Understanding and Fixing Low Water Pressure in Your Home
Understanding and Fixing Low Water Pressure in Your Home
Hello, this is the team from Nexus Plumbing.
Today, we want to talk about water pressure in your home. It’s frustrating when you’re trying to work in the kitchen or take a shower, and the water flow is weaker than you’d like. On the other hand, an unstable, sputtering shower can easily ruin your morning.
There are several reasons why you might be experiencing low water pressure. Identifying the cause will help you choose the best way to solve the problem.
1. Low Water Pressure Throughout the Entire House
-
✓ Old supply pipes: 15mm or 20mm pipes can limit flow. Newer homes use 25mm.
-
✓ Hot water cylinder issues: Low-pressure cylinders lead to weak hot water flow.
-
✓ PLV problems: A faulty Pressure Limiting Valve can reduce pressure throughout the house.
-
✓ Leaks: Undetected leaks inside or outside can lower pressure significantly.
2. A Sudden Drop in Water Pressure
Sudden pressure drops can be alarming. Here are some key scenarios:
-
✓ One tap affected: Clogged filters or a failing tap fixture are common culprits.
-
✓ Whole house drop: May indicate a burst pipe or faulty Pressure Limiting Valve.
-
✓ Hot water only: Your hot water cylinder may have a faulty valve that needs professional attention.
3. Low Water Pressure Only in the Shower
If your shower is the only fixture with low pressure:
-
✓ Blocked showerhead: Mineral deposits can restrict water flow.
-
✓ Faulty shower mixer: If the issue isn’t the showerhead, internal plumbing may be the cause.
Determine if the issue affects your entire home or just one area. This will help your plumber resolve the issue quickly and accurately.
