I have an old house - circa 1920, and have 1/2" water pipes throughout
the house, and a 3/4" main that was replaced within the past 5 years.
My problem is that, with 1/2" pipes, a faucet turned on downstairs
will affect the flow while someone is in the shower upstairs.
Apart from changing all the pipes to 3/4" to increase overall flow
throughout the house - an option that is going to be extremely
expensive and invasive, I would like to see if there are any other
options. For example, is there a whole-house pump that I can attach
near the main that can increase the water pressure in my house in
order to avoide the impacts I mentioned above?

I just replaced hot water pipe that was from the 40s that was so
corroded only a dribble came through, you couldnt even see through a
4" section cut out. Increasing pressure on old pipe is asking for
trouble, Replacing with Cpvc and Pvc is easy and cheap. Usualy the HW
gets clogged first, but it could be another issue, a clog somewhere.
Is HW ok, is it all the same age, what is water pressure incomming.
Before investing in any pumps or re-piping, I would do some
investigating and experimenting.
Get a pressure gauge of some kind. There are ones that will
attach to a hose bibb, for example.
Measure the pressure as close to where the service comes in
as possible. See if that remains fairly steady when water
is used elsewhere.
Follow the service line in the house to see if there is a
pressure reducing valve (regulator).
Find out what kind of piping was run to the various fixtures
(baths, kitchen). If it is galvanized iron (common in 1920),
no amount of pumping will help if they are clogged with rust.
If the piping has been replaced, look for some remnant of
iron piping (just one fitting would be enough) which could
be affecting the flow.
That's just a starting point. Do the detective work and
post back what you find.
