sanitization of used Mark 10 with standing water
I have an opportunity to get a used Culligan Mark 10 water softener from a friend.
My concern is sanitization. It has not been used for a few years, theres standing water in the tanks.
So...I can handle the move and the plumbing but what about sanitization? I can empty out the brine tank no problem and bleach it.
The install manual I pulled online says you can sanitize the resin as well using bleach after regenerating once to remove iron (shouldnt be a lot in this water) and then by pouring a cup of bleach into the brine chamber and again manually recharging.
Think this would do the job???
