What are the 4 types of standpipe systems?
Following are four types of standpipes that you will find in use:
- Wet system. Here, water is in the pipes at all times and is supplied by a water source.
- Automatic dry standpipe. Here, there is always air stored inside the standpipe at a constant pressure.
- Semi-automatic dry standpipe.
- Manual dry standpipe.

What do you pump a standpipe at?
The minimum pressure while flowing the required standpipe flow (500 GPM from the hydraulically most remote standpipe and 250 GPM from each additional standpipe, up to a maximum of 1000 GPM for a fully sprinklered building) shall be 100 psi at any valve outlet while flowing 250 GPM through each valve.
How does a standpipe work?
Standpipe systems are a series of pipes which connect a water supply to hose connections, basically an extension of the fire hydrant system. They are designed to provide a pre-piped water system for building occupants or the fire department.
What is a semiautomatic standpipe system?
Semiautomatic dry standpipe systems have mildly pressurized air in most of the piping that runs from a deluge (preaction) valve to the hose outlets, but have water in the lesser piping between the water supply and the deluge valve.
What is a semiautomatic standpipe?
• Semi-automatic-Dry standpipe, with empty pipe, is connected to a permanent water supply that is capable of. meeting flow and pressure requirements. It uses a device, such as a deluge valve, to admit water into the system. piping upon activation of a remote control device located at a hose connection.

How much do you pump a standpipe at?
What pressure should I pump my standpipe?
Standpipes are low-pressure systems. Depending on the year that the system was installed, the minimum required pressures are 65 and 100 psi.
How to make pipe stands?

What is a stand pipe?
Standpipe. Standpipes should be at least 2” in diameter and large enough to accept the washing machine’s drain hose.
What is standpipe system?
Wet and Dry Standpipe Systems. A Standpipe is a type of rigid water piping which is built into multi-story buildings in a vertical position, to which fire hoses can be connected, allowing manual application of water to the fire. Within buildings standpipes thus serve the same purpose as fire hydrants.
What is a dry stand pipe?
An air compressor specifically sized for your standpipe’s pressurization requirements.
