i‘m installing copper pipes to my bathroom and i know that the standard size to supply water to faucets and showers is a half inch. but would spending a little more now and getting 3/4 inch pipes be better in any way or just a waste of money and water? the reason that i ask this is because when i look at the inside of my old pipes (galvenized), there is barely any room left from all the mineral or whatever build up. that‘s why i was thinking if i were to install larger pipes now, wouldn‘t that increase the life of my pipes? does copper pipes even get build up like iron? what exactly happens to copper pipes after 40-50 yrs. (i‘m told that‘s the average life).
Copper pipes do not get the build-up you see in your iron pipes.
its common to use 3/4 as in comes into your home after that you take off 1/2 to furnish the rest of the house.you will not get a build up with copper .as with galvenized because of a chemical reaction that takes place in the lines over time as minerals react with the galv.not so with copper. 65
