Everyone has a toilet in their home. In fact, you probably have more than one. And you probably do not give much thought to the type of toilet you have. After all, a toilet is a toilet, right? Well, there are actually several different types of toilets, and while they all get the basic job done, there are reasons to favor one type over another.

One such distinction falls on what are known as high-efficiency toilets. These toilets use significantly less water than standard toilets on each flush, thereby saving you money on your water bill every time you use them. No toilet on the market today is permitted by law to use more than 3.5 gallons of water per flush. High-efficiency toilets, by contrast, generally use between 1.6 gallons and 1.1 gallons.

That might not seem like a huge difference, but just think about how many times in a day someone flushes the toilets in your home. That will add up fast. Installing a high-efficiency toilet can save you as much as 12,000 gallons of water a year. And depending on the size of your household and the number of toilets you have, that figure could be even higher.

Of course, a lot of people shy away from high-efficiency toilets because they are concerned about performance. It seems unlikely to them that a toilet that uses so much less water could work effectively all of the time. The truth is, though, that many high efficiency toilets work even better than conventional ones at clearing the bowl in one flush. And high efficiency toilets do not clog any more than regular toilets. In fact, they often do better in that area as well.

Another thing to bear in mind is that toilets last for a long time. This means that the toilet in your home could be quite old. Toilets made before 1980 use much more than modern toilets are allowed to use per flush. Some of them actually go through five gallons or more of water each time you use them. By replacing an older toilet with a new, high-efficiency model, you will be setting yourself up for some significant savings on your water bill each month.

Your toilet is not an overly complicated piece of equipment. But in order to work properly, it does require that all of its parts are in the right place and in good shape. Even if something small on your toilet is out of place, it can cause problems like constant dripping or running, improper flushing force or a sudden refilling of the bowl when no one has flushed the toilet.

These problems can sound serious, but many of them are quite easy to address if you know where to look. With most toilets, that place is the flapper valve. The flapper valve is a relatively small rubber plug that fits over an opening at the bottom of your toilet tank. When you press the handle to flush your toilet, the flapper valve lifts up and allows all of the water from the tank to go rushing into the bowl.

The force of this water pushes everything out of the bowl through the drain at the bottom, clearing the bowl and refilling it with fresh water all at once. As long as the flapper valve is able to maintain a tight seal, this process will go along smoothly without a hitch. But sometimes these valves become dirty or simply wear out.

When that happens, water can begin to leak down from the tank into the bowl on an almost constant basis. Depending on the severity of the leak, this may just cause the toilet to run constantly. Or it can even cause periodic “phantom flushes” were the toilet clears the bowl without anyone pressing the handle.

Phantom flushes occur because too much water has seeped down from the tank into the bowl. When the volume in the toilet bowl reaches a certain level, the water in the bowl is forced out, resulting in a flush. This wastes water and can also be pretty startling if you are not expecting it. Fortunately, though, you can usually fix this problem easily enough.

To do this, check your flapper valve to make sure it is keeping a tight seal with the bottom of the tank when not in use. If it is not, you may only need to clean it off to restore the integrity of the seal. In more serious situations, however, you may need to replace the flapper valve entirely. This is not difficult or expensive and can save you a lot of water in the long run.
