Watch for slow drains, recurring clogs, dripping faucets, running toilets, low water pressure, or sudden spikes in your water bill. Stains on ceilings or walls, musty odors, or warm spots on floors can indicate hidden leaks that need prompt attention. If you hear banging pipes or notice discolored water, it's smart to have a professional inspection. Addressing minor issues early prevents water damage, mold growth, and costly structural repairs. If problems come and go, keep notes of when they happen so your plumber can find the cause faster. If you're unsure, a quick camera check or pressure test can confirm what's really happening inside the lines.
