Hi! I'm new to the forum and to 'water softeners'. The house I bought already had one. So basically I just cleaned the brine tank and put in a couple of bags of salt. From there I would put a bag of salt here and there...basically if there was no salt or it was low. Recently the water bill came and it was 8 times higher that usual. I found that the softener was draining continuously. I fixed the problem with a new 'seal pack'. After that I manually regenerate the unit. How long is the regeneration suppose to last, though? One hour later it's still regenerating... Also I would like to know how much salt should I put in the tank and how often? Thanks.
