Standpipes are a critical tool that require preplanning on first responding apparatus in order to be used effectively. The initial approval process for these systems is critical and the fire prevention bureau can assist responding crews by ensuring proper installation and maintenance of these systems.
Why are pressure reducing valves used in a standpipe system?
Due to the higher design pressures at lower floors, standpipe systems may include the use of pressure reducing valves. These valves must be inspected at the time of acceptance testing and on a regular basis. Responding fire fighters must be aware of these devices and their use.
How does a standpipe drain work?
A standpipe is an open-ended, metal pipe that can be screwed into a basement floor drain to permit the flow of water back up as high as necessary, thereby delaying or preventing a basement flood.
Why does a washing machine need a standpipe?
The standpipe assembly keeps the water level of the washer tub below that of the drain, preventing siphoning from the drain or sewer line back into the washer. When backflow does occur, siphoning can cause water to flow back into the washing machine from the drain, or out of the drain onto the floor.

What is the first step to understanding standpipes?
The first step to understanding standpipes is the technical data, the classes of standpipes, the types of standpipes, and the related NFPA standards and recommendations that go along with them. This is the first building block.
What is the NFPA 14 standard for standpipes?
There are two main NFPA documents that pertain to standpipes. The first and most well-known is NFPA 14, Standard for the Installation of Standpipe and Hose Systems. The second is NFPA 13E, Recommended Practice for Fire Department Operations in Properties Protected by Sprinkler and Standpipe System s.
How many feet of hose should be on a building floor?

Let’s throw a wrench in things, though. Best and accepted practice is to make your standpipe connection on the floor below the fire.
How do PRDs work?
PRDs reduce pressure and flow by interfering with or restricting the size of the orifice. They may be metal rings placed inside of the standpipe outlet to create a smaller orifice or they may be a stopper added to the standpipe wheel to keep it from opening past a certain point. There are multiple different types.
How is water introduced in a dry pipe?
Water is introduced via a dry pipe valve that must be activated manually. The two dry systems above have a permanent water supply. Finally, the manual dry system has unpressurized air in the system and has no fire pump or water supply, making it mandatory for the FDC to be used before fire attack can be made.

How high can a standpipe be?
Due to the pressure requirements standpipes are limited to a maximum height of 275 feet.
