Two-thirds of the water used in an average home is used in the bathroom. A lot of water may be going to the sewer needlessly, adding to the volume of sewage and putting an extra burden on treatment plants. Every time a toilet is flushed, about seven gallons of water goes into the sewer. Toilets should not be used as trash cans to flush away tissues, gum wrappers, cigarette butts, spiders, diapers or anything else that ought to go in the wastebasket or garbage can. All of us do it at one time or another, but use of the toilet as a wastebasket is just a phenomenal waste of water.
Most toilets use more water than is really necessary and work just as well with less.
The extra weight might crack your tank. Besides, the bricks may begin to disintegrate after a while, causing serious and expensive problems in the plumbing. Use a plastic soap or laundry bottle instead. It s safe, easy and inexpensive. Fill a few bottles with water to weight them and put them in the tank.
