Signs that You Might Have a Plumbing Leak
Some plumbing leaks are obvious. "Gusher leaks," stemming from a burst or separated pipe, spew out a major amount of water. However, other types are harder to detect. Stay alert and use your eyes, ears, and sense of smell to tell you when your plumbing is leaking. Here are some possible signs:
● Strange noises from your plumbing system like hissings, gurglings, or the sound of endlessly running water.  ● Discolored, bubbling, peeling, or damp patches on ceilings, walls, or floors. ● A "hot spot" on your floor which may indicate a hot water leak below. ● Water anywhere it shouldn't be: on the bathroom floor after a shower (even though you had the shower door or curtain closed), around the           base of your toilet, inside an under sink cabinet, or beneath your water heater. ● Cracking, buckling, or loose flooring material. ● A musty odor which could indicate mold. ● A water meter that registers usage even when no water source is turned on. ● An inexplicably muddy section of your yard, with greener grass than on the rest of your lawn.
