Okay so I'm no plumber but I've worked tradey jobs most of my adult life and I can run some indoor pipe and hook up fixtures/filters, basic stuff. My question is in an area I have zero experience: our houses copper lateral. Our lateral run is LONG, the house was built in 1965 and at the time there was no water on the street in front of our house, so the water line is run through the backyard and all the way into the neighbors front yard on the street behind us. It's a 200 foot run of 3/4" type K copper. We've had the lines inspected and they are in good shape, not too much scale or deterioration, and our pressure is fine (55-60 psi) our issue is flow rate. We only get 3-5 gpm and it's fine for showers and 1 fixture at a time, but trying to take a bath while someone else is watering the yard does not work, lol.

My question is: does this seem normal for this long of a run with 3/4 pipe, or is there some hidden issue I'm not seeing? No PRV on the house, it's grandfathered in in my municipality (I've had the village out here and they know about it and it's fine).

There is now water access across the street in front of the house, so If we wanted to we could run new line through the front yard and do a bore under the street to tap in there. This is much shorter, more like 100 feet. So if things get worse, that's likely what we'd have to do. If we ever do it, we'd likely upgrade to 1 inch or 1 1/4 inch pipe to future proof. Just curious if this seems like a reasonable flow rate for that size and run and if there might be a hidden issue that we are all missing. Thanks for your time, I appreciate everyone's help here.

PS we are in Wisconsin, so lines are DEEP. 6-7 feet and come up through the basement floor.
