Low water pressure is a common plumbing problem that can affect your home, especially if you have a well water system. Since well systems use pumps to move water up into a tank that then provides to your home, there are more places where water pressure issues can arise when compared to municipal water mains. Understanding some of the reasons why your well water pressure is low can help you identify and fix issues as soon as they arise.
One of the simplest reasons why your water pressure may be lower on a well system is if you have multiple taps or appliances drawing water at the same time. Well pumps have a more limited capacity when compared to traditional water main hookups, which can make maintaining the same level of water pressure difficult. In the short term, you should only run a few taps or appliances at a time to ensure proper water pressure. In the long run however, you may want to consider installing a larger and more powerful pump to properly service your entire home.
Damaged Water Pump
In most cases, a reduction in your well's water pressure is directly attributable to the performance of your well pump. A damaged or old and worn out well pump will no longer be able to provide the same stream of water that you are used to. Determining if your well pump is damaged can be difficult, but some of the more common warning signs include higher utility bills caused by an ineffective pump running for longer to provide water to your home, dirt and other contaminants within the water supply, and the pump turning on and off at seemingly random periods during the day when no tap or water using appliance is running.
Finally, the most serious issue that could be affecting the water pressure in your well is a problem with the aquifer. A lack of rainfall, constant use and other environmental factors can cause your well's water level to drop significantly, which means that your pump is struggling to actually move water into your home. While sometimes these environmental factors are temporary, and a period of rainfall can restore your home's water pressure, other times they are more serious. In this case, you may have to dig an entirely new well on your property to reach enough water to adequately provide for your home.
