Our manufacturer is Farris Enterprises in Riverside, California. Our water treatment equipment is custom built specifically for Ohio Valley Pure Water. Why, because what works best in other parts of the country doesn’t work best here. Also because our water treatment equipment is not mass produced like our competitors this allows us to have full control of each USA/ Canada made components that make up our water treatment system. Our water treatment systems are built to last for years without all the bells & whistles. Each water treatment system comes with a manufacturer serial number for servicing & warranty purposes.
