i've had a master water system installed for six years and it's never worked well. i blame the installation, lack of info from installer, and subsequent lack of service... i do not blame the manufacturer. the system is well water into a filter that is labeled model# 255/440i (NS-20T printed on tank). there is some sort of "sacrificial media" in there, i saw the guy put it in years ago, but i don't know what it is. i suspect calcite, but it backwashes with a brine solution. i've read that calcite filters don't need brine to backwash, so i am confused as to what the media is. is there a way to find out? the second filter is 268/440i. Don't know what this one is, maybe a sediment filter. how do i find out? (MBA-MM-10-1 is printed on tank). or maybe its the plastic balls? again, how do i find out. of course, if it were the balls it would need to be attached to the brine reservoir, no? i have had it serviced a couple of times, but each guy bashes the last and complains about the installation. then a nationwide chanin quoted me 8000 to replace it. honestly, i've lost the trust and desire to have someone else service the system. i often wonder if they purposely do a poor job to convince me the the system needs to be replaced. i would like to service this thing myself, clean out the filter screen, hose, and replenish the media as required but have found not so much info on trouble shooting and maintenance. any help would be immensely appreciated. thanks thanks

Hello everybody. I have a Cullingan Mark 100 water softener that has been giving me problems for the last couple years, The unit is about 8 years old and I have called the Culligan man out a couple times to find out why we have no soft water And each time they inform me that there is no brine draw then clean or replace the eductor and leave after ensuring that there is vaccuum on the brine line. all appears to work properly for a short while but then we loose our soft water only to go through the whole procedure again. (I haven't added salt for 2 years) This time I bought an eductor kit and installed it but still have no vaccuum on the brine line. What should I look at next? Any suggestions would be appreciated. Jim
