Low water pressure can be a frustrating problem that affects your daily routines, from showering to washing dishes. There are several reasons why your home might be experiencing low water pressure, ranging from simple issues like a partially closed valve to more complex problems such as pipe leaks and blocked drains. In the following guide, our plumbers at The Local Plumber Melbourne will walk you through the most common causes of low water pressure and provide some simple solutions to hopefully help you restore optimal water flow to your home.
Common Causes of Low Water Pressure
Understanding the underlying cause of low water pressure is the first step toward fixing it. Based on our daily experiences in helping our fellow Melbourne, here are some of the most common reasons that we typically encounter
1. Partially Closed Valves
The main water valve or the shut-off valve may not be fully open. This is a common issue that can occur if someone has recently worked on your plumbing system and did not fully reopen the valve afterward.
2. Clogged Pipes
Over time, mineral deposits and debris can build up inside your pipes, narrowing the passage and reducing water flow. This is especially common in older homes with galvanized steel pipes that are prone to corrosion over time. This issue proliferates when foreign objects (e.g toiletries, hand wipes, food, hair etc) are regularly flushed down your drains..
3. Leaks in your Plumbing System
Leaks can significantly reduce water pressure by allowing water to escape before it reaches your fixtures. Signs of leaks include damp patches, mold, or unusually high water bills. We have recently released an article detailing why water is leaking through your wall if you wish to learn more.
4. Faulty Pressure Regulator
A pressure regulator, or pressure-reducing valve, controls the water pressure in your home. If it becomes faulty or malfunctions, it can cause either excessively low or high water pressure.
5. Council Water Supply Issues
Sometimes, low water pressure is not due to a problem within your home but rather an issue with your local council’s water supply. This could be due to maintenance work, a water main break, or general low supply in your area.
How Can I Increase My Water Pressure?
Once you have identified the potential cause of low water pressure, there are several steps you can take to fix the problem. Please note, we highly recommend contacting a local plumber before undertaking any of the following.
1. Check and Fully Open the Main Water Valve
Locate your home’s main water valve, usually near the water meter or where the water supply enters your home. Ensure the valve is fully open, as a partially closed valve can significantly reduce water flow.
2. Clean or Replace Clogged / Outdated Plumbing Fixtures
Low water pressure can sometimes be traced back to a single fixture, such as a showerhead or tap. Mineral buildup can clog aerators and restrict flow. Remove these fixtures, soak them in vinegar to dissolve the deposits, or replace them if cleaning is ineffective.
3. Flush Out Your Pipes
Sediment and debris can accumulate in your pipes over time. Flushing your plumbing system can help clear these blockages. Turn on all taps in your home simultaneously and let them run for a few minutes to push out any built-up debris. Some methods to flush out your drains include jet blasting and drain snakes by using a cctv drain inspection to identify exactly where the blockage is.
4. Check for Leaks and Repair Them
Inspect your home for signs of leaks, such as damp spots, mold growth, or an unusually high water bill. If you suspect a leak, turn off all taps and check your water meter. If the meter is still moving, you may have a hidden leak. A professional plumber can help locate and repair leaks effectively.
5. Inspect the Pressure Regulator
If your home has a pressure regulator, check if it is functioning correctly. A faulty regulator can cause inconsistent water pressure. A plumber can test the regulator and replace it if necessary to restore normal pressure levels.
6. Install a Water Pressure Booster Pump
If the water pressure in your area is generally low, consider installing a water pressure booster pump. This device increases water pressure as it enters your home, ensuring a consistent and reliable flow. A professional plumber can install and set up the booster pump to ensure it operates efficiently.
7. Replace Old or Corroded Pipes
If you live in an older home with galvanized steel pipes, corrosion might be restricting water flow. Replacing and relining old pipes with modern materials like copper or PEX can significantly improve water pressure and reduce the risk of leaks and other plumbing issues.
Preventative Measures to Maintain Optimal Water Pressure
To prevent future water pressure problems, consider the following:
- Regular Maintenance: Schedule regular inspections of your plumbing system to identify and fix potential issues early.
- Install Water Softeners: If you have hard water, installing a water softener can prevent mineral buildup in your pipes and fixtures, maintaining good water flow.
- Upgrade Plumbing Fixtures: Modern fixtures are designed to be more efficient, improving water pressure while reducing water usage.
When to Call a Professional Plumber
While many water pressure issues can be resolved with simple DIY steps, some situations require professional assistance. Contact a professional plumber if:
- You cannot identify the cause of low water pressure.
- There are multiple leaks or significant damage to your plumbing system.
- You need to install a water pressure booster pump or replace corroded pipes.
