  • POE sediment filtration — your first line of defense

    Around the country, our aging water delivery infrastructure is coated with sediment and scale from a century or more of buildup. Those same tuberculated pipes are constantly challenged by daily tie-ins, repairs, flow tests and fire hydrant use in most cities and towns. The result is that drinking water that left the municipal treatment plant at top quality arrives in users’ glasses — or in their ...
