Why Is My Water Pressure So Low? Common Causes & Fixes
Few things are more frustrating than turning on the tap and watching the water trickle out. Whether it’s a weak shower or slow-filling sink, low water pressure can interrupt your daily routine and signal deeper plumbing problems. The good news? With a few simple checks (and the right help), you can get your water flow back to normal.
What Causes Low Water Pressure in Your Home?
If you’re dealing with low water pressure in your house, there’s usually an underlying cause—anything from a minor blockage to a serious leak. Understanding what’s behind the issue can save you from unnecessary repairs and get things flowing again sooner.
Common culprits include pipe blockages or mineral build-up, faulty taps, aerators, or pressure regulators, hidden leaks in your plumbing system, or problems with your main water supply. Identifying the root cause early not only restores your water flow but also helps protect your home from long-term damage.
Pipe Blockages and Mineral Build-Up
Over time, pipes can collect limescale, rust, or sediment, restricting the flow of water. If you notice uneven shower pressure or taps that seem slower than usual, your plumbing might be clogged.
Professional cleaning or inspection can quickly clear the obstruction and prevent further buildup. If you suspect this might be the cause, check out our Blocked Drains & Burst Pipes services for expert help.
Faulty Fixtures or Pressure Regulators
Sometimes the issue is as simple as a blocked tap or a malfunctioning pressure regulator. Try cleaning the aerators on your taps or checking for buildup in your showerhead. If that doesn’t improve the flow, your regulator may need adjustment or replacement.
Our Plumbing Maintenance Services and shower repair experts can inspect, repair, or replace faulty components to restore steady pressure.
Hidden Leaks in the Plumbing System
Even a small leak can cause a noticeable drop in water pressure—and waste hundreds of liters of water over time. Keep an eye out for damp walls, dripping sounds, or unusually high water bills.
If you suspect a hidden leak, call our team for professional Leak Detection. We use advanced tools to pinpoint leaks quickly and prevent further damage.
Why Is My Hot Water Pressure So Low?
If only your hot water seems affected, the problem could lie within your hot water system. Sediment buildup inside the tank, a faulty tempering valve, or a partially closed isolation valve can all cause weak flow.
Persistent low hot water pressure might require a professional inspection of your Hot Water Services or Water Heater Installation setup to make sure everything’s working efficiently.
How to Fix Low Water Pressure
If you’re dealing with low water pressure in your home, start by looking for common causes. Check for pipe blockages or mineral build-up, inspect taps, aerators, and pressure regulators for faults, and keep an eye out for hidden leaks or issues with your main water supply. Identifying and addressing these problems early can restore proper water flow and help protect your home from long-term damage. If the issue continues, it’s best to book our Plumbing Maintenance Services for a lasting fix.
