Water pressure might not be something you think about daily, but it plays a pivotal role in our daily routines. From taking a refreshing shower to washing dishes, the right water pressure ensures tasks are done efficiently. But what happens when the pressure is too high or too low? Understanding and managing your home’s water pressure can save you from potential plumbing issues and enhance your overall water usage experience.

1. What is Water Pressure?

Water pressure refers to the force exerted by water as it moves through your home’s pipes. It’s typically measured in pounds per square inch (PSI). The ideal water pressure for most homes ranges between 50 to 70 PSI.


2. Signs of Water Pressure Issues

  • Low Pressure: Water trickles from taps, showers lack force, and appliances like washing machines take longer to fill.
  • High Pressure: Water blasts out when taps are turned on, frequent pipe leaks, and noisy or vibrating pipes.


3. Causes of Low Water Pressure

  • Pipe Leaks: Water escaping from leaks reduces the overall pressure.
  • Corroded Pipes: Over time, old iron pipes can corrode, restricting water flow.
  • Clogged Pipes: Mineral deposits or debris can reduce water flow.
  • Faulty Fixtures: Sometimes, the issue is with a specific faucet or showerhead.
  • Valve Issues: Ensure the main shut-off valve is fully open.


4. Causes of High Water Pressure

  • Elevation: Homes at the bottom of a hill can experience higher pressure due to gravity.
  • Thermal Expansion: When water heats up in a water heater, it expands, increasing pressure.
  • Municipal Supply: Sometimes, the city supply is set at a high pressure to cater to large buildings or fire hydrants.


5. How to Check Your Water Pressure

  • Pressure Gauge: Attach a pressure gauge to an outside water spigot and turn on the water. The gauge will give a PSI reading.
  • Professional Check: If you’re unsure, consider getting a professional like CID Plumbing to assess your home’s water pressure.


6. Adjusting Your Water Pressure

  • Pressure Reducing Valve (PRV): If your pressure is consistently high, consider installing a PRV to reduce it.
  • Clean Faucets and Showerheads: Mineral buildup can restrict flow. Regularly clean or replace fixtures.
  • Fix Leaks: Addressing leaks can often restore pressure.
  • Expand Pipe Size: For homes with consistently low pressure, consider upgrading to larger pipes.


7. The Risks of Ignoring Water Pressure Issues

  • Pipe Damage: High pressure can lead to leaks or bursts.
  • Appliance Wear: Appliances like dishwashers and washing machines can wear out faster.
  • Wasted Water: Leaks from high pressure can lead to significant water wastage.



Maintaining the right water pressure is essential for the longevity of your home’s plumbing system and your comfort. Whether you’re facing issues of high or low pressure, understanding the causes and solutions can save you time, money, and potential headaches. And remember, while DIY solutions can address minor issues, don’t hesitate to call in experts like CID Plumbing for comprehensive checks and solutions.
