This is the first photo that demonstrates that the water meter is not running.
This is your baseline photo.
This second photo shows that the meter is still not running.
This final photo, showing that the water meter is still not running,
confirms that there are no hidden and undiscovered water leaks in the house,
and that the inspector didn't leave any faucets running anywhere.
It's best if the photos are actually time-stamped and show several seconds between each shot. Since some cameras don't come with this feature, take each photo from a slightly different angle to show that they are, in fact, different. But make sure that the meter's display can be viewed--the angle shouldn't distort the reading.
Of course, if these photos show that the meter is still running, you have cause to recommend to your clients that they have the plumbing system checked out by a licensed plumber, warning them in advance that the leak is apparently hidden somewhere behind a wall, ceiling or floor, and so was beyond the scope of your home inspection. But take the opportunity to remind them that by performing this extra step--which most home inspectors wouldn't even think of to do--you have been able to notify them about a problem that should be immediately addressed before it would have become an expensive disaster.
While taking these photos is an easy thing to do, this kind of customer service will give your clients some much-appreciated reassurance that you're a straightforward professional who understands his job, such as by being careful to return all fixtures and settings to their original, pre-inspected state. (So, you can also take photos of the thermostat before and after testing the furnace and air-conditioning system.) It also proves that you're the kind of pro who puts his clients' best interests first by confirming either the presence or absence of potential problems in a non-invasive but inventive way.
Providing these photos at the end of your inspection report also teaches your clients a simple home-maintenance tip. By comparing the meter readings for the first few months, they can monitor their family's average water usage, and they can be alerted to any unexpected surges that may indicate a leak in the plumbing system.
Performing this small but important step will also allay some of the anxiety that your clients may be experiencing, and this sort of empathy can translate into positive feedback that you can solicit by giving them a Customer Satisfaction Survey
with your report or with a free copy of Now That You've Had a Home Inspection
. You can then use their positive feedback in your business marketing--on your website and in your brochure. Always remember that marketing on the job is part of the job, and everything you do reflects on your business.
