What are these crazy looking multi valve outlets you see on the outside of some buildings ? They are for Fire Pump Testing

You have probably walked by them and not noticed them but other times you may have with any where from 2 to 6 or more  little individual hand valves on them depending on the size and volume pump puts out

They serve an important purpose they are used to test the Fire Pump which boosts the pressure to sprinkler system which protect buildings. Since water can not be run thru the sprinkler piping while testing the pump this bypass valve arrangement is installed  and hoses attached to allow the water to flow towards a street drain.  the valves can be individually open and closed to allow pressure against the pump while being tested  . Got to see a test at a large storage facility once and was very impressive .


Check out this Youtube Video of a test being performed by a contractor




So now you know what those weird valves are for.
