Not all leaks are as obvious as a dripping faucet. If you hear water running
in your home when no water’s in use or your water usage is suddenly
higher than expected, you might have a water leak. If you have a metered
well, the steps below can help to find out if there's a leak on your property
and where it’s coming from.
Find out if you have a leak
Turn off all of your water fixtures and appliances (don’t forget
the ice maker, water filtration system and other systems), then find your
Depending on the type of meter you have, you’ll see either a red
flow indicator or a sweep hand. If
the sweep hand or flow indicator is still moving after you’ve turned
off all of the water in your home, you might have a leak.
Turn your water fixtures and appliances back on, but try not to use them
until you know where the leak’s coming from.
Find the source
The next step is to find the source of the leak. Turn off fixtures and
appliances one by one, checking the meter after you turn each one off.
If the flow indicator or sweep hand is still moving when you check the
meter, you haven't found the leak yet. Continue turning off fixtures and
checking the meter until the meter stops—then you’ll know
you’ve found the source.
Items to turn off include:
- Toilets, which can be turned off at the base
- Faucets, which can be turned off below the sink
- Sprinkler systems, water softeners, swamp coolers, ice machines and
reverse osmosis units, all of which have a bypass valve that lets water
bypass the unit
Check the main service line
If you still haven't found the problem, try checking the main service
line. Find the water shutoff valve to your home. It will be either in
your front yard, in your garage, or near your water softener. Shut off
this valve, turning off all water to your home. Turn on a faucet to make
sure there is no water, then check the meter. If the meter is still moving,
the leak is most likely between the shutoff valve and the water meter.
If you've found your leak, you may be able to fix it yourself. Repairs
to toilets and faucets can be fairly simple, while other leaks may need
a professional plumber. Don't get in over your head. If you're not sure
you can fix it, call a professional.
