You will get more water with a larger pipe and if you have a 1" pipe from
the main to the meter, but a 3/4" meter, you would have the option of
"upgrading" to a 1" meter. This all would come in handy if you want a lawn
sprinkler system or outside water faucets. Then in theory you would have
more water flow inside your house while watering outside and more water flow
outside.

In my case I want to eventually install a lawn sprinkler system, so I would
prefer a 1" main.

Note: My city requires a 1" main for new service and I think replacement of
existing mains as well.

Just wondering if there is any reason to use 1" pipe when replacing my
service line. I'm thinking there isn't since 3/4" pipe is running through
the slab to the main shut off valve, and I won't be replacing that.
