Plumbing leaks might not always be obvious

A leak in your plumbing can be mighty costly. Most people find out about it when they get a water bill for hundreds of dollars more than normal.

That's because a leak may not be obvious.

"If you can find all the leaks in your home, you might be able to save $200 a year on you water bill," said Cheryl Reed with Angie's List.

Some of the possible culprits?

"A leaky toilet tank flapper, dripping faucets - you'd be amazed how much that adds up over time and garden hoses the leak onto the ground that you don't even notice," she said.

And of course, there could be a broken pipe. If you notice a musty smell, or a stain on the ceiling, don't ignore it.

And be aware of these other warning signs:

"Peeling wall paper or even dampness, you'll see it at the wall as buckling possibly or maybe your cabinetry is buckling, that's a good indication, but your nose may lead you there first," Reed said.

If you have a leak and don't deal with it, you could find yourself faced with fighting mold – and that's something you don't want to happen because the cleanup can cost thousands.
