This new and easy Water Valve and Filtrations system protects your office for years and years with little worry.  No need for a plumbing bypass, the filter can be changed by turning the knob on top to turn off the water flow so the filter can be changed.  Unlike most Water Valves installed in offices today, this one has a ball valve that is not susceptible to wear down failure by the hard minerals, sand and grit from your water source.  SIMPLE, EASY and RELIABLE!
