How do you check for leaks in plumbing systems?

Performing a pressure test or visually inspecting for water damage is a reliable method to check for leaks in plumbing systems. A pressure test involves sealing the system and applying air or water pressure to it. If there’s a leak, the pressure will drop, indicating that there is a breach in the system. This method is particularly useful as it allows for an accurate assessment of the integrity of the pipes.

Visual inspection is equally important; it involves looking for signs of water damage, such as mold growth, discoloration on walls or ceilings, or dripping water. These indicators can reveal hidden leaks that may not be immediately apparent.

Other methods, while useful in certain contexts, may not provide conclusive evidence of leaks. Observing air bubbles in the water supply is not a standardized method for leak detection, as air bubbles can occur for various reasons unrelated to leaks. Listening for unusual sounds in pipes might indicate issues such as water hammer or other problems, but it doesn't directly confirm the presence of a leak. Checking the water meter for continuous flow can indicate leaks if the water is not being actively used, but it may not pinpoint the location or the cause. Therefore, the combination of pressure tests and visual inspections remains the most effective way to identify leaks in plumbing systems.
