FAQs

What is the primary purpose of the Colt C400 RPZ backflow preventer?

The primary purpose of this 2 1/2 inch Lead Free Reduced Pressure Zone (RPZ) backflow preventer is to protect potable water systems from contamination due to reverse flow caused by backsiphonage or backpressure.

What type of connections does this backflow preventer use?

This C400 series assembly features grooved inlet and grooved outlet connections, which are designed for easy installation with compatible grooved piping systems.

How does the flood sensor function, and what is needed for it to work?

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate the sensor and enable communication for alerts, an add-on connection kit is required. Without this kit, the sensor remains a passive component.

What are the main materials used in the construction of this assembly?

The housing and sleeve are constructed from durable Type 304 (Schedule 40) stainless steel. Link checks are Noryl® and stainless steel, while elastomers are EPDM, silicone, and Buna 'N'.

Can this backflow preventer be installed vertically?

This backflow preventer is approved for horizontal installation. It can also be configured for N-pattern horizontal or Z-pattern horizontal installations, but not vertical.
