Re: Water feed location to house
Poor water pressure in old homes is usually from the inside of galvanized water pipes corroding and reducing the inner diameter. SO a 3/4" line becomes more like a 1/2" line and 1/2: lines don;t flow more than 3/8".
The restriction being at the main is as likely as anything. But t's just a likely that all the piping needs to eventually be replaced.
I'm slowly replacing all of our water piping. One of our bathrooms upstairs has lower water pressure... guess what, it's the only bath that still has all the originl piping.
