Reliance Valves Thermostatic Mixing Valves (TMVs) consistently blend hot and cold water to a safe, comfortable and stable temperature.

It is where above ground vertical supply pipes (system risers) connect the water supply to the fire sprinkler system’s cross and/or feed mains and where the system’s pressure and water are monitored and controlled. These system risers contain the pressure gauges, control valves, water flow alarms, and main drains for the sprinkler system.

Riser rooms serve the purpose of allowing maintenance workers and emergency personnel to quickly and easily access the fire sprinkler system’s controls for maintenance and emergency purposes.

As previously stated, local ordinances and your AHJ will likely have further details and additional regulations for your facility’s riser room, and it is of utmost importance you work with your AHJ as you design your riser room. This will not only prevent you from being hit with fines but will also ensure the safety of your facility and those inside.

The short answer to this question is: No. Neither the NFPA nor the ICC (International Code Council) requires that a proper riser room be provided for a fire sprinkler system’s risers. A system’s risers may be in a hallway or on the outside of a building. Where the reliance on a fire sprinkler system may not be as strong, a designated room may not be provided or necessary. However, if a riser room is provided, it must comply with ICC, NFPA, and local codes. More on that in a moment.

As many local codes provide more specific requirements that expand on NFPA, IBC (International Building Code) and IFC (International Fire Code) codes, you should check with your local AHJ to ensure that your property’s set up will pass requirements.

A properly designed, easily accessible, clearly marked riser room makes an enormous difference during an emergency and can be what prevents a small fire from becoming a life-altering tragedy.

Besides meeting NFPA standards, riser rooms must also comply with ICC’s International Building Code (IBC) and their International Fire Code (IFC), and unique and often more extensive requirements set by the AHJ (Authority Having Jurisdiction). Your local codes may dictate what must be included or excluded from your property’s riser room.

Once the air is displaced and the system pressure is sustained, the valve plug seals and prevents any water from escaping from the system. This valve can also purge air that may be in the water system. Model can be disassembled for maintenance.

Riser rooms do not technically have to be true rooms, according to the IFC (International Fire Code). Still, there are regulations for the environment in which the fire sprinkler system’s risers are kept to ensure that the pipes remain sound, operational, and readily accessible.
