Question 3

Pre 1960 Water System

Answer 3

Buildings built were limited to 150’ (13~ stories) and were required to have only a class I dry standpipes for department use

Class I systems are required in buildings with 4 or more stories in height

Standpipes are commonly located adjacent to fire escapes with 2 ½” outlets

Question 4

Water Systems: 1960 – 1974

Answer 4

Buildings required to have a combination system which is a 1 ½” interior wet outlet /w hose/nozzle designed for occupant use and a 2 ½” outlet for fire department, both supplied by the same riser

2 ½” outlets may have an attached hose /w an 1” straight tip and will be found in cabinets located in stairwells above the 4th floor

Drip Cocks: These hoses will often have drip cocksto prevent water from a leaking valve from entering the stored hose

Oriface plates: (washers?) – Designed to restrict flow (not regulate pressure) of water when the PSI exceeds 135; restricts flow to 200 GPM @ a minimum of 50 PSI residual pressure – Higher the system pressure, the smaller the diameter the oriface

These can be found soldered directly to the outlet, behind the gasket, or on the male end of the drip cock

These should be removed since it prevents us from obtaining the maximum flow, and possibly prevent us from obtaining the required nozzle pressure of 75 PSI as well as prevent adding a second line

The orifice plate may be removed by using a screw driver or channel locks.

If not removed, open the outlet all the way. If removed, outlet should be opened 1 ½” turns then adjusted from there
