What Our Customers Say ...

What my Father always said is that 'As long as we always treat our customers like family, we will be around as long as we want to be.' It's been 51 years so far so we must be doing things right!" Brian McCowin

McCowin water has been wonderful to work with! Brian, in particular is always very responsive, timely and organized. He’s very knowledgable with the products they offer as well as water purity in general. We have a purified water system installed in our kitchen with Insta-hot boiling water which comes in very handy almost everyday! We feel great knowing our family is drinking pure water without wasting plastic bottles or endangering babies/children with the choking hazards of plastic bottle caps. Thanks McCowin water for being a reliable vendor for us!
