Putting Clorox into Sealed well?

[junior123]

Need a little help. Don't know much about wells. We have a new deep well that has a sealed cap on it (see picture). I tested water positive for bacteria and need to add some Clorox. I can't figure out what is the best route to get the Clorox in. I poured into the port hole with the plastic cap on it, but I don't think this got into the actual well, just went around the casing. Should I just remove the PRV off the top and pour in that way? Does the whole cap have to come off and s there a trick to that? Thanks for any help!!!

Please hang in there. We have a few specialists who deal with wells and contamination, but they are out in the field often. They will come in here soon to get the answer you need.

That little grey plastic thing sticking up is an air vent. Unscrew it from the well seal and you will have a 1/2" or 3/4" female threaded hole to work with. You can pour chlorine down that hole, but not the one with the pressure relief valve attached. You will also need to connect a water hose to that hole and circulate the water and chlorine around to get it to the bottom of the well and in the pipe.

Thanks Valveman! I ended up pouring down into the vent hole like you suggested. It took a couple days and then we started to smell the Clorox.
2 quick follow up questions:
1. When you say connect the water hose to this spot do you mean connect a water hose to dump water back down this vent hole to circulate the water?

2. I thought I would be able to run a hose after I circulated through each fixture and vacate the Clorox, but it seems to be hanging in there. Do I just need to wait it out until the Clorox leaves the system or should I try to run a hose and let it run until I don't smell Clorox anymore?

Thanks for the help!

I add a little Vinegar first to decrease the PH. I attach a hose to the 1/2" vent hole and circulate the Vinegar for about 20 minutes. Then I add Chlorine and circulate it for about 20-30 minutes. Then I open every faucet until I small chlorine and shut off the faucets. I let it sit in the pipes for an hour or two, then flush the chlorine out of the well through an outside faucet or two, so I don't get Chlorine in my septic tank. After the Chlorine smell is about gone, I flush fresh water down the well for 20-30 minutes to get the chlorine off the pipe and couplings above the water level. Then I flush the well with outside faucets again until the smell is almost gone.
