My original water system in the house was a whole house reverse osmosis system, and it was installed by another company. Clearwater Systems of Lynden, Washington bought that company out. The problem that I encountered is that Clearwater Systems of Lynden, Washington prefers to do "point of treatment" systems, and not the original whole house system. This is like having a min-system at each point, which is not really practical when you have six bedrooms and four bathrooms. As a result of this, they could no longer provide the full range of services that I needed. They are nice people, and all that, but I had to go with another company that can provide the full range of services, pumps and filters that I need.
