Well Sanitizing Instructions
Bypass the water softener, other filters or any purification equipment.
Remove well cover from casing and, if possible, measure the depth of water in the well (static water level) and the depth of the well (well depth can be determined using well log or other records). If you are unable to determine depths it is a general rule that is better to use too much sanitizer than too little.
Using the table below determine the amount of bleach needed then pour the mixture into your well.
Mix the water in the well by attaching a garden hose to a tap, running water from the well, through the hose and back into the well through the opening of the casing (Process known as ‘’backwashing’’ or ‘’backflush’’).
After approximately 15 minutes of flushing, if there is no chlorine smell or it is very weak, add more bleach and repeat step 4.
Flush for approximately 30 minutes and then allow for sanitized water to stand for at least 6 hours (overnight is ideal). Finally, open an outside faucet and flush system until water runs chlorine free. DO NOT continue to run pump if water does not flow! If your well yields a low GPM, flush system using a 20-30 minutes flushing and 20-30 minutes not flushing and repeat until water runs chlorine free). DO NOT run high levels of chlorine into septic system.
After water runs chlorine free, return all equipment to service position (water softeners, well cover, etc.).
