Plumbing related water damage is a common occurrence. Often plumbing leaks are designated as minor problems or annoyances rather than serious concerns in need of professional attention.
houzz.com published an informative piece on plumbing repairs and the many reasons hiring a licensed plumber is proactive prevention.

“You might think a running toilet or leaky faucet is a trivial issue in your home, something for your handyperson to take on later when you’ve got other jobs around the house to do. But make no mistake: Never skip a drip. Leaks, even minor ones, can amount to big increases on your water and even heating bill. “You’d be surprised at how much is going down the drain and how much you’re paying by not getting it fixed,” says plumber Scott Campbell of Central Penn Plumbing Services in Pennsylvania.

What’s more, fixing leaky faucets and toilets make up the majority of what most professional plumbers do, and trying to fix a faucet yourself, or hiring your neighbor’s uncle, can lead to serious issues. “It’s a quick and easy fix, but still something you want to call a professional about,” Campbell says.”
