Install a High Efficiency Toilet
Toilet flushing can account for up to 30 percent of household water use. Save up to 65 percent of this water by installing a high efficiency or dual flush toilet. High efficiency toilets use 4.8L of water or less per flush. Typical dual flush toilets use either 3L or 6L per flush. All Eco Options approved toilets meet this high efficiency standard.
You'll install a new high efficiency toilet in two steps - first the bowl, then the tank. The most difficult part of the installation will be putting the bowl in place. It's heavy, and you'll have to place it so the floor bolts are directly lined up with the holes in the toilet base. When working with heavy porcelain items such as toilets, avoid banging them into anything. Porcelain is tough - up to a point. If it cracks, it can't be used.
