Understanding Your Home's Water Pressure: Causes for Concern

In the heart of every home, plumbing is a critical system that many homeowners often overlook. It is only when a plumbing issue such as low water pressure emerges that we realize the implications of having an efficient home plumbing system. At Columbia Plumbing, we understand these challenges and are committed to helping homeowners identify and address common plumbing problems for a seamless living experience.

Understanding Water Pressure

A home's water pressure is the force generated by water to move from the municipal supply or well into your faucets. Healthy water pressure is not only convenient for everyday tasks but also crucial in maintaining the overall health of the plumbing system. As a rule of thumb, residential water pressure should lie between 40-70 pounds per square inch (psi). A psi of 80 or above could damage appliances and fixtures, while anything below 40 psi would result in inadequate water flow.

Causes of Variation in Water Pressure

There are several reasons why your home could be experiencing fluctuations in water pressure. One of the most common causes is old and corroded piping systems. Over time, pipes may accumulate deposits, leading to blockages which limit water flow. In some cases, the pressure may be lowered intentionally during maintenance or in response to a local drought.

A faulty pressure regulator can also lead to changes in water pressure. This valve adjusts the pressure from the municipal supply to a level that's suitable for home use. If it fails, the pressure could increase dramatically, causing potential hiccups to your plumbing system.

Lastly, a leak in the system could result in water pressure issues. They not only waste water but also reduce the flow rate to your faucets and fixtures. Plumbing leaks require immediate attention as they can lead to more severe problems down the line — something we, at Columbia Plumbing, can assist you with.

Identifying Low Water Pressure

Identifying low water pressure is simple. If your faucets or showers take longer to fill containers or the water flow is noticeably weaker, you're likely dealing with an issue of low water pressure. In some cases, an abnormal or high water bill may also point towards a leak, which in turn can affect water pressure.

Actions to Take

Once you’ve identified low water pressure in your home, it's essential to avoid any DIY fixes and instead call a professional immediately.
