Low water pressure can signal serious plumbing issues. Learn the causes and when to call a professional.
Common Causes of Low Water Pressure in Caloundra
Low water pressure is frustrating and can have several root causes. The most common in Caloundra homes are: corroded or scaled pipes (especially in homes built before 1990), a faulty pressure limiting valve (PLV), a leak somewhere in the system, or issues with the local council water supply.
Check Your Pressure Limiting Valve First
Most Caloundra homes have a PLV installed at the meter. These devices have a lifespan of about 10 years and can cause significant pressure drops when they begin to fail. Replacement is a straightforward job for a licensed plumber and typically costs $250–$400 all-inclusive.
Pipe Corrosion & Scaling
Older homes in Caloundra often have galvanised steel pipes that corrode from the inside over time, dramatically reducing water flow. The only fix is repipe — replacing with modern PEX or copper. PumiFlow offers competitive quotes on full home replumbing.
When It's a Council Issue
Sometimes the problem is upstream of your property. If multiple neighbours are experiencing similar issues, contact Sunshine Coast Council's water network team. We can help you document the issue if needed.
