Considering the majority of a home's plumbing system is enclosed behind drywall, it can sometimes be difficult for homeowners to diagnose a leaky pipe until it becomes a full-on pipe burst. However, homeowners should be aware that there are a few common signs of a leaky pipe that can help to locate the problem and have it repaired by a plumber before any extensive (and costly) damage is done.
An Unusually High Water Bill
More than likely, your water bill is pretty consistent from month-to-month. Therefore, you should keep an eye out for unexplained spikes in your bill. This could be indicative of higher-than-usual water consumption due to a leaky pipe within your walls or ceiling.
Dark Spots on Walls or Ceilings
Another possible sign of a water leak in your home could be dark spots on your ceiling or walls. As water leaks from a pipe and drips down onto the same area of drywall, it can eventually cause the drywall to break down, saturate, and become darker in color. If spraying the area with a cleanser and scrubbing it doesn't get rid of the discoloration, there's a good chance you're dealing with a water leak in that area of your home.
Sudden Drop in Water Pressure
Have you recently noticed that your water pressure is lower throughout the house? Maybe you've noticed this when you've done dishes, washed your hands in the sink, or taken a shower. One common cause of lower water pressure could be due to a leaking pipe. The larger the leak, the more water is being redirected and the lower your water pressure will be as a result. Of course, there are other possible causes of low water pressure as well (including tree roots growing into exterior pipes), but this is one possible cause to consider.
Odd Noises Coming From Walls
Finally, if you find that you hear odd thumping or knocking sounds in your walls (especially when you turn on faucets), this could be a sign of a water leak as well. Another sign to be on the lookout for is the sound of rushing water when no plumbing appliances (dishwasher, clothes washer, etc.) are currently in use throughout the house.
If you have noticed one or even several of these telltale signs, now would be a good time to call a plumber to have an inspection for leaky pipes done in your home.
