Very knowledgeable and helpful! I have called twice to get information about RO and DI filters for my home business, and both times I quickly got a support rep (I was speaking with their COMMERCIAL support reps) who gave me great and honest information. I say honest, because I was somewhat knowledgeable before I called (so I would know if they were trying to deceive me) and because they were not trying to sell me more expensive or unnecessary equipment, like some of the local water service companies (although my local companies were also very nice and helpful, they just don't seem to be quite as knowledgeable). All I would say is that it helps to know your stuff before you speak to the reps at US Water Systems, or just be patient as you learn and try to figure things out, because you might get lost, overwhelmed, or not provide them with the necessary information, if you are new to water purification. Enjoy the process!
