Unless you really enjoy reaching deep in your pockets for very expensive service calls, stay away from Culligan.
Anything you ask them for after the warranty expires is ridiculously over priced.
They really take advantage of customers that are concerned on having a safe & healthy water supply.
We had an "O" ring to be replaced as the system was leaking, well how does $125 sound?
We needed to replace the membrane filter on our Culligan reverse osmosis system, $125 plus $115 service call.
You can buy an alternative filter that is compatible to the original for $33 on the net.
Supplies such as potassium permanganate necessary for regeneration of the tanin filtration system is 3 to 4 times more expensive when purchased from Culligan.
A month after having our $6000 system installed we referred them to our neighbour, what a mistake that was. Today both of us regret buying from Culligan, and our neighbour no longer speaks to us.
I should have chosen Kinetico over Culligan.
