What is a fire pump test header?
What is a fire pump test header?
A test header allows for the flowing of large quantities of water through multiple hoses. The fire department connection (FDC) allows the fire department to supplement the fire protection system in the event of a fire (refer to the August 2006 Quick Response newsletter).
What is a hose header?
A header hose (5/8″ or 1/2″) delivers water from the source to the watering system. Compression ends, sold separately, are used to seal the end of the header hose.
What is manifold for fire pump?
hose valve test manifold
The traditional method of measuring water flow during a fire pump test has involved the use of a hose valve test manifold, intended to be mounted on the exterior of the building, where 50-foot 2-1/2 inch hoses are then attached to allow for water flow where measurements can be made to the water streams.
What is a churn test on a fire pump?
The fire pump churn test is done by running the fire pump without the water flowing. The churn pressure is measured. This is a measure of the pressure the pump delivers when it is running without water flowing through it.
Is a fire pump test header required?
Where a fire pump test header is installed, NFPA 20 requires that it be installed on an exterior wall or in another location outside the pump room that allows for water discharge during testing.
How often should fire pumps be tested?
Therefore, it’s your responsibility to check your local guidelines often to prevent an accidental violation.

What is a forward flow test on a backflow preventer?
In an opposite manner, the forward-flow test for backflow preventers was created to ensure the sprinkler system can be served by enough water in a fire condition. Reduced pressure zone backflow preventers are particularly susceptible with the potential for development of closed memory in their spring mechanisms.
What is the hose connected to the manifold?
The hose you are speaking of is technically part of the PCV system. It supplies the crankcase with filtered air that mixes with the blow-by and then is re-introduced through the PCV valve into the intake manifold at high engine load situations.
What does LDH stand for in firefighting?
The adoption of large diameter hose (LDH) – hose greater than 3½ inches in diameter –by fire departments has helped improve firefighters’ ability to provide water supply for fire suppression operations.
What is a LDH manifold?
A manifold that features an LDH inlet and wyes off to multiple 2½” gated discharge ports, usually three ports. This manifold is used at the end of the feeder line and supplies multiple discharge lines. A manifold that features an LDH inlet and two LDH gated discharge ports.
How often should a fire pump churn test be performed?
According to NFPA 25, fire pumps must be tested on both a monthly and annual basis to ensure that they will perform as designed. These two different tests are referred to as a monthly “churn” test and an annual flow test.
How many hours diesel driven fire pump should run?
