Detecting and Plugging Hidden Leaks

More Savvy Tips

Anytime you get an extraordinarily high water bill, it's time to investigate for hidden leaks. Your toilet is one possible culprit, according to Albert Nahman, owner of Albert Nahman Plumbing, a Diamond Certified company. To see if it's leaking, put a drop or two of food coloring into the tank. Wait a few minutes. If the color shows up in the toilet bowl, you've got a leak. Usually the flapper needs to be replaced. Underground leaks can also run up your bill. To detect those, Mr. Nahman says turn off the valve and make sure no live water is coming out of the faucets. Then go to your meter box. If the red indicator is spinning, you have a leak somewhere in the delivery pipe to your house. Underground leaks may cause wet spots in your yard, but sometimes there's no visible clue.
