Are there drainage requirements for automatic air vents?

No. Generally speaking, most automatic air vents don’t come with drainage requirements since their primary purpose is to exhaust air from the system.

However, that doesn’t mean that there aren’t options available on the market. Since the vents will discharge water after trapped air has been released, a connection to a drain may be necessary in some cases. If a collection pan isn’t provided, or isn’t meeting your needs, speak to your Bison Fire Protection expert about a solution.

Are two pressure regulating valves required for systems that serve multiple downstream hose connections?

Yes. By installing two Pressure Regulating Valves (PRVs) in a system, you’re guaranteeing that at least one of the two systems will work even if one part of the system is unable to reduce the pressure. Installing two provides an additional level of security, assuming that if the valve does fail, it will do so in the “open” setting according to industry standards.

Keep in mind that each valve will typically have a minimum fixed loss of 10 psi, but should be verified by a qualified technician.

Do sprinklers need to cover the entire area at the top of a stair shaft even if the stairwell is noncombustible?

Yes. Sprinklers must be installed at the top of the shaft, and under the first accessible landing above the bottom of the shaft.

After all, the point is to provide adequate sprinkler coverage for every area of a building or warehouse, which includes ensuring all stair shafts - even ones built with noncombustible material - are properly protected.

Can I install a reducer (increaser) on my fire pump?

Yes, an “eccentric” reducer is permitted on the discharge side of the pump, so that you can use either an eccentric reducer or a concentric reducer. However, it’s critical to only use your reducer on the discharge side of the pump; otherwise you risk allowing air pockets to enter the fire pump, which could cause a small explosion.

If you have questions about your fire pump, contact a Bison Fire Protection expert today.
