I had Culligan put in a water softner 16 years ago and I must say their product lasted a long time. The service guy came in and retro fitted everything, including to make sure the kitchen tap cold water is not through the water softner. The quality was ok, no leaks ever. There were just too many un-necessary joints. The softner unit timer failed after about 10 years, but I was able to manual regenerate the brine through the back of the timer. Culligan told me if I can regenerate the softner and you're still getting soft water, there's no need to replace. I think this is important that they are being honest and not try to sell me something new.
