When it comes to home maintenance, water pressure probably isn’t the first thing that comes to mind—but it should be. Whether too high or too low, improper water pressure can silently damage your plumbing system and significantly reduce the lifespan of expensive appliances like dishwashers, washing machines, and water heaters. If you're noticing appliance issues or pressure fluctuations, it might be time to speak with a professional. For expert diagnosis and solutions in your area, reach out to a trusted Plombier Rive-Sud to make sure your water pressure is right where it should be.

What Is Water Pressure—and Why Does It Matter?

Water pressure refers to the force at which water enters your home’s plumbing system from the main line. It’s measured in pounds per square inch (PSI), and the ideal residential water pressure typically falls between 40–60 PSI.

Water pressure that’s too high or too low can put unnecessary stress on your plumbing fixtures and appliances, leading to more frequent breakdowns and early replacements.

How High Water Pressure Damages Appliances

Excessively high water pressure (above 70 PSI) can cause:

• Seal and gasket failures in washing machines and dishwashers
• Premature wear on internal components like valves and hoses
• Frequent leaks in appliances and pipe connections
• Shorter lifespan for water heaters and other high-usage devices

Over time, this pressure can cause small cracks or slow leaks inside appliances that go unnoticed until major damage occurs.

Low Water Pressure Isn’t Safe Either

On the flip side, low water pressure can lead to:

• Incomplete rinse cycles in dishwashers
• Inefficient washing machines
• Poor water flow to water heaters, reducing their performance
• Potential buildup of sediment due to sluggish water movement

Appliances aren’t designed to work under constant strain, and if the pressure is too low, they have to work harder—wearing them out faster.

Appliances Most Affected by Water Pressure

🔧 Dishwasher – Can suffer from leaky seals, inefficient cleaning cycles, and short lifespan due to either extreme.
🔧 Washing Machine – High pressure can burst hoses, while low pressure leads to longer, less effective cycles.
🔧 Water Heater – High pressure increases the risk of leaks and reduces the unit’s efficiency over time.
🔧 Refrigerator with Water/Ice Dispenser – Pressure issues can damage the water inlet valve or reduce ice-making performance.

How to Know If Your Water Pressure Is Too High or Low

Watch for these signs:

• Loud banging pipes (also called water hammer)
• Leaking appliances or hoses
• Slow or weak water flow
• Shortened appliance lifespan or frequent repairs
• Sudden spikes in your water bill

You can also use a water pressure gauge to test PSI at a hose bib or faucet. Or better yet, let a professional test it for you and diagnose potential risks.

Protecting Your Appliances (and Your Wallet)

Here’s how to maintain healthy water pressure and protect your investment:

• Install a pressure-reducing valve (PRV) if your pressure is consistently too high
• Schedule annual plumbing inspections to monitor pressure and appliance condition
• Use stainless steel braided hoses for washing machines and dishwashers
• Flush your water heater regularly to prevent sediment buildup, especially in areas with low pressure
