Re: Water Pressure
If the presure at the service entrance is 60# there is no problem with pressure, and there shouldn't be a regulator. Generally they are not used until you get up to about 80# or more. You may not have a pressure problem at all, it may be a flow problem.
What size and what material pipe is coming into the home? What happens to it immediatly after it comes in? Does the "pressure" drop off when more and more fixtures are opened? If so this is a flow problem.
You could have copper or you could have lead. Both are good pipe materials, but the lead pipes were generally too small for modern homes, and no longer used because of health concerns. If it transissions to galvanized after it enters the home, or if the main line running through the house is too small, long runs, lots of bends, you will have issues.
Your local water utility should be able to look your plumbing over and give you an idea of what the problem is.
Without running a new line in from the street and re-plumbing your whole house, (this would be the best fix, but can be cost prohibitive) you may be able to add a pressure tank or tank with a pump.
Ask your utility for advice.
Waste not, want not.
Use it up. Wear it out. Make it due, or due without.
