[Sprinklerforum] Re: Fire Pump Drains

[John Denhardt]

Craig - 100% agree. All systems need a main drain piped to an acceptable place of discharge that can handle full flow with the fire pump system (if provided) operating.  There should also be a method to drain the fire pump system piping.  John John August Denhardt, P.E.

I’m assuming that’s taken care of from the casing drain on the pump?   Brian Harris, CET BVS Systems Inc. bvssystemsinc.com Phone: 704.896.9989 Fax: 704.896.1935     NOTICE - This communication may contain confidential and privileged information that is for the sole use of the intended recipient.
