Q: We’ve read your columns on water-saving toilets and want to replace our old master bedroom toilet. Since this is our private bathroom, we want a new toilet that will be efficient and fit our lifestyle. Are dual-flushing toilets considered high-efficiency toilets? We are looking to save water but want to choose our own flushing options.

A: Installing a new high efficiency toilet is one of the best ways to start saving water in your home. Standard toilets are rated at 1.6 gallons per flush, while a high efficiency toilet is rated about 1.28 gpf or lower.
The reason dual-flush toilets can be a popular choice is because they can deliver a full standard flush when needed. But, if you’re basically flushing liquids, a second flushing option is available at about 1 gpf.
Never miss a local story.
In most cases, when you average in the amount of highly efficient water-saving flushes used, a dual-flush toilet can qualify as a high efficiency toilet. That is good news for anyone looking for a high efficiency toilet where you can choose your flushing options.
Speaking of flushing, some dual-flush toilets use buttons; others use a special lever, so you may have to duel over the flushing style of your new high efficiency toilet .
