Was it ever permitted for a 1000 GPM pump to be supplied by 6" piping?
Also, was it ever permitted to put a CONCENTRIC 8x6 reducer on the
suction flange of a pump.
We have an existing project where the owner was hoping to remove the
pump and to supply from city water. I informed them that the water
pressures on site were not compatible. They also have a pump that has
been requiring a lot of maintenance. As I looked at the as-built plans
(yeah, miraculously they had them for a building built in 1988), it
shows a 6" supply for the 1000 gpm pump and the concentric reducer on
the suction flange of the pump.
In the most recent editions of NFPA 20, a 1000 gpm pump needs an 8"
suction line.
