Low water pressure; new pipe leaching?
Finished renovating a house, we bought but had never lived in...and have bad water pressure. Just learned our pipes connecting the house to the town water main on the street are galvinized steel and really old. Water company measured water pressure on the street outside of our house and it is is 55-60. Water pressure just inside the house is 35. We are going to replace outside pipes to the house -- with copper pipes, probably about 60 feet worth of pipes. The new outside pipe will be 1 1/4 inch type K copper pipe. Plumber also will replace about 10 feet of old pipe inside the house with 1 1/4 inch type L copper. This will connect to new and existing 1 inch copper pipe inside the house. The ph of city water is about 7 or 7.1. Probably good to get rid of old pipe anyway, but does anyone have a view if this will help our water pressure? Also - anything I should worry about with new copper pipes leaching? We have water filter at kitchen sink. Thank you.
