Your home’s plumbing system works hard behind the scenes, but hidden issues can lead to skyrocketing water bills, costly repairs, and even property damage if left unchecked. At Curran, we’ve seen firsthand how undetected plumbing problems can drain your wallet. Here are some common hidden plumbing issues to watch out—and how you can stay ahead of them.

Leaking Pipes
Even a small, unnoticed leak can waste litres of water every day, leading to a spike in your water bill. Hidden leaks often occur behind walls, under floors, or in ceilings, making them difficult to detect. Look out for damp patches, mould growth, or an unexplained increase in water usage. If you suspect a leak, our expert plumbers can perform a thorough inspection using advanced leak detection technology.
Silent Toilet Leaks
A toilet that constantly runs or has a slow, silent leak can waste thousands of litres of water a year. An easy way to test for this is by adding a few drops of food colouring to the toilet cistern—if the colour appears in the bowl without flushing, you have a leak. Our team can replace worn-out components to stop the wastage and save you money.
Blocked or slow drains
A slow drain might not seem like a big issue, but it can indicate a deeper problem, such as a partial blockage or tree root intrusion in your pipes. Left untreated, this can lead to full-scale backups and expensive repairs. Regular drain cleaning and inspections can help prevent these costly disruptions.
hidden pipe corrosion

Older homes or properties with outdated plumbing may have pipes that are corroding from the inside out. Signs include discoloured water, low water pressure, or frequent leaks. Replacing ageing pipes before they burst can save you from costly emergency repairs.
High water pressure issues
While strong water pressure might feel great in the shower, excessive pressure can stress your pipes, leading to leaks and damage over time. If you notice unusually high-water pressure, installing a pressure regulator can help protect your plumbing system.
Hot water inefficiencies
Aging or poorly maintained hot water systems can lead to higher energy costs and inconsistent hot water supply. Sediment buildup in the tank reduces efficiency, causing the system to work harder and use more energy. Regular maintenance can extend your hot water heater’s lifespan and improve its performance.
