If you have an old toilet in your home, you’re using more water than you need to be (and that means you’re spending more money on water bills than needed). While toilet water use varies, older toilets (built in the mid-90s or before) typically use 3.5 gallons per flush (gpf). Nowadays, new toilets use 1.6 gpf (or less). Toilets considered as "high-efficiency" or "HET" use 1.28gpf or less. If you (just one person) flush your toilet an average of 5 times per day, your older toilet could be flushing 10,439 gallons extra down the toilet (literally) per year than a newer toilet would. Multiply that number by the number of people in your household for a more shocking number.
There’s much to gain by increasing the efficiency of your toilets. You can help the environment and you can also save some cash by reducing your water bill. Below are some solutions worth considering when it comes to your toilet flushing systems:
Single Flush Solutions
While a single flush toilet may look like your old inefficient toilet, times have changed things for the better. In 1992, the Energy Policy Act law made 1.6 gpf a mandatory federal maximum for new toilets. While the first round of efficiency toilets didn’t get raving reviews with regards to their flushing power, technology has advanced with the times, and many models are using even less water now with powerful flushes. Here are a few single-flush options we recommend:
- TOTO’s Double Cyclone® Flushing System – which has a dual-nozzle water propulsion system for more efficient powerful flushes at 1.28gpf, and a hole-free rim design promoting less bacteria growth.
- TOTO’s E-Max® Flushing System – combines the extra-large siphon jet with a large glazed trapway for incredible flushing force, but still only uses 1.28gpf.
- STERLING® PRO FORCE® - available in standard 1.6gpf models and 1.28 HET models.
- Mansfield MagnaFlushII™ Maverick - a HET option with 1.28gpf flush and an extra-large 3" flush valve that boasts more than twice the potential flushing volume as a standard two-inch flush valve.
Dual Flush Solutions
Most toilet manufacturers today offer this newer solution which allows you to choose the amount of water that accompanies your flush (with two button options). Here are some recommended dual flush options:
- TOTO’s Dual-Max® flushing system uses .9gpf for the smaller flush and 1.6gpf when more is needed.
- STERLING Dual Force® technology, which gives you the choice of the 1.6gpf button or the .8gpf button.
- Mansfield’s EcoQuantum toilets, a single lever which you can either lift upward for a strong flush, or push down for a high-efficient flush
