"Fast, professional service! My kitchen faucet was fixed in no time."

Sarah M., Naperville, IL

Why is my water pressure suddenly low all over the house?

Is your shower weak and unsatisfying? Do your pipes bang and shudder when a toilet flushes? These are more than just annoyances; they are symptoms of a water pressure problem that could be silently damaging your plumbing and appliances. At Principle Plumbing, we provide comprehensive water pressure diagnostics to pinpoint the exact cause and offer lasting solutions.

Principle Plumbing water pressure diagnostic testing

What causes a sudden drop in water pressure throughout my whole house? A sudden, house-wide pressure drop often indicates a major issue. The most common causes are a failed Pressure Reducing Valve (PRV), a partially closed water meter valve, or a significant, undiscovered leak in your main service line. Our lincensed, bonded, insured plumbers use professional-grade gauges to test your system and identify the exact cause, saving you from expensive guesswork.

How can I check my own water pressure? You can buy a simple water pressure gauge from a hardware store for about $15. Screw it onto an outdoor hose bib, turn the water on all the way, and read the PSI. In DuPage County and Chicaland, ideal residential water pressure is between 45 and 65 PSI. If it's above 70 or below 45, it's best to call Principle Plumbing for a professional diagnostic to find the root cause.

Could old pipes be causing my low water pressure? Absolutely. Older DuPage County and Chicaland homes may still have galvanized steel pipes. Over decades, these pipes corrode and fill with mineral scale from hard water, restricting water flow like a clogged artery. We assess your plumbing system to determine if pipe constriction is the culprit. In these cases, replacing old pipes with modern copper or PEX is the only long-term solution.

What is a Pressure Reducing Valve and do I need one? This bell-shaped device regulates high city pressure (often over 100 PSI) down to a safe level for your home. PRVs have a lifespan of 10-15 years. A faulty PRV can cause both high and low pressure issues. Principle Plumbing can test your PRV and replace it if needed to protect your pipes and appliances.

Why do my pipes make loud banging noises? Banging or shuddering pipes is known as "water hammer". Water hammer happens when flowing water is suddenly forced to stop, like when a faucet or valve shuts quickly. This creates a pressure spike that makes pipes bang or thud against walls or each other. High pressure silently destroys appliances like dishwashers and washing machines, causes dripping faucets, and increases the risk of a catastrophic pipe burst.

Our Diagnostic Process: A Scientific Approach to Finding the Cause

We don't guess—we test. Our licensed, insured & bonded plumbers follow a meticulous diagnostic process to identify the source of your water pressure issue.

Comprehensive Testing & Inspection

We begin with a baseline static pressure test at your outdoor hose spigot to get an accurate reading of the pressure being delivered to your home from the we bring years of experience municipal supply.

This tells us if the problem originates inside or outside your house, giving us a clear starting point for our investigation.

What We Check:

  • Baseline Static Pressure Test: Specialized pressure gauge connected to your outdoor hose spigot for accurate PSI readings.
  • PRV Inspection: Testing your Pressure Reducing Valve (found in most homes built after 1990) for proper function.
  • Leak Detection: Checking for hidden leaks in your main service line or beneath your foundation that could cause pressure drops.
  • Pipe Condition Assessment: Evaluating older galvanized steel pipes for mineral scale buildup common with we bring years of experience's hard water.

Trust Principle Plumbing for accurate diagnostics that identify the real problem.

Permanent Solutions Tailored to Your Home

Once we've diagnosed the problem, we provide a clear, upfront estimate for the right solution. We don't just identify issues—we fix them permanently.

Whether it's high pressure, low pressure, or inconsistent flow, we have the expertise and equipment to restore your water system to optimal performance.

SOLUTIONS WE PROVIDE:

  • PRV Installation & Replacement: Install high-quality Pressure Reducing Valves from trusted brands like Zurn and Watts to protect your entire home from high pressure damage.
  • Leak Repair: Pinpoint and repair hidden leaks in your main service line or foundation to restore normal pressure.
  • Pipe Replacement (Repipe): Replace old, clogged galvanized pipes with modern copper or PEX piping for long-term reliability.
  • Water Pressure Booster System: Install pump systems to increase your home's water pressure to ideal levels when municipal supply is insufficient.

PROFESSIONAL EXPERTISE:

Our licensed technicians have the advanced tools and training to diagnose complex pressure issues accurately. We provide comprehensive solutions that address the root cause, not just the symptoms.

With Principle Plumbing, you're choosing experienced professionals who understand the dynamics of your home's plumbing system.

Main Water Line Services & Replacement

Your main water line is critical to your home's water supply. We provide expert repair, replacement, and upgrade services to ensure reliable water delivery.

Main Water Line Replacement

Your main water line runs from the street to your home, typically buried 5-6 feet underground. When this line fails due to age, corrosion, or tree root intrusion, we replace it with modern materials like copper or PEX that will last for decades.
