Plumbing issue.... low flow....

Any of you good with plumbing diagnostics?
I've never been satisfied with the water flow rate in my house and I finally got off my ass to work on it.
The pressure at the outside bib is 75psi so I'm on the high side of good but still good. With gauge still attached I opened up the kitchen faucet and the pressure dropped to 42. That's a huge drop. I've read to expect a 5-10 psi drop so I wasn't expecting 30+! After letting things sit a bit the gauge read 53psi and is holding steady.

Some details.....

House is only 25 years old and all plumbing is copper.
It's a small house so there really isn't a lot of plumbing at all.

The lack of flow is at all outlets, even the garden hose.

Any thoughts?

 

PSI is analogous to Volts. Gallons per minute is analogous to Amps. Your pipe size is Resistance. To increase flow you need to decrease resistance. That is increase pipe size (larger gauge wire), and or reduce restrictions in your plumbing.

 

what size of pipe is coming in and what size is going to your house?

 

A lot of homes have water pressure valves where the source comes into the home. It's possible the valve has failed, I had a friend who's valve was even installed backwards and was causing his water pressure to be extremely low

 

We deal with too much water pressure in my area. At our previous house, we had a pressure reducer valve. Looks like a bell. Ours was connected near our meter and shut-off valve. I figured that might be worth mentioning.

Also not sure if you're connected to city water. If so, it's possible there could be something going on with that connection (the street to your house). They'll come check that for free. At least they do where I live.

 

At 25 years you may also have corrosion build up in the copper supply pipes that can restrict flow and reduce pressure.
