FAQs

What is the primary purpose of this backflow preventer?

This backflow preventer is designed to protect potable water systems from contamination by preventing the reverse flow of non-potable water due to backsiphonage or backpressure. It is used in health hazard applications.

Is a connection kit required for the flood sensor to work?

Yes, an add-on connection kit is required to activate the flood sensor's alert capabilities. Without the kit, the sensor is a passive component and will not communicate with other devices.

What types of alerts can the flood sensor provide?

When paired with a connection kit, the flood sensor can relay multichannel alerts such as calls, emails, or texts to notify personnel about potential flooding events.

What materials are used for the main components of this assembly?

The housing and sleeve are constructed from Type 304 (Schedule 40) stainless steel. Link checks utilize Noryl® and stainless steel, while check discs are made from reversible silicone or EPDM.

What is the maximum operating pressure and temperature range?

This backflow preventer has a maximum working pressure of 175 psi (12.1 bar) and operates within a temperature range of 33°F to 140°F (0.5°C to 60°C).
