The Water Pressure at Home is Dropping

The Water Pressure at Home is Dropping

Low water pressure is more than just an inconvenience—it can be a sign of a deeper plumbing issue. Whether you’re brushing your teeth, running the dishwasher, or trying to enjoy a relaxing shower, reduced water pressure disrupts your daily routines and could point to hidden problems in your home’s plumbing system.

But how do you know when it’s time to call a professional plumber? Here’s a detailed guide to help homeowners and plumbers decide the right course of action when the water pressure starts to drop.


Common Causes of Low Water Pressure

  1. Mineral Build-up in Pipes

Over time, mineral deposits from hard water can accumulate inside your plumbing pipes, reducing the flow of water. Areas with hard water are particularly prone to this problem, and once it starts, it tends to worsen if left unaddressed.

  1. Leaky Pipes

A hidden leak in your plumbing system can drastically reduce water pressure. Not only does this waste water (and increase your bill), but it can also cause significant property damage if not handled quickly.

  1. Clogged Fixtures

Sometimes, the issue lies in your faucets or showerheads. Dirt, debris, or limescale can clog fixtures, reducing the water flow. While this is often something you can fix yourself, it’s important to rule out more serious causes.

  1. Faulty Pressure Regulator

If your water pressure is fluctuating or uniformly low, the pressure regulator might be faulty. This part ensures your water pressure remains at a safe, functional level, so any issues with it need immediate attention.

  1. Main Water Line Problems

Sometimes, low water pressure originates outside your home. Damage to your main water line, aging utility infrastructure, or municipal water supply issues can affect overall pressure.

When Should You Call A Rescue Rooter

While some causes of low water pressure are simple enough to tackle on your own, others require the expertise of a professional. Here are some scenarios when calling a plumber—like Rescue Rooter in Southern Ontario—is your best bet:

1. You Can’t Find the Source of the Problem

If you’ve checked for clogged fixtures, leaks, or a failing pressure regulator and can’t identify the issue, it’s time to call in the pros. A professional plumber has the tools and experience to diagnose the root cause quickly.

2. You Suspect a Hidden Leak

Water leaks aren’t always obvious; they may occur behind walls, under floors, or in your outdoor plumbing. If your water pressure is dropping and you notice damp patches, unexplained water bills, or musty odors, a plumber should investigate immediately.

3. The Entire Home is Affected

If the water pressure is low throughout the house (not just in one or two fixtures), this could be a sign of a larger issue, such as a damaged main water line or a problem with your pressure regulator.

4. There’s a Sudden and Significant Drop

A sudden drop in water pressure can indicate a burst pipe or other significant damage. This requires immediate attention to prevent further harm to your home.

5. DIY Fixes Aren’t Working

Tried cleaning the faucet or replacing parts but still facing low water pressure? Don’t waste time—call a plumber who can address the underlying problem effectively.
