Absolutely wonderful experience. Phil of Berks Water Tech submitted the most competitive, all-encompassing quotation of three companies. When we built our home over 20 years ago, we are on well water so he took all the possible variables into account when he was setting us up--including UV light, reverse osmosis system, etc. He services it annually. Berks Water Tech is a professional, friendly organization to deal with. Easy to contact, knowledgeable, on time, and a pleasure to have in our home.
