I recommend Culligan right now because the customer service was amazing.
We had an issue with the resin getting out into our water system.
It plugged everything.
We called and Culligan was out fixing the problem the same day we called.
It is all fixed and our water softener is doing a great job.
Again the customer service was impeccable along with the service technician who fixed the problem.
Like knowing that my reverse osmosis filtered water is safe to drink and tastes great. Also, that the filters changed to new filters without cost every year.
