Push flush vs lever operated toilets
Traditionally, toilets have been flushed using a lever type handle. Modern technology, however, has resulted in far more efficient flushing systems, and consequently, the push and dual flush cistern. For those with traditional tastes, the lever flush offers not only appeal but that traditional design you require. The push flush is becoming far more common nowadays though and has taken the industry by storm.
Working on the basis that when the lever is pulled down it allows the cistern to be flushed and filled with the aid of a ball valve, the lever does have its disadvantages: it can be inefficient and high maintenance. Some do see this as the best form of flush though, due to its simple design and traditional appeal. Available in a number of styles from chrome to ceramic, the lever flush toilet is primarily seen on the close coupled toilet. It wouldn’t be uncommon for these to be found on older style concealed cisterns though.
We have all experienced the results or a poorly flushed lever type toilet, so the introduction of the push flush cistern, common with the majority of toilets nowadays, is a relief. Its simple design, efficiency and dual flush capability allow for a far superior flush and style. Generally located in the centre of the lid on close couple toilets or as a button or plate on concealed cisterns, they offer minimalist design with a highly effective flush, available in a number of styles and finishes.
The flush can be pneumatic or mechanically operated: a pneumatic button works on the basis that air is forced down a small hose once the button is pushed, which then activates the flush; the mechanical type uses a rod so that when the button is pushed, this engages with the cistern, which in turn flushes the cistern.
Dual flush operation
With an ever increasing trend towards water conservation, the dual flush toilet allows the user the option of a part or full flush. Only found with push flush operations, the buttons, when specified as dual flush, will incorporate a split design to distinguish a part or full flush (commonly 3ltr and 6ltr flushes).
