Three Common Reasons For Low Water Pressure

Posted on

The water pressure of your plumbing system is an extremely important, if often overlooked, factor in its efficiency. Low water pressure makes it much harder for you to take a shower or wash dishes and can also negatively affect the performance of water using appliances like your laundry machine. There are a variety of different reasons why your home may be suffering from low water pressure, each with different solutions. Understanding what some of the most common reasons are and how to troubleshoot them can help you get your plumbing back to normal again.


One of the most common reasons for low water pressure in your home is corrosion in the pipes, especially if you have noticed that the water pressure has gradually gotten lower over time. Corroded pipes can collect sediment within them, which reduces the amount of water that is able to flow through them and thus causes low water pressure. In severe cases, leaks can develop, which will also reduce water pressure in your home. You can tell if you have corroded pipes in your house if you notice that there are red or orange flakes within your water supply.

Hard Water

A similar reason for low water pressure to the above point is if you have hard water. Hard water refers to water with dissolved calcium and other minerals in it, which will slowly form a white chalky buildup over time within your pipes and on your water fixtures. Fortunately, you can fix your hard water problem simply by installing a water softener, which will filter these minerals out of your water supply at the source – the water main. Get in touch with a plumber if you notice any sort of chalky buildup on your water fixtures.


As mentioned already, leaks can cause the water pressure in your home to suddenly and seemingly inexplicably drop. Leaks will cause water damage somewhere in your home, so be on the lookout for the sound of running water even when all taps are off, any sort of stains and discoloration on your walls or ceiling and a musty and earthy odor that can point to mold and mildew growth in the affected area. When you find the area where a leak is occurring, you should turn the water supply off – usually located in the basement of your home – and get in touch with an emergency plumber to complete the water pressure repair.
