Water Pressure: What to Know & How to Measure It

Today we’re going to talk about why it’s important to know your water pressure. You’re probably already a little familiar with water pressure, and how it affects your daily life. But did you know your water pressure also impacts virtually every aspect of your home’s plumbing system?

For most people, water pressure concerns don’t extend past turning the shower on when they get up in the morning. Many prefer their water pressure when they take a shower to be a little higher, though some like it on the lower end, too. Yet the truth is extreme water pressure on both sides of the spectrum is something to be wary of.

More and more plumbing components today are made from plastic. In your toilet especially, while you may assume that everything is porcelain, chances are a lot of the parts are actually manufactured from a plastic hybrid. When your water pressure is too high, it tends to wear less sturdy components and materials like this down faster. High water pressure can also lead to burst pipes, which is something no homeowner wants to deal with. Conversely, low water pressure, to the point where your sinks and drains run extremely slow, can be just as bad. On top of being frustrating, low water pressure may also be a sign that there is corrosion or sediment in your piping, which in turn can cause leaks.

So, what s a healthy rate for water pressure? The inlet water pressure of the average American home is 40 to 45 psi (pounds per square inch.) Your pressure regulator specifically is usually set at 50 psi. Generally, it is possible to adjust the water pressure in your house anywhere between 25-75 psi, however, water pressure in most homes should not exceed 60 psi.

Measuring Your Water Pressure

Measuring your water pressure does not have to be a difficult task. Moreover, it is something every homeowner should be able to do to help keep their plumbing equipment in good condition.

You can measure your water pressure right now by:

  1. Turning off running water in your house;
  2. Locating your main water supply pipe;
  3. Attaching a pressure gauge at the spigot running off the main water supply (if you do not have a pressure gauge, you can buy one easily at most home renovation and hardware stores, or order one online);
  4. Turning the valve next to the spigot counterclockwise;
  5. Recording the psi level of the water as it runs through the gauge.

It’s important to remember to unscrew the pressure gauge and turn your spigot off after this process has finished. If you do not have a pressure gauge and are looking for a less accurate but cheaper way to measure your home’s psi, you can also place a bucket by the the spigot in the first floor or basement of your house, turn it on, and time how long it takes that bucket to fill up with a gallon of water. Once the bucket is full, you can divide the total amount of seconds it took for the water level to reach a gallon by 60. This should give you’re an approximate measurement of your water pressure.
