Why High Water Pressure Isn’t Always Better for Your Home

Strong water flow can feel like a benefit, especially when multiple fixtures are in use. However, when it comes to residential plumbing, higher water pressure is not always better. Excessive pressure is a common but often overlooked factor that can shorten the life of plumbing systems and household appliances.

Understanding how water pressure works and how it is controlled helps homeowners make informed decisions that protect their plumbing investment over time.

What Is the Ideal Water Pressure for a Home?

Most homes operate best with water pressure between 50 and 70 PSI (pounds per square inch). This range provides reliable flow while staying within the limits recommended by plumbing codes and appliance manufacturers.

City water pressure is frequently much higher than what a home actually needs. Municipal systems must deliver water across large areas, varying elevations, and multiple buildings, which often requires higher pressure. Without proper regulation, that pressure flows directly into a home's plumbing system.

How Excessive Water Pressure Affects Plumbing Systems

When water pressure remains above recommended levels, it places added stress on all components of the plumbing system, including:

• Pipes and fittings

• Faucets and shutoff valves

• Toilets and shower components

• Water heaters

• Appliances such as washing machines and dishwashers

Over time, this constant stress increases the likelihood of leaks, fixture failures, and reduced appliance lifespan. These issues often develop gradually, which is why high water pressure can go unnoticed until damage occurs. Proper water pressure control benefits homes of all ages and construction types.

What Is a Pressure Reducing Valve (PRV)?

A Pressure Reducing Valve (PRV) is a mechanical valve installed on the main water line where it enters the home, typically just after the main shutoff valve. Its purpose is to reduce incoming city water pressure to a safe level for residential plumbing.

How a PRV Works

A PRV automatically lowers high incoming water pressure and maintains a consistent, preset pressure throughout the home. Once adjusted by a plumber, it continues regulating pressure even when city water pressure fluctuates during the day.

PRVs are adjustable and designed to keep household pressure within a stable range, most often between 50 and 70 PSI, helping protect plumbing components and appliances from unnecessary strain.

PRV Lifespan and Signs of Wear

Most Pressure Reducing Valves last approximately 8 to 15 years, depending on water quality, usage, and local conditions.

Common signs that a PRV may be wearing out or failing include:

• Water pressure readings that gradually rise above normal levels, sometimes exceeding 80 PSI

• Pressure that fluctuates noticeably throughout the day

• Banging or knocking noises in pipes

• Reduced or inconsistent water flow at fixtures

Because these changes often happen slowly, routine pressure checks are an important part of preventative maintenance.

Why Testing Your Water Pressure Matters

Periodically testing your home's water pressure helps identify potential issues before they lead to leaks or equipment damage. Many homeowners check pressure at an exterior hose bib for a quick snapshot, while professional evaluations provide more precise readings and confirm whether the PRV is operating correctly. Maintaining proper water pressure supports long-term plumbing reliability, fewer repairs, and longer-lasting appliances.

Professional Support for Water Pressure Control

If your home does not have a Pressure Reducing Valve, or if an existing PRV is no longer regulating water pressure correctly, a licensed plumber can evaluate your system and recommend the appropriate solution. Proper installation and adjustment are essential for consistent performance and long-term protection.
