FAQs

What type of fluid hazards does this backflow preventer protect against?

This FEBCO backflow preventer is specifically designed to protect water services from high hazard (toxic) fluids in industrial installations and applications.

What material is the body constructed from and what corrosion protection does it offer?

The body is made from lead free ductile iron and features a patented 3-part ArmorTek® epoxy coating system. This coating is engineered to limit both microbial induced (MIC) and exposed metal substrate corrosion.

Does this assembly include a flood detection system?

Yes, it integrates a flood sensor with SentryPlus Alert® technology. This system detects continuous discharge from the relief valve, providing alerts for potential flooding events.

How can maintenance alerts from the flood sensor be received?

Alerts can be relayed via a Sensor Control Monitor, integrating with Building Automation Systems (BAS) through RS-485 Modbus, or through the Nexa® platform using Wi-Fi connectivity.

What is the relief valve discharge rate for the 2 1/2 inch model?

For the 2 1/2 inch size, the typical relief valve discharge rate is 55 GPM (gallons per minute). This information is helpful for proper floor drain sizing.
