When should a dry riser be installed?

Do sprinklers need risers?

Risers are typically used to support sprinklers, drip emitters, valves, backflow preventers, air vents, and just about anything else. (Lateral pipe/tube is the term used for the piping/tubing that carries water from the zone control valve to the sprinkler heads.)

What is the difference between a wet riser and a dry riser?

What is the difference between a sprinkler riser and standpipe?

A “wet” standpipe is filled with water and is pressurized at all times. A dry riser is a main vertical pipe intended to distribute water to multiple levels of a building or structure as a component of the fire suppression systems. The pipe is maintained empty of water.

What are sprinkler risers?

Fire sprinkler riser is like a bridge between your water supply and the sprinkler pipes in your building. That’s where water gets onto the building for fire extinguishing purposes. In actual sense, sprinkler riser is the main component of the sprinkler system.

What is the purpose of a fire sprinkler riser?

Still, there may be nowhere in a sprinkler system with so many necessary components per linear foot as at the fire sprinkler riser. In systems both large and small, fire riser assemblies prevent pressure from escaping the system, make repairs easier, and control the flow of water to sprinkler heads.

What are the different types of sprinkler system?

Back to Basics: Wet & Dry Sprinkler System 1 Wet systems. A wet system, as defined in NFPA 13, is a sprinkler system employing automatic sprinklers attached to a piping system containing water and connected to a water supply 2 Riser check valve assembly. 3 Ported check valve. 4 Dry systems. 5 Dry pipe valve.

Can you have a wet riser and Dry Riser in the same building?

Selling a piece of pro(Continue reading) Yes, you can have a dry riser and a wet riser in the same building, both are connected to the water supply. Most often the wet riser will cover the occupied spaces and the dry riser will cover the locations that are not temperature controlled.

What is the difference between a wet and a dry sprinkler system?

Most often the wet riser will cover the occupied spaces and the dry riser will cover the locations that are not temperature controlled. A dry sprinkler system works by having the system side filled with air and the supply side having water.
