Backflow Prevention
Backflow prevention devices keep contaminated water from flowing back into potable water supplies. They're required by code wherever cross-connections exist, such as boiler feeds, irrigation, fire systems and process water.
Backflow Device Types
- Reduced pressure zone (RPZ) assemblies – high-hazard protection
- Double check valve assemblies – low-hazard protection
- Pressure vacuum breakers – irrigation
- Atmospheric vacuum breakers – simple point-of-use
- Repair kits and test kits – maintenance and annual testing
Choosing a Device
The hazard level and local code determine the device. Size for flow and pressure loss, and plan for annual testing access.
Centro supplies backflow prevention devices and repair kits.

Boiler Accessories
Boiler accessories keep boilers safe, efficient and compliant. Controls, valves, gauges and trim are just as important as the boiler itself.
Accessories Available
- Low water cutoffs – protect against dry firing
- Safety relief valves – overpressure protection
- Pressure and temperature gauges – monitor operation
- Controls and thermostats – efficient operation
- Gauge glasses and blowdown valves – maintenance
Choosing Accessories
Match accessories to boiler type, pressure and code requirements. Test safety devices regularly.
Centro supplies boiler accessories and trim.

Boilers
Boilers provide hot water and steam for heating, sanitation and industrial processes. A properly sized, efficient boiler lowers energy costs and supplies reliable heat across commercial buildings and production facilities.
Boiler Options
- Electric boilers – emission-free, compact and quiet
- Gas boilers – high output and fast recovery
- Hot water and steam boilers – space heating or process loads
- Condensing boilers – maximum efficiency for hydronic systems
- Boiler accessories – controls, valves, gauges and trim
Choosing a Boiler
Size the boiler to your heating load or steam demand, and consider fuel availability, efficiency, footprint and emissions rules. Water treatment and regular maintenance protect efficiency and extend boiler life.
Centro can help you specify boilers and the accessories needed for a complete installation.
