We got David's number as a recommendation from a friend, because the water softener on our new house was busted - Googling "Water Softener Repair" got us nowhere. David was honest with us and let us know that it could be rebuilt for a little more than $500, but we decided to replace it completely since it was also rather old, and we also asked him to service our reverse osmosis unit at the same time. He was prompt, quick but thorough for all of our appointments, and took the time to explain to me how to program the machine if I wanted to change the settings. I would recommend Pacific Water Conditioning to anyone looking for an honest water softener appliance repair person.
