A standpipe is a type of piping that in buildings is built into a vertical position. Fire hoses can be connected to these pipes, which allow water to be manually applied in the event there is a fire. Sometimes there is access to these standpipes on the outside of a building. In Portland standpipes testing and inspection is required because these pipes are an important access point for water.
In a building, standpipes are usually located near a road or driveway, so that firetrucks can hook up hoses to them. The standpipe will then extend into the building so that water can be sent to the interior of the building via the pipes. This saves time over the alternative, of, say, laying a firehose up a stairwell or something like that, where the hose would be likely to be heavy, be in the way, and slide down the stairs.
In Portland standpipes testing and inspection follows the National Fire Protection Association (NFPA) standards that provide requirements for the classification, identification, inspection, testing, and maintenance of standpipe systems. The testing and inspection is based on the type of hose connection that the standpipe system is set up to use.
There are three different types of standpipe hose connections. Standpipes are also categorized by type based on whether is water in the system or not. The pipes may be full charged with water or maintained without water until the water is needed.
A certified inspector will determine all of these variables and make sure the proper signage is in place. The number of valves and hose connections will be inspected and tested to make sure that your standpipe system works as it is supposed to when called upon.
