it can do more disinfecting/sanitizing.
Then after the 2+ hours of running cold water every so often, run water outside where chlorine and such (rust) won't harm plants etc. until you can't smell chlorine in the water anymore. Flush all toilets and Spin the clothes washer and run the dish washer some and turn on the ice maker and when it has made some ice, dump it, that is to flush all chlorinated water from all appliances and pipes (outside faucets also).
Sometimes you won't be able to get all the chlorine out of the well for 3-5+/- days. Once it is gone, wait 7-10 days with none in the water before retesting for Coliform bacteria.
You must watch that you don't run the well 'dry'.
