I need to connect to public water for a variety of reasons. City Engineering has told me I need to make the determination of tap size. House is ~ 0.3 miles from where meter will be installed on driveway/public street junction. City Engineering will make no recommendations on tap size but have given me pricing for 3/4", 1' and 1 1/2". It is obviously more expensive the larger we go. Does anyone have any recommendations on appropriate tap/pipe size and schedule to run this long length of pipe and maintain adequate flow?

I would go with a one inch meter and water service. But first I would want to know what the street pressure at the meter was. There will be some friction line loss in a service that long that would affect the pressure going into the house.
Call the water department and ask.
Then let me know. Good luck, Tom

Tom, water department tells me 80-90 pounds at the meter. 1" still sound good? Jim

Hey Jim,
Sounds great. As a matter of factyoumight have to install a PRV (pressure reducing valve) Check the pressure after you get the service run and reduce it down to a 45 to 60 PSI range remembering that the more pressure the more strain on the pipe joints, faucets and appliances that use water. Good luck, Tom
