What’s new on Winner® S flush cisterns: keep an eye on the label

The Winner S in-wall flush cisterns have been awarded the Best WELL rating for water saving: a useful help for plumbers, designers, architects and all customers in choosing the right WC flush system.

Greater water efficiency, without altering the performance

Drinking water: a resource threatened with exhaustion. In Europe, due to climate change and irregular nature of outflows, in certain periods of the year the total amount of water available decreases and can not meet the daily needs of all people. An increase in the demand of drinking water produces a rise in expenditure for water treatment and transportation and an increase in the energy needed to heat water.

Regarding the ecological strategy ongoing in the plumbing and heating sector, EUnited Valves (the association that represents the main European valve producers) has developed a new European classification system: WELL - Water Efficiency Labelling. Thanks to the WELL rating, the efficiency in terms of energy saving of the WC flush systems are immediately assessed by designers, architects, plumbers and end users.

It is important to know that the pre-condition to obtain the WELL certification is passing a strict approval process - in accordance with DIN EN 14055 and DIN 4109. The tests are performed in an accredited ISO 17025 laboratory only in the case of products with noise levels not exceeding 20 dB (A) with a pressure of 3 bars and noise levels not exceeding 25 dB (A) and a pressure of 5 bar (Class I). The test laboratory is the TÜV LGA which, following the approval assignment, carries out annual audits and inspections on the product, therefore in compliance with WELL requirements.

How to read the WELL label of water saving and make the right choice

According to ISTAT, about 30% of the water consumption used in an average family goes away for flushing toilet (ISTAT, 2005). You can save a lot by implementing virtuous behaviors without compromising the functionality of the wc system. If we consider that a four-member household discharges the flushing toilet at least 12 times per day, the consumption of drinking water can be reduced by 68% using a 4-litre double flush cistern, using the minimum volume of water, as shown in the following table:

Example of potential water-saving

Water consumption for a 9-litre flush cistern:
12 x 9 l = 108 l/day
Water consumption for a 4-litre double flush cistern:
5 x 4 l = 20 l/day
7 x 2 l = 14 l/day
Water saving 74 l/day

For the purposes of the WELL classification and the assignment of related points, it is considered the unit of system composed by the flush cistern and the push plate. In this way, the single flush cisterns (without points for classification) can be equipped with a push plate and start/stop function (1 star) or double flushing (2 stars). With the latter, a saving rinsing is carried out that puts into circulation the exact amount of water needed for the cleaning activity.
