Understanding Water Pressure and Why It Matters

Water pressure is measured in pounds per square inch (PSI). Ideally, your home’s water pressure should be in the 50–60 PSI range. Anything consistently over 80 PSI is considered too high and puts your pipes and appliances at risk. On the flip side, low water pressure makes it difficult to shower, wash dishes, or use your laundry efficiently. If you're noticing slow water flow or bursts of forceful water, it’s time to call in a licensed plumber who knows how to get things flowing properly—the SMART way.

SMART Solutions for High or Low Water Pressure

At SMART Plumbing LLC, we use a thoughtful and calculated approach to identify the root cause of your pressure issues. In many cases, the solution lies in installing or servicing a Pressure Reducing Valve (PRV)—a device designed to regulate and stabilize incoming water pressure, keeping it within safe and usable limits throughout your home. A PRV can be set to your desired pressure, and once installed, it automatically adjusts to fluctuations in supply pressure or water demand. It’s an efficient way to protect your pipes, fixtures, and appliances—without you ever needing to think about it again.

Common Dangers of High Water Pressure

Excessive water pressure can cause more than just annoying noise. It can lead to system-wide damage, wasted water, and even dangerous situations. Here are some of the typical issues associated with high pressure:

Water hammering – Loud banging or knocking sounds in your pipes caused by pressure surges

Pipe stress and bursting – Continuous high PSI can weaken joints and seals, leading to water damage

Water heater failure  – Thermal expansion increases internal pressure, potentially causing the tank to crack or rupture

Leaky fixtures – Faucets, hose bibs, and showerheads can begin dripping under constant pressure

Increased water bills – More pressure means more flow and more water use

Shorter appliance lifespan – Washing machines, dishwashers, and ice makers can wear out faster under strain
