The two gentlemen that installed our unit were very professional and kind. Though we've only had the system for a few weeks, we are quite happy with it. Our experience suggests this is a great local company that strives to put the customer first.


First thing we did when we bought our house was purchase system with Hague, now nearly 10 years later we appreciate every interaction we have with them.


I had my system serviced today. The technician was professional and thorough.
For a wonderful water system I recommend Hague Water to everyone.


Hague is THE best water company on the central coast. I spoke with every single local company and was blown away by what Hague had to offer.


Worked with Hague for over two years with a commercial level RO unit. They have the highest level of customer service, any time we needed help or anything needed to be worked on they came incredibly fast and made sure our unit was working in tip top shape. I highly recommend their services!


Excellent service: arrived on time, checked all my Hague appliances, made sure all was right after filter changes, and done in less than 30 minutes. Perfect!
