Detecting Leaks Around the House:

  • Check the Garden: Look at hoses, faucets, and drip irrigation systems.
  • Check the line running from the meter to the house: While this may sound difficult. However, it may save you money if you locate the leak for the plumber.

If you know you have a shuf-off valve by the house, shut if off temporarily and check the meter by removing the lid and watching register on top of the meter.

If you can't see the meter register, try digging around because they sometimes have dirt or grass covering the top of them. Once you locate it and the valve is turned off by the house, watch the meter to see if it is turning.  If it is still turning, then the leak is between the meter and the house.

At this point, walk the area between the meter and the shut-off valve.  Look for signs of a leak such as: soft muddy areas, grass that is greener than the rest or growing much faster than other areas.  If you see such an obvious sign, call the plumber or assess if you can make a repair yourself.

  • Check the showerhead for leaks: It should be a fairly straightforward home repair if this is a source of leaking.
  • Check the toilet for leaks: Check the toilet for leaks by removing the top off the tank and listening very closely.  If you hear any hissing at all, try to locate where it is coming from.  If you locate the area where the leak is coming from, assess it and determine if you can fix it.  If you can't, then call a plumber.  You can also add food coloring to the tank and if it leaks out into the bowl it usually will be an indication to change out the flapper.  You can also check the tank water level in comparison to the filler pipe. If the water level is close to the top rim of this pipe any vibration can potentially cause the toilet to run unnecessarily. To correct this adjust the ball cock lower in the tank an upon flushing it will lower the tank water level.
