Common Low Water Pressure Causes and Cures

Water Pressure ValveLow water pressure in the house can be irritating, especially when trying to take a shower or wash your dishes. Although most people take the blame to the municipal water supply, several other factors can be the leading cause of low water pressure in your home. If you have been noticing a drop in water pressure for a couple of days, then chances are there is something wrong with the plumbing system. Diagnosing and inspecting everything from the water inlet from the main line to the house’s piping system can help identify and correct the problem in no time. You can choose to do this yourself to identify the problem, or call a certified plumber to inspect the system. Outlined below are some of the most common low water pressure causes cures in the house.

Four Common Low Water Pressure Causes Cures

  1. Debris buildup in pipes: Inlet pipes are susceptible to debris accumulation even without a broken or leaking line. Most of this debris is composed of dirt, pollutant and sand from the water source. These sediments are pumped right into your home’s piping system over time. The debris builds up with time creating a blockage in the pumping system causing a drop in water pressure. Such debris mainly builds up in the main water inlet and into the taps. To correct the problem, close the water inlet valve then unscrew it to remove any debris in the same. Consider placing a screen in the valve to filter out most of this debris from finding a way into your piping system.
  2. Mineral buildup: Mineral sediments build up over time to create a major clog in the piping system. Although it would take at least 5 years for the mineral buildup to have an impact on your house’s water pressure, this shouldn’t be ruled out either. Nonetheless, getting rid of such as clog as pretty simple, as all you will need are plumbing chemicals to flush and break down the minerals. You can inquire this from a plumber or plumbing supplier.
  3. Piping corrosion buildup: Most homeowners prefer having galvanized or steel water pipes installed in their homes. Although these piping systems can last up to 20 years without causing any problem, they are highly vulnerable to natural corrosion. The corrosion is mainly caused by water under high pressure as well as water purification solutions used in the same. Repairing galvanized piping systems is however a tricky exercise, which is the reason why the only, and best, viable option is to replace all the pipes. Replacing all the pipes helps take care of the corrosion and restore normal water pressure.
  4. Leaks in the plumbing system: A slow leakage in the main plumbing system can result in a significant drop in water pressure. This is one of the leading common low water pressure causes cures for most homeowners. The leaking point leads to loss of pressure thus causing a drop in the same in all water points around the house. Nonetheless, inspecting the entire plumbing system should help you identify the leaking point that needs to be repaired.

Diagnosing a water leakage (especially slow leakage) can however be a daunting and time-consuming task. The best way to do this is by taking the meter reading in the morning and the evening. If the reading has changed, that’s a definite indicator of a leakage. The best way to deal with water leakage is by calling a certified plumber to handle the repairs.

If none of the above-mentioned factors is causing low water pressure, then the problem could be with the municipal water supply. Calling the municipality about the same should however help rectify the problem. The municipality has a designated team that inspects and repairs any leaking points to restore water pressure to consumers.
