Domestic water bypass

A domestic water bypass allows the Uponor AquaSAFE fire

sprinkler system to operate properly even when flow-restricting

devices, such as water softeners and filtration systems, are

present in the home.
When a sprinkler activates and water pressure drops

significantly, a PRV opens and routes the water directly to

the sprinkler system, taking the path of least resistance, thus

avoiding the flow-restricting device.
The PRV opens only during sprinkler activation and not domestic

use. Therefore, the flow-restricting device does not negatively

impact the water supply of the fire sprinkler system and allows

homeowners to use regular residential plumbing devices versus

commercial devices.
Note: When the flow switch detects water flow through

the bypass, it can activate an optional alarm, which alerts

occupants that the sprinkler system is operating.

Bypass components

• PRV
• Pressure gauge
• Alarm flow switch (if required)
• Electric alarm bell, horn or strobe light (if required)
• Required piping and fittings
