Tackling Low Water Pressure: Causes and Solutions


Water pressure, while often overlooked, is a crucial aspect of our daily routines. From the refreshing showers we take in the morning to efficiently washing dishes and laundry, optimal water pressure plays an integral role in ensuring our home’s functionality and our comfort. Imagine trying to rinse shampoo out of your hair with just a trickle of water or waiting endlessly for a pot to fill up at the sink. It’s not just about convenience; consistently low water pressure can signal more significant underlying plumbing issues.

For the residents of Illinois, fluctuations in water pressure can be a common concern due to various reasons ranging from municipal supply issues to individual household plumbing challenges. That’s where King Heating, Cooling & Plumbing steps in. With a reputation built on trust and expertise, they’ve been the go-to experts for many Illinois homeowners facing water pressure woes, ensuring that their homes are running seamlessly and efficiently.

Understanding Water Pressure

Water pressure is the force exerted by water as it moves through pipes and fixtures. Just like blood pressure in our veins, water pressure is vital for the effective operation of home plumbing systems.

What is Water Pressure?

At its core, water pressure determines how forcefully water comes out of your taps and showerheads. It’s measured in pounds per square inch (PSI), and its level can make the difference between a satisfying shower and a frustrating trickle. An efficient plumbing system ensures that water is delivered throughout a house at a consistent and adequate pressure.

Ideal Water Pressure Range

For most residential homes, a water pressure between 45 to 60 PSI is considered optimal. If the pressure drops below this range, homeowners may notice a significant decline in water flow, while pressure above this range can lead to wear and tear on your plumbing fixtures and pipes.

Common Causes of Low Water Pressure

There can be multiple culprits behind diminished water pressure in a home.


– Clogged Pipes

Over time, mineral deposits, sediment, and other debris can accumulate in pipes, leading to obstructions. These blockages restrict the flow of water, causing a noticeable drop in pressure. Such clogs can be localized, affecting a single fixture, or widespread, affecting the entire house.

– Corroded Plumbing

Pipes, especially older iron ones, can corrode internally over decades of use. As corrosion builds up, the inside diameter of the pipe shrinks, impeding water flow. Homes with plumbing over 20 years old may experience reduced water pressure due to this reason.

– Leaking Pipes

Leaks divert water away from its intended destination. A significant leak can lead to a noticeable drop in water pressure. Additionally, leaks can result in water damage and increased utility bills.

– Faulty Valves

Sometimes, the main shutoff valve might not be fully open, which can reduce water flow. It’s essential to ensure both the main valve and the water meter valve are entirely open.

– Municipal Issues

Occasionally, the issue might lie outside your property. Low water pressure can be due to problems with the municipal supply, such as mainline breaks or maintenance work.

Identifying the Problem

Before diving into solutions, it’s crucial to diagnose the root of the problem.

DIY Checks

Start by determining if the low pressure affects a single fixture or the entire house. Check the aerators on faucets for buildup, and ensure valves are fully open. Observe the water pressure at different times of the day; sometimes, municipal supplies can be low during peak usage hours.

When to Call a Professional

If basic checks don’t reveal the issue, or if the problem is widespread, it’s time to call in the experts. King Heating, Cooling & Plumbing boasts seasoned professionals who can diagnose and rectify water pressure problems efficiently.

Solutions to Restore Optimal Water Pressure

Once the issue is identified, it can often be rectified with some targeted solutions.


– Pipe Replacement

For homes with old, corroded plumbing, replacing pipes might be the best long-term solution. Modern pipes made of copper or PVC are more resistant to corrosion.

– Clean or Replace Clogged Faucets

Cleaning aerators and showerheads can resolve localized low pressure. If there’s significant buildup, consider replacing the fixtures.

– Pressure Boosters

For homes that suffer from chronically low municipal water pressure, installing a pressure booster pump can amplify the water pressure, ensuring optimal flow throughout the house.


Low water pressure can be a minor inconvenience or a sign of deeper plumbing issues. By understanding its causes and solutions, homeowners can ensure a more comfortable and functional living environment. With King Heating, Cooling & Plumbing’s expertise, residents of Illinois can confidently address and overcome any water pressure challenges, guaranteeing peace of mind and consistent water flow.
