Adrian was very nice, he was right on time and was able to answer all of my questions and navigate my issues. Katherine's really nice too, though we only spoke on the phone.

Very happy with the whole process. From Ethan coming out to test our water & discuss options, all the way through installation by Chris & Kevin, they made everything effortless on my part. All were very professional & efficient. Had a water softener & RO system installed on a rental basis so that all servicing is included and I don't have to worry about remembering adding salt periodically.OMG in the difference in the taste of my water. I always refrained from drinking my tap water, but now its so good I no longer need to purchase bottled water.I give total recommendation to Culligan Water of San Marcos.
