CISTERN LESS FLUSH WC 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:
- No more 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 with 30-year warranties.
- Labour costs are reduced as less servicing is required to repair leaks or carry out maintenance.

Many retirement homes, care facilities, 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.
The retirement home in the example below replaced 300 standard cistern-fed toilets with DELABIE'S cistern-less flush
systems. In addition to the elevated water consumption, the previous installation required:
- changing the mechanisms every 3 years
- 2 hours of maintenance per day to repair leaking cisterns.
