Max Flow Through Water Main
Hi there wallies,
As with heating there are max flow rates for hot and cold water pipes in homes. Honestly I went off of feel and rules of thumb from years in the field when piping domestic water lines, haven't had an issue yet. I have a client with a specific sized water main and he wants a filter (most likely sand media filter) for all incoming water. With the size of this home and the MANY bathrooms its impossible to say lets take a worst case load (gpm) and use that. His fixtures can surely out draw his piping.
The water main is 1 1/4 in copper. With 60 psi street pressure, and max flow, what flow will this pipe support? I came up with a conservative number of 25gpm. Is there a size and gpm table somewhere on engineering toolbox? While I dont want to over engineer his filtration, I also dont want to under design.
Thanks in advance.
