This is where homeowners often misunderstand the problem.
Weak water pressure can have many possible causes.
The pump is only one part of the water system.
Common causes can include:
- Insufficient incoming water pressure
The available water supply may already be weak. - Pump incorrectly selected or sized
The existing pump may not be suitable for the actual water demand or system. - Clogged water filter
A dirty or blocked filter can restrict water flow and reduce pressure downstream. - Old or restricted piping
Ageing pipes may suffer from internal corrosion, deposits or restrictions that reduce water flow. - Undersized piping
Pipe diameter can affect how much water can flow through the system. - Partially closed or faulty valves
A valve that is not fully open or has failed internally can restrict water flow. - Several outlets being used simultaneously
Opening multiple showers and taps increases the total water demand. Pressure may drop if the system cannot supply the required flow. - Pump or system problems
Worn pump components, incorrect settings, air in the system, leaks or other faults may affect performance.
- Insufficient incoming water pressure
From Our Experience
When a homeowner complains about weak pressure, simply replacing the existing pump with a larger pump is not always the correct solution.
The water source, pump, filter, valves, piping and household demand work together as one system.
Understanding the cause of the problem should come before selecting the solution.
