Hello,
I am finishing my basement and have been planning to add a bar sink and a bathroom. Currently I have a one inch meter and a one inch pipe coming into the house. The plumbing inspector informed me that based on the number of fixtures that are in the house already, If i wanted to add any plumbing in the basement I would need to have the pipe running from the street into the house changed from 1" to 1 1/4". I did a little "googling" on water supply fixture units and found this table...

If I am reading it right, it appears that an increase in WSFU can be obtained by increasing the pipe size within the house, downstream of the water meter. Off the top of my head that doesn't seem to make sense that connecting a 1 1/4" pipe to a 1" meter and supply would help things, but I'm looking for any other option other than trenching out the front yard.
