How to Test Water Pressure
When it comes to water pressure, there’s a fine line to too high and too low. You need your water pressure to be a sufficient pounds per square inch (psi) of water in order to fill appliances, water your garden, and perform other tasks with minimal frustration. However, if your water pressure is too high, it will stress your pipes, appliances, and fixtures. That’s why it’s good to test water pressure from time to time, especially if you see signs that it’s too high or too low.
How to Test Water Pressure
Testing your water pressure is relatively easy and inexpensive; you can totally do it yourself at home. Get a pressure gauge from Amazon or your local hardware store and simply hook it up to a hose faucet. This should cost you between $10-15. Turn off all faucets and appliances and check the pressure to record your baseline water pressure. If it registers between 30 and 80 psi, your water pressure is just fine.
If you don’t want to get a pressure gauge and just want to do a quick test, try this: turn on both the shower and sink faucets in your master bathroom and flush the toilet. If the shower water flow drops while the toilet is filling, you’ve got water pressure problems.
Low Water Pressure
Maybe your shower flow diminishes to a trickle when other people are using water in the house(or appliances are running). Perhaps your washing machine seems to take forever to fill. You might hear a whistling sound coming from the pipes. All of these are signs that you have low water pressure.
But What Causes Low Water Pressure?
The following are common causes of low water pressure.
A Hidden Leak
One of the most common causes of low water pressure is a hidden leak. If this is the case, be happy you have discovered it – the longer a leak goes undetected, the most damage is possible (and the more money you’ll waste on water bills). Check your water meter (click here to learn how), and if you decide the problem is probably a leak, have a plumber out who uses leak detection equipment (click here to learn about our techniques and equipment).
Mineral Deposits in Pipes
Your pipes are supposed to remain click and smooth on the inside, but you may have problems with mineral deposits or corrosion, especially if you have hard water or water from a source that has a lot of minerals in it. This can also happen if your pipes are very old and are corroding. If there has recently been a break in the local municipal system, there may be debris in your pipes. You’ll probably see rusty colored water if this is the case.
Your Local Municipal is Having Problems
Once in a while we encounter a situation where the problem is actually the local municipality due to a break in a water main nearby. Call your local water department and ask if they are having problems of this nature.
High Water Pressure
Is water blasting out of your faucets? Have you heard the classic banging sound from the pipes (also known as a water hammer) when water is running? Is the pressure irregular — sometimes really intense and sometimes regular? it might feel fantastic in the shower, but you’re worried about the impact on your water bill. Worse yet, high water pressure can destroy the fixtures, especially those connecting your appliances to water sources, resulting in leaks and wearing down appliances, making them break down sooner.
What Causes High Water Pressure?
Believe it or not, your home’s location is probably the cause. If you live at the bottom of a hill, gravity may cause high water pressure. If you live near or in skyscrapers or fire hydrants, you might have high water pressure because the local water company keeps the pressure high near tall buildings or hydrants. It’s also possible that your water heater is causing thermal expansion inside your home, causing changes in water pressure.
How High is Too High and What Can You Do About It?
If your water pressure goes over 80 psi (even occasionally), you should install a pressure regulator to your water main line. This will protect your plumbing and appliances, saving you money both on water bills and appliances and long term plumbing.
