Why Is My Water Pressure So Low?

Many people wonder what is happening with their water systems at home when water pressure runs low. This article is for you if you have had similar concerns.

We will discuss the causes of low water pressure and the possible solutions to get you sorted. Let us dive in.

Why Your Water Pressure Is So Low

Low water pressure can be a result of many things. Simple reasons include problems with your shutoff valve closed or a blocked faucet. More serious causes of low water pressure could be plumbing blockages and water leaks.

Troubleshooting Low Water Pressure at Home

Once you have identified the low water pressure causes, next is to make sure you know how to troubleshoot such issues. Here are some steps to help you troubleshoot your home low water pressure:

  • Determine all locations within your house or office with low water pressure.
  • Next up straight after you have identified low water pressure and its cause at home, check all areas with faucets.
  • Check individual faucets to see if low water pressure is in any specific location.

The low water pressure problem may only affect one or a few locations in your house. In this case, the source of low pressure is likely a clogged faucet or sometimes an aerator. To troubleshoot a single site or two with low water pressure, you will need to do the following:

  • Remove the end of your faucet.
  • Examine your aerator thoroughly – check the aerator to make sure there are no buildups and debris.
  • If your aerator has debris and buildup, soak it in water mixed with vinegar to clean it.

Once you are done with the above processes, turn on the water and check its pressure. If water is not restored to normal pressure, the problem is not with an individual faucet but with your entire home water system.

When it comes to low water pressure problems, another problem is the lack of using a PRV – Pressure regulating valve. Here is how a pressure regulating valve works to help you prevent low water pressure at home:

Often called a pressure regulator, a PRV valve uses spring pressures against a diaphragm design to open faucets valves. In cases of water pressure dropping below Faucets set points, the valve spring pressure overcomes the outlet pressure. This forces the valve to stem downwards, thus opening the valve allowing water to flow with high pressure.

How to Increase Water Pressure at Your Home?

If you have a PRV and you have checked all the faucets at home with all locations identified, you need a guide on how to increase your water pressure and here is how:

  1. Make sure your home shutoff valves that are located near the water meter are fully open.
  2. After you have opened all the shutoff valves, reaccess the pressure before deciding on doing something else to handle the issue.

Why is my water pressure so lowIf opening shutoff valves is not an option for you, try testing your water pressure with a pressure gauge that you can easily purchase from home centers. To check water pressure with a pressure gauge, here is the process:

  1. Hook your gauge to an outside water spigot and then turn the water on. The gauge will give you instant readings; use these readings to determine the problem.
  2. If your pressure gauge gives you low readings, the problem is not with your water system, but your city water regulating center is delivering water at moderate pressure to all households in your area.

Use A Pressure Booster

Installing a pressure booster is an excellent way to increase the water pressure at home. A pressure booster works by utilizing pressure using an electric pump and a pressure tank. To improve water pressure, you will only have to dial adjustments settings within the booster, and you will have water flowing with high pressure.

Welcome back, Coachella Valley. Rick Cubas here, owner of Preferred Air Conditioning Heating and Plumbing, coming to you live with another segment of Preferred Pointers.

Rick Cubas:
In today’s segment, I want to talk to you about a question we get quite frequently from our homeowners, and that is, “Rick, why do I have such low water pressure?” Now, there could be many reasons why that’s happening, but one of the main things that we find out here is, our customers don’t have what’s called a pressure regulating valve, or also known as a PRV.

This is what it looks like and it’s typically connected to the hose bib, or your main water going into your home, typically around your gas meter area, somewhere on the exterior of your home. But the PRV actually regulates the water pressure going into your house so you can adjust it higher or lower with this adjusting nut right here.

Rick Cubas:
And you want to make sure that that water pressure is appropriate because you also don’t want the water pressure too high. Now I know we love to fill up our tubs quickly, we love the amount of water that comes out of our showers when it’s coming out hot and fast, but our plumbing systems were only meant to typically have anywhere from 45 to 55 PSI, pounds per square inch.

And when you get over that, that’s when you start springing leaks and having problems at the connections. So we’d love to talk to you more about the PRV, the pressure regulating valve. You want to make sure that you have one installed.
