Typical domestic water consumption is approximately 13 000 gallons per person, per year.

Using the Variflush/ Dual Flush system could save 17.5% of this - over 2 000 gallons per person, per year (or about 100 baths!).

If you are a gardener, compare this with a typical 40 gallon water butt : this could be filled 50 times a year with the savings!

Variflush/ Dual Flush allows you to set the quantity of water used for each flush. To use, just switch to the appropriate setting then flush and walk away.. So much easier to use than other systems where you must wait for the flush to complete before releasing the handle.

These products have been purchased by eight major water companies in the South of England.
