Water pressure is one of those things we often take for granted—until it becomes a problem. Many homeowners assume that higher pressure means better showers, faster dishwashing, and quicker filling sinks. But when it comes to plumbing, more isn’t always better. In fact, excessive water pressure can quietly damage your pipes, fixtures, and appliances over time, leading to costly repairs and premature replacements.
What Is Considered Excessive Water Pressure?
In most homes, water pressure should fall between 40 to 60 psi (pounds per square inch). Anything consistently above 80 psi is considered too high and can strain your plumbing system. You might not notice the signs right away, but over time, the consequences can be significant.
Signs Your Water Pressure Might Be Too High
Banging or noisy pipes (also called “water hammer”)
Leaking faucets or constantly dripping spouts
Toilet issues, such as constant running or phantom flushing
Premature failure of water-using appliances like dishwashers and washing machines
Increased water bills, despite no change in usage
Why High Water Pressure Is a Problem
Think of your plumbing like your car’s engine—it’s designed to operate within a certain range. Excessive water pressure forces your pipes and appliances to work harder than they should, which can cause:
Pipe damage: The constant stress can lead to cracks or leaks in your plumbing system.
Fixture wear and tear: Faucets, valves, and seals can wear out faster under high pressure.
Water heater damage: High pressure can stress your water heater, increasing the risk of leaks or system failure.
Wasted water: Higher pressure means more water usage, even if you don’t realize it. This is bad for both your wallet and the environment.
What to Do About It
If you suspect your water pressure is too high, don’t ignore it. Here’s what you can do:
Test the water pressure – You can buy an inexpensive pressure gauge at most hardware stores. Simply screw it onto an outdoor spigot and turn the water on to get a reading.
Install a pressure-reducing valve (PRV) – If your pressure is consistently too high, a licensed plumber can install a PRV on your main water line to regulate and maintain a safe pressure level.
Schedule a plumbing inspection – A professional can assess your system, identify any damage caused by excessive pressure, and recommend long-term solutions.
Maintain your system – If you already have a PRV, it should be checked periodically to ensure it’s working properly.
Final Thoughts
High water pressure might seem like a luxury, but it’s a silent threat to your plumbing system. Catching it early can save you from major headaches down the line. Regular maintenance and a simple pressure check can go a long way toward preserving the health of your home’s plumbing.
