Marketing InformationThis residential OneFlow(R) anti-scale system, model OFRES-0935-K, provides a home with protection from internal scale formation on plumbing surfaces up to 12 GPM. Water using appliances and plumbing fixtures have a longer lifespan because hardness scale build up on internal parts no longer occurs. This system is specifically designed for residential applications and includes a WiFi enabled monitor to send email and/or SMS alerts when media replacement is due. This system should be installed at the point-of-entry to a home to treat both the hot and the cold water.
