How do you increase the water pressure in your home?

How do you increase the water pressure in your home?

Not quite that simple Dag,
First I have to know what water system you have in your home. City water or are you on a well? Did this loss of pressure happen suddenly or did it come on gradually? Details, Dag, I need details! Regards, Tom

Same questions. City water. Low pressure when running two showers at times, and planning to add another full bath to my house. Tankless water heater for hot water. Large enough for two showers and one appliance.

Prerequisite for good "pressure" is to have properly sized pipes throughout your house. Besides questions asked in posts above, can you tell us how is your house plumbed ? Thanks. Milo

Yes, my house was built in 1963 and has steel plumbing. I live in Houston and have found that everything in my house either met or exceeded code at the time. Which pipe would be the best to measure to determine the size in my house?

my house was built in 1963 and has steel plumbing. Which pipe would be the best to measure to determine the size in my house? Milo wasn't asking about a single pipe. He was asking about your piping system. You do not have steel pipes your house is piped in galvanized iron and you don't have a pressure problem you have a volume problem.
You have to realize then difference between pressure and volume. It's exactly the same as the difference between voltage and amperage. For instance if your pipes were too small you could still have lots of pressure in them, however if you didn't have the volume necessary to back it up you would lose both pressure and volume. Your system must have both to operate efficiently.
What's happening to you has already happened to me in my 1950s house.
Over the years iron oxide, (rust) builds up in your pipes. My 3/4" galvanized pipes had rust built up to where it choked it down to the size of a pencil. There is no easy fix to this. I had to repipe my house in CPVC and that's what you must do to get your pressure back.
My advice? Get three estimates and go with 5the one you're most comfortable with. Good luck. Tom

Thank you! That makes allot of since.
