Low Water Pressure


All residential properties obtain water through pipes from either the municipal water supply department or water wells. The kind of water pressure you experience in your household depends upon your source of water, your location, and the condition of pipes and faucets.

If your house is situated at a level that is lower than that of the municipal water supply, for instance, you may experience high water pressure. Homes and structures situated at higher points, on the other hand, often experience low water pressure. There’s no need to worry, though. You can usually control water pressure by  making a few minor plumbing changes. It’s a good idea to read up on what these changes entail before attempting to make them, so let’s take a look at what water pressure actually is and how to cope with water pressure that’s too high or too low.

Water Pressure: What is it and how is it measured?

Water pressure is simply the force that enables water to flow through pipes and into our homes. Without this pressure, it would be impossible for water to reach the taps. Although the recommended water pressure for homes is usually 80 psi, most people find that they’re water pressure is too high or low. High water pressure can range from somewhere between 100 to 150 psi while anything lower than 80 psi would be considered low water pressure.

If you are experiencing too many leaks or cracks in your pipelines or the water is not flowing adequately through your tap, you may have problems with water pressure. You can measure the pressure in your pipes by using pressure-measuring gauze that is screwed onto the hose. The needle on the gauze will determine the level of pressure.

High Water Pressure: Causes and Solutions

One of the most common causes of high water pressure is excessive levels of pressure coming from the municipal water supply. The municipal water supply may increase its pressure in order to fulfill the water requirements of buildings, homes, and structures that are tall or located in far away areas. The pressure also tends to run higher at night than during the day.

Thermal expansion is another potential cause of increased water pressure. When water is heated inside your home, for instance, it increases the water pressure in the pipes. Excessive water pressure is problematic and may involve expensive repairs if left untreated. It can cause leaky faucets, running toilets, banging pipes, and even cracks in the pipeline, all of which have the potential to be quite damaging.

The problem can be addressed easily by installing a pressure regulator in the main line. It will considerably reduce the pressure coming from municipal supply to a safer range and help in minimizing the faults. If you already have a pressure regulator installed and are still experiencing high pressure, you may need to check the functionality of the valve as such valves tend to get damaged easily. Replacing the regulator may solve your problem.

Low Water Pressure: Causes and Solutions

Low water pressure can occur when your house is situated significantly above the level of your water source. Low water pressure can be severe enough to completely halt your water supply, but installing a pressure booster pump will solve this issue.

Clogged water line or faucets are another potential cause as they often slow down water pressure. Corroded pipes in old homes may also cause the water to flow slowly. Consider cleaning or replacing old pipes and faucets.

Lastly, if your house has a pressure regulator near the main supply line, check for its functionality. A regulator that is malfunctioning or broken can cause a drop in water pressure. Resetting or replacing the pressure regulator may result in a considerable increase in water pressure.

Experiencing water pressure that is inadequate or excessive is a common problem that you can address yourself if you have adequate knowledge of plumbing. That said, it is best to hire a professional plumber if you have trouble discerning the exact cause of your water pressure issues.
