We are in business to help our customers solve their water quality problems - we believe that selling equipment is incidental to that mission, rather than the mission itself.  Replacing older equipment is often not necessary, and we help our customers understand the trade-offs between cost and reliability.  To a surprising extent, water quality varies between private wells, even wells in close proximity to one another.  We take the time required to understand the underlying chemistry and specific requirements to arrive at the best solution for each customer.
