YouWhy Is My Water Pressure So Low? 6 Possible Causes in Your Kansas City Home
You turn on the shower and barely get enough pressure to rinse off. The kitchen faucet isn’t flowing like it used to. Or maybe the water pressure drops every time someone starts the washing machine.
If you’re dealing with low water pressure in Kansas City, it can be more than just an annoyance. Sometimes the cause is relatively simple. Other times, a noticeable change in water pressure can be a sign of a plumbing problem that deserves attention.
Here are six possible reasons your home’s water pressure isn’t what it used to be.
1. The Problem Could Be the Fixture
Before assuming there’s a problem with your entire plumbing system, check whether the low pressure is happening in one location or throughout the house.
If only one faucet or showerhead is affected, the fixture itself could be the problem.
Mineral deposits and debris can build up in faucet aerators and showerheads, restricting water flow. Cleaning or replacing the affected component may improve the situation.
If multiple fixtures have suddenly lost pressure, however, it’s worth looking deeper.
2. A Partially Closed Valve Could Restrict Water Flow
Your home’s plumbing system has valves that control water flow. If a main shutoff valve isn’t completely open, it may restrict the amount of water moving through your pipes.
This can sometimes happen after plumbing work has been performed and a valve wasn’t fully reopened.
If you’re not sure where your shutoff valves are or whether they’re operating correctly, a plumber can inspect the system.
3. You Could Have a Hidden Leak
A plumbing leak doesn’t always leave a puddle where you can see it.
Water escaping somewhere in the system can potentially contribute to changes in pressure. Other clues could include an unexplained increase in your water bill, damp areas, water stains, or the sound of running water when everything is turned off.
If your pressure suddenly drops without an obvious explanation, don’t ignore it.
4. Your Pressure Regulator May Be Having Problems
Some homes have a pressure-reducing valve, commonly called a pressure regulator, that helps control the pressure of water entering the house.
If that component isn’t operating correctly, you may notice water pressure that’s too low, too high, or inconsistent.
Diagnosing a regulator problem isn’t something you need to guess at. A plumber can test the home’s water pressure and determine whether the regulator is working correctly.
5. Older Plumbing Can Affect Water Flow
Older homes can sometimes have plumbing that has deteriorated or accumulated buildup over many years.
Corrosion and mineral buildup inside certain types of older pipes can gradually reduce the available space for water to flow. Unlike a clogged showerhead, this isn’t necessarily a problem you’ll be able to see from the outside.
If your home’s water pressure has gradually become worse over the years, the plumbing itself may be worth evaluating.
6. The Problem Might Not Be Inside Your House
Not every water pressure problem originates in your home’s plumbing.
Work on municipal water lines, neighborhood water issues, or other problems outside your property can sometimes affect water pressure. If the change happened suddenly, it can be helpful to find out whether nearby homes are experiencing the same thing.
If everyone else has normal pressure and yours has dropped, the problem is more likely specific to your property.
How Much Water Pressure Should a Home Have?
Water pressure shouldn’t be a guessing game.
Pressure that’s too low can make showers, faucets, appliances, and everyday tasks frustrating. Excessively high water pressure isn’t necessarily better, either, because it can put unnecessary stress on plumbing fixtures and components.
A plumber can measure your home’s water pressure and use that information to help narrow down the cause of the problem.
