My grandmother was a penny-pincher of the highest order, and she passed down all sorts of tricks that my family still swears by to this day.
But her simplest tricks were the best, and this was my all-time favorite.
If you're like me, you probably notice your water bill creeping up from month to month.
You know your family probably isn't using more water than usual, so what explains the extra costs?
Often, your toilet tank is leaking down into your bowl.
That may not sound like a big problem, but every drip is like a fraction of a cent on your water bill, and it adds up.
NYC Environmental Protection says a small leak can cost 40 cents a day, while larger ones have been known to hit $53 a day.
So how can you check if your tank is leaking?
The Color of Money
Take some food coloring from your kitchen and put a few drops in your tank, just enough to noticeably change the color.
Don't flush the tank for the next 15 minutes. You can drip coloring in another tank at the same time, to check multiple toilets.
When the time is up, if your toilet bowl has changed color, you definitely have a leaky tank.
Next, you'll have to fix it.
