Probably an often asked question, but my house is on public water and the pressure is very poor. There is a noticeable drop when more than one faucet is on, however it's still useable. This is a nuisance and I was wondering what I can do to fix this. Specifically I need to fix the supply to the shower, which is driving me insane. Somebody recommended I upgrade these pipes to a larger diameter wherever they are visible. Will this work even though there will still be "bottlenecks"?
Any ideas are greatly appreciated.
