  1. shouldn't you remove any whole house filters before running it to the house?

  2. there is no place to open on top of well pipe comes up  and goes to pump them in the tank like one next to you

    usually I just dump a gallon of bleach down the well. then run faucets in house then let it stand overnight. then flush out in morning. is it ok not to run the hose, like you did to recirculate the water ?

  4. Cliff P

    I live in SC may I ask where you get your water tested and how much does it cost? I was quoted 138.00 to test my water from one company. Any thing that I water get root rot…any and all help would be great!! Cliff

  5. I know this is a little late, but you want to run your well though a magnesium and iron filter, then through a sand filter where all the bacteria get trapped and eaten by the good bacteria, then though a uv sterilizer.  you should test for boron in well, it can kill you. anyways good luck.

  6. love your channel, lots of great info. question – can I use a 12 volt car battery to power my existing 12 volt well pump in lights out scenario? what do you think of this idea? seems like an inexpensive alternative. thank you for your input.

  7. I am in the business of water well service and repair and I can assure you that a gallon of bleach will not in fact chlorinate your water well. It might do a good enough job to get a sample test passed but will not work long term . You would have to use several gallons and pump it down through a trim pipe to get it all the way to the water source . We use a granulated chlorine that will fall to the bottom of the well,{ where bacteria mostly grows}, then dissolve and chlorinate the well from the bottom up. I highly recommend you call a professional for this action that will know how much to use and can inform you on how long the chlorine should sit in the well. But liquid will not work , it will run down the side walls inside the well casing and will dissipate before it reaches the water supply . We argue with our local health departments about this all the time , until we explain it to them.

    An inline UV disinfection system will treat water as you pump it without chemicals. Its a good option if you can afford it.

  9. FYI, Take all the faucet screens off before you do this! The screens will clog up with black slim coming off the inside of your cold water line from the well. Oh, by the way, don't forget to flush your washing machine our your significant other is going to be very very upset when she does the colored clothes. I found this out the hard way!

  10. All of my drinkable/cooking well water goes through my Big Berky filter in the kitchen. A gallon of bleach goes into the well once every six months. Then flush all the cold water faucets until the bleack odor dissipates.

    We have a lot of problems with iron bacteria in our well, so shocking it is a little different.  This last time that I did a shock, I filled a 1000 L tank with water and added 20 L of 20% bleach, mixed it well, then drained it back down the well.  This is to allow the shock solution to work its way into your water formation and really ensure that you have everything disinfected.  Let that sit overnight, then run the all the taps until you smell the chlorine, then lat that sit for the day, or longer if possible.  After that, you flush out as much as you can to the outdoors, you really don't want to run too much chlorine into the septic system.  Then flush out the taps and you're good to go.

    A gallon of household bleach may not be sufficient to get a full disinfection of the system, and I'd rather use too much than not enough.

  12. we do our well every spring and again in the late fall just to be sure its good

  13. It appears that the water did not run that long before you started putting it into the well, wouldn't the bladder tank have to be emptied, looks like its at least 60-80 gallons in the bladder. Once you do that how long does that last?

  14. chemical structure of sodium hypochlorite: Na.Cl.O, disinfectant.

  15. engineer775, Thanks for this video.  It is a "practical" way to save lives.

  16. SP3IIL

    well well, he disinfected the well well.

  17. Did I understand you to imply filtration will remove harmful bacteria?  
    Thanks for the video!

  18. Thanks for the video, I have read many ways to do this. My home inspector had advised to just run all faucets until the bleach smell came through, and then shut water off for 24 hrs, etc….he never mentioned running a hose back into the well casing directly off the bladder tank. If the bleach smell is coming through a faucet in the home (the last one on the line), wouldn't that mean the pump and bladder tank have already been saturated?

  19. E. coli is a coliform bacteria. Just a FYI.

  20. I have a issue with this. I see no issues with running this mixture thru any outdoor faucets. it is a big no no to add chlorine to a drain that empties into a septic system. It will kill all the necessary Bacteria needed for that system to function properly.

  21. Not scented or splashless, just the plain, cheap bleach.

    Scented contains chemicals that aren't FDA/EPA approved, and splashless doesn't dissolve properly in the well. 

  22. My well driller suggests using a PVC pipe to get the bleach past any brass fittings that may be at the head of the well. Bleach will eat the brass. 

  23. The place I used to work at the well got bleached every 6 months if it needed it or not used 12% bleach cycled it through the system let it sit for 24 hours. The 12% is nasty stuff eats your clothes instantly lol, the water is tested monthly never had any issues. I think its a good idea for anybody that's on a well should bleach it at least once a year its good preventative maintenance.

  24. sounds to me that the health dept is full of it red tape to make them more money.. I have a good friend that is a well driller and said that chlorine tablets is the best way to go when shocking a well especially if the casing is metal..we call it shocking a well the state I live in.

  25. I did this too but used a pool chlorine tab plus the gallon of bleach.

  26. Well, glad to see that I kinda did it right, but mostly by accident. Had a mouse get into the system, after closing the entry point I did a gallon of bleach, ran my garden hose back to the well to wash down the well casing. I wanted to keep the solution in the system as long as I could. The question I had was why did you specify just the cold?   I ran it through the hot as well, mostly because we have a tankless heater, and wanted to keep that clean.

  27. How does this work if your pump is 300' in the ground. Same procedures?

  28. how well would this do on one one of those open air wells in Africa?  And, is there a limit to the size of well?

  29. Our well is 80' to the bottom and 60' to the top of the water.  The well is in an underground stream.  I have put 3/4" pvv down the well to find the bottom, and at 70' I could feel the flow of the stream and it was very violent.  So if I put a toxin down the well, the next person down stream will drink it.
    So be careful.

  30. I've been meaning to ask if you have a UV Light on these systems?  They recommend do this if you pull the well.

  31. Thanks for the video and links.  We are just in the process of buying a home on a well and were thinking we would have to shell out $ to have the water tested and this kit price will save us a lot.

  32. Done this before works as advertised.  We bought a house that had sit vacant for a while. And yes the water made me sick. Did what you did in the video. No proplems after that. Curious about your flushing after wards. When I flushed my house plumbing the water came out with a black discoloration. Did you have the same effect?  Maybe my house was like that because it had set vacant?

  33. Should be using NSF certified bleach. Looks like house hold bleach was poured in. NSF tests the "other" ingredients and determines if they are safe for human consumption. Will what you did work? Yes probably but it isn't the right way. Certified bleach is not very much more expensive. Haas is the brand we use at my work as a water operator. 

  34. Speaking of well testing, we just got our results back a few days ago. It came back with great results on microbial and heavy metals EXCEPT arsenic. It had 47 units where they wanted to see under 10. Do you have a filter recommendation? We've been drinking out of it for 17 years now.

  35. Looks like you were using the concentrated Sodium Hypochlorite and sodium hydroxide (your label has the yellow band at the top like the one on my bottle I recently purchased).  I cannot find a percentage of chlorine on the label.  Doesn't the amount you put in a well depend on concentration and the volume of water in the well (pipe diameter x length – volume above the static water level + volume of all your plumbing)?

  36. Do you not have to calculate how much drawdown you have and adjust the amount of chlorine based on that?  A gallon wouldn't do much if your static water line was at 25 ft and the pump was at 125 ft, versus a static water line of 30 ft and a pump at 60 ft? Wouldn't that throw the concentration way off?
