3/4" or 1" copper pipe
Posted by bay on September 25, 19100 at 15:46:07:
the water pressure at the city watermain is about 55 psi. the house is going to be offset back by 300 feet from the watermain. the builder has suggested 3/4" copper pipe, but I know there are going to be pressure losses due to the length of pipe (which will increase as the pipe ages). should I be worried, or would it be more advisable (i.e. more conservative) to suggest 1" or 1-1/4" copper so that pressure losses are smaller?
