Saturdays at Home: Toilet Brick

So, next time you hear someone proclaim they're going to drop a brick in their toilet, congratulate them. Why? The old folk wisdom that says place a brick in your toilet's water tank is partially correct: It's an effortless way to save water, but a brick isn't the best choice of object. Use a plastic bottle filled with water instead.

Don't worry, you don't have to turn hippie and "let it mellow if it's yellow" in order to save clean water — which is an increasingly scarce resource. Most toilets will flush perfectly well with a little less H2O. The average model uses three to seven gallons per flush. A bottle in the tank will displace enough water to save half a gallon to a gallon each use, or up to about 10 gallons a day in a typical home.

All you have to do is drop a little sand or some pebbles into a bottle, fill it with water, and put it in the tank, making sure not to disturb the toilet's working parts.

What's wrong with a brick? They have been known to disintegrate in toilet water over time, leading to damaged plumbing. If you are a mason or otherwise determined to use a brick, wrap it in a sturdy plastic bag first. Interestingly, some utilities in Europe give away special sachets, called Save-A-Flush, which were specifically designed to displace water in toilet tanks.


For a little more effort, use old jelly jars.... barely any effort....
This literally could not be easier. Fill jars with water. Set jar in tank. Forget about it forever. The only catch is to make sure the labels are off the jars. You don't want them to come off and float around in the tank -- they might interfere with the flushing mechanism.

Savings:
Two cups of water per flush and I'd say we're now averaging eight flushes per day. So 8 x 2 = 16 cups per day, or one gallon. In one week, that's seven gallons of water. In a year, 365 gallons saved! That shaves another percentage point off my riot numbers! Woo!
