ES4000 Back to wall
ES4001 Wall mounted
The ES4 integrates a high-performance siphon cistern, innovative water-saving inlet valve and high quality Swedish pan.
ES4 is WRAS approved and is already installed in a wide range of domestic and high profile commercial projects.
The ES4 is a qualified product on the Water Technology List, a Government scheme which offers tax relief for businesses investing in sustainable water technologies.
The flushing mechanism
WCs which use valve flush mechanisms are inherently prone to leakage. Valves demand skilful and prompt maintenance to remain efficient and require specialist parts often unfamiliar to UK plumbers.
In contrast, the ES4's award winning Thomas Dudley Turbo siphon is leak-free and has been tested to over 1 million cycles without failure. The robust two-part siphon is reliable and easy to maintain, which means the ES4 can be relied on to remain efficient, year after year.
The inlet valve
The inlet valve in most WCs wastes water by allowing the cistern to start refilling during the flush. The ES4 features a virtually silent delayed-action inlet valve, which saves water by preventing the cistern refilling until the flush is finished.
The pan
The ES4's high quality ceramic pan is the key to its exceptional performance. Produced by Swedish manufacturer Ifo Sanitar AB, the pan is precisely engineered to operate effectively with an ultra-low volume flush. It is available in white ceramic, either back-to-wall or wall-mounted.
Siphon and valve flush mechanisms
The siphon flush mechanism is, by design, leak-free. It is robust, requires little maintenance and is familiar to all UK plumbers.
In contrast even the best valve flush mechanisms need to be carefully commissioned to ensure efficient functioning, and monitored to ensure that they do not jam or leak. Spare parts are less readily available in the UK, and the mechanisms less familiar to UK plumbers.
In comparison with the most efficient approved valve dual flush WC (6/3 litres), ES4 can be expected to operate with better overall water efficiency.
