First, understand the job.

Guessing at water pressure is like guessing at tire pressure. A simple hose-bib gauge gives you a useful number.

Step by step

Do it in this order.

1

Make it safe

Attach a pressure gauge to an exterior hose bib or laundry connection.

2

Find the actual problem

Measure static pressure with all fixtures off.

3

Make the repair

Measure again while a fixture runs to expose flow restrictions.

4

Test your work

Inspect the pressure regulator, main valve, and supply piping before blaming individual faucets.

One last check

Dry everything, run the fixture more than once, and look again in ten minutes. A tiny drip now becomes cabinet damage later.
