What issues will I have going from a 3/4 to a 1 x 50‘ run of copper pipe?It‘s going under the driveway, hopefully forever and just wanted to make sure there would be room for expansion/improvements of the cabin in the future. What pressure/flow, problems/benefits will I have? It will be burried in sand, compacted then paved over.
It would not affect water pressure.
That is not a big change .Sounds big cause its twice the size . But you will be downsizing it after it comes back in .Good idea really .
There will be little change obvious You will gain volume over a slight drop in pressure in that sectionWhen you return to the domestic connections they will either be 3/4 or 1/2 Mains pressure will resume at these points Ideally you can use plastic coated copper for buried pipes It can avoid corrosion in the longer term Sounds like you are doing the right thingHave a beer when you finishThat makes it work better
