How to Increase Water Pressure in Your Home

Is your shower more of a slow drizzle than a refreshing blast? Low water pressure can turn simple tasks like washing dishes or rinsing your hair into a frustrating chore.

If you’ve noticed a weak flow from your taps or appliances taking longer to fill, you’re not alone − it’s a common issue in many homes.

Fortunately, there are several practical steps you can take to improve your home’s water pressure. Whether the cause is minor or something more serious, this guide will walk you through what to look for and how to fix it.

From checking for leaks to upgrading your plumbing or installing a pressure booster, you’ll find solutions that fit your needs and budget. Let’s get started and get your water flowing strong again.

Identify the Cause of Low Water Pressure

Before jumping into fixes, it’s important to figure out what’s actually causing the drop in water pressure. Sometimes it’s a quick fix − other times, it points to a bigger issue.

Here’s how to start narrowing it down:

• Check multiple taps: Is the low pressure happening at just one fixture or throughout the house?
• Test hot and cold water: If it’s only the hot water with weak flow, your water heater might be the culprit.
• Inspect showerheads and taps: Mineral build-up can clog outlets, reducing water flow.
• Ask your neighbours: If they’re having the same issue, the problem may be with the main water supply.
• Monitor pressure over time: Is it always low or does it drop at certain times of day?

Figuring out where the issue lies helps you target the right plumbing solution, saving time, money and frustration down the track.

Check for Clogged Pipes or Fixtures

Clogged pipes or fixtures are a common cause of low water pressure, especially in older homes. Over time, mineral deposits, rust, and debris can build up and restrict water flow.

Here’s what to look out for:

• Tap aerators: Unscrew the aerator at the end of your tap and check for dirt or limescale. A quick soak in vinegar can clean it up.
• Showerheads: If your shower has turned into a slow trickle, mineral buildup might be blocking the nozzles. Try soaking the showerhead in vinegar or replacing it.
• Visible pipe buildup: If you have exposed pipes, look for signs of corrosion or buildup around joints.
• Uneven pressure in fixtures: If only certain areas have low pressure, the blockage might be in a specific section of pipe.

If cleaning doesn’t help, you might need a plumber to flush out or replace parts of your plumbing system.

Inspect the Pressure Regulator

If your whole house is experiencing low water pressure, the issue could be your pressure regulator. This device controls the water pressure coming into your home from the main supply line.

When it’s working properly, it keeps the pressure at a safe and consistent level. But if it’s faulty or set too low, it can seriously affect how much water comes through your taps.

Start by locating the regulator − it’s usually near where your main water line enters the house. Most models have a screw or bolt you can adjust. Turning it clockwise will usually increase the pressure, but be careful not to go too high, as that can damage your pipes and appliances.

If adjusting doesn’t help, the regulator itself might be worn out and need replacing. In that case, it’s best to call a licensed plumber to inspect and install a new one safely.

Look for Leaks in the Plumbing System

Leaks can quietly drain your water pressure without you even noticing. When water escapes through cracks or holes in the pipes, less of it makes it to your taps.

Here’s how to spot a possible leak:

• Check your water meter: Turn off all taps and appliances, then watch the meter. If it keeps ticking, there’s likely a hidden leak.
• Look for damp spots: Water stains on walls, ceilings, or floors could be a sign of leaking pipes behind the scenes.
• Inspect under sinks: Check for moisture or pooling water around fittings and joints.
• Watch your water bill: A sudden spike with no clear reason could mean water is leaking somewhere.
• Listen carefully: A faint dripping or hissing sound inside walls might point to a leak.

Even small leaks can affect pressure. If you suspect one, it’s best to get a plumber to investigate quickly.

Clean or Replace Old Plumbing

Old or corroded pipes can be a major reason your water pressure isn’t up to scratch. Over time, mineral deposits and rust can build up inside your plumbing, narrowing the pipes and restricting water flow. This is especially common in older homes with galvanised steel pipes, which tend to corrode from the inside out.

If you’re noticing poor pressure throughout the house and your plumbing is decades old, it might be time for an upgrade.

In some cases, a professional plumber can clean out certain sections of pipe, but often the best long-term fix is replacing them entirely with modern materials like copper or PEX. These newer pipes are more durable and allow water to flow more freely.

Upgrading your plumbing might sound like a big job, but it can make a massive difference in water pressure, reliability, and overall home value. It’s a smart investment that pays off over time.

Install a Water Pressure Booster Pump

If your water pressure is consistently low − even after checking for leaks, blockages or regulator issues − it might be time to consider a water pressure booster pump.

These handy devices increase the pressure in your home’s water system, especially if the supply from the mains is weak. Here’s what to know:

1. How it works: A booster pump draws water in and uses an electric motor to push it out at a higher pressure.
2. When to use one: Ideal if you live in a multi-story home, on a hill, or at the end of a mains line where pressure tends to drop.
3. Types available: Pumps come in different sizes and strengths, depending on your home’s needs.
4. Professional installation recommended: To ensure safety, efficiency, and compliance with plumbing codes.
5. Bonus benefit: It can improve performance in showers, dishwashers, washing machines and garden hoses.

It’s a powerful upgrade for long-term water flow improvement.

Contact Your Water Supplier

If you’ve tried everything inside your home and the water pressure is still low, it’s time to check in with your water supplier.

Sometimes, the problem isn’t in your plumbing at all − it could be coming from the main water supply line. Municipal water systems occasionally reduce pressure for maintenance, safety or due to high demand in your area.

Give your local water authority a call and ask if there are any known issues or restrictions affecting your property. They may be able to tell you what’s going on or even send someone out to test the supply pressure at your meter.

In some cases, the supplier can adjust the main pressure or recommend solutions specific to your area. It’s also a good idea to check whether your neighbours are experiencing the same issue − that can help pinpoint if it’s a wider problem. Don’t be afraid to ask questions − they’re there to help.

Ready to Boost Water Pressure?

Low water pressure can be a real annoyance, but the good news is that there are plenty of ways to fix it. Whether it’s a simple clean of your showerhead, a check for leaks or upgrading to a pressure booster pump, you’ve got options to get your water flowing properly again.

Start by identifying the cause − sometimes it’s as easy as adjusting the pressure regulator or clearing a blocked tap. And if the problem runs deeper, don’t hesitate to call in a professional plumber for expert advice and repairs.

Remember, good water pressure doesn’t just make life more convenient − it also helps your appliances run more efficiently. With a few smart moves, you can enjoy stronger showers, faster fills and smoother water flow throughout your home. Ready to boost your water pressure? You’re now set to take action.
