WATTS® OneFlow® 7100488 Whole House Residential Anti-Scale System, 40 in H, 40 to 110 deg F, Domestic
WATTS® OneFlow® Whole House Residential Anti-Scale System, 40 to 110 deg F, 15 to 100 psi Working, 40 in Height, Domestic

- Chemical free scale prevention and protection and converts hardness minerals to harmless, inactive microscopic crystals making OneFlow® an effective alternative technology to a water softener for the prevention of scale due to water hardness
- Virtually maintenance free no salt bags or other chemicals to constantly add
- No control valve, no electricity and no wastewater
- Uses environmentally friendly green technology
- Improves efficiency of all water using appliances both hot and cold
- Simple sizing and installation
- Perfect system for towns or communities where water softeners are banned or restricted
- Residential systems do not remove minerals or add sodium to the water supply
- Residential systems can be installed as a pretreatment to reverse osmosis (OneFlow® should be the last stage in treatment unless a point-of-use system is being used downstream)
- Systems include a bypass valve for a simplified installation
- 1 in MNPT connection
- 6.5 to 8.5 ph
- 25 grains hardness
- Less than 2 ppm free chlorine
- 0.3 ppm maximum iron
- 0.05 ppm max manganese
- 1.3 ppm copper
- High levels of copper will foul OneFlow media and typically originates from new copper plumbing, wait a minimum of 4 weeks before placing system in operation, avoid applying excess flux on the inner surfaces of the pipe and to use a low-corrosivity water soluble flux
- 12 gpm maximum service flow
- Always install OneFlow® residential systems before the water heating device
- Standard/Approvals: ASTM B813|PROP65: This product can expose you to chemicals including lead which is known to the State of California to cause cancer and birth defects or other reproductive harm.

OneFlow® Residential Anti-Scale Systems provide a home with protection from internal hardness related scale formation on plumbing surfaces. Water using appliances and plumbing fixtures also enjoy a longer lifespan because hardness scale build up on internal parts no longer occurs. These systems are specifically designed for residential applications. OneFlow® Residential systems should be installed at the point-of-entry to a home to treat both the hot and the cold water. OneFlow® Residential systems prevent scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These crystals stay suspended in the water and are passed to drain, thereby having a greatly reduced ability to react negatively like dissolved hardness does. These systems require very little maintenance, no backwashing, no salt, and no electricity. Typical hardness problems, especially build-up of scale in pipes, water heaters, boilers, fixtures, and appliances are no longer a concern. OneFlow® Residential systems are not water softeners or chemical additives (like anti-sealants or sequestrates). They are scale prevention devices with proven third party laboratory test data and years of successful applications. OneFlow® Residential systems are the one water treatment device that effectively provides scale protection in the home and are a great alternative to water softening (ion exchange) or scale sequestering chemicals.
