              DIRECT FLUSH SYSTEMS:
              A RAPID RETURN ON INVESTMENT



              WCs with cisterns are still often installed in public places, in particular, because the initial investment may seem lower. However, the initial
              saving ultimately turns out to be very costly, very quickly.

              The many advantages of the WC direct flush system - improved hygiene, fewer leaks, water savings, reduced maintenance
              and easy servicing - very quickly make the product better value.

              By switching to a direct flush system, gains can be made on several levels:
                 - Fewer water leaks (which can reach 220m³ per year per WC).
                 - Fewer maintenance interventions: there are multiple components that need to be changed regularly on cistern-flush systems
                    such as: fragile mechanisms which cannot withstand scale, control plates that break since they are not designed for intensive use
                    or vandalism, etc.
                    Direct flush valves are equipped with scale and shock-resistant mechanisms, which are guaranteed for 30 years.
                 - Less labour is required to repair leaks or carry out maintenance.

              Many retirement homes, care facilities, student accommodation, etc. are currently fitted with cistern-flush WCs,
              because these facilities are associated with a residential setting.
              However, even if the users are resident for long periods, they are still public buildings with the same needs as any other public building:
              water savings, resistance to frequent use, easy to install and maintain, etc.

              Example: a retirement home with 300 beds.

              With cistern-flush WCs installed:
                 - Mechanisms require changing every 3 years
                 - 2 hours of maintenance required per day to repair leaking cisterns.
