## Long description

Sourcing DOUBLE WATER FLUSH MECHANISM 136.919.21.2 is a dual-flush cistern mechanism designed to control two distinct flush volumes in compatible toilet tanks. Intended as a replacement or spare part, the unit provides separate actuation for full and reduced flushes, enabling water-saving operation without altering the existing cistern shell. The mechanism connects to standard tank fittings and is engineered for straightforward installation and routine maintenance in both residential and commercial bathrooms.
Advantages
The dual-flush design supports selective water use for liquid and solid waste, reducing overall water consumption. The mechanism is compatible with common cistern layouts and uses standard plumbing connections for simple replacement. Built for durability and ease of maintenance, it allows servicing of moving parts without removing the entire cistern. The separate actuation improves user control and helps meet water-efficiency requirements in buildings.
Suitable for
 Replacement of worn or malfunctioning dual-flush mechanisms in compatible toilet cisterns
 Retrofit projects aimed at reducing household or facility water consumption
 Residential bathrooms and light-commercial washrooms where dual-flush operation is required
Key specifications
 Function: dual-flush mechanism with two separate actuation options (full and reduced flush)
 Compatibility: designed for use with standard toilet cistern fittings and mounts
 Installation: top or front actuator connection depending on cistern design (check tank configuration)
 Materials: corrosion-resistant plastics for internal moving parts and seals suitable for potable water
 Maintenance: serviceable components allowing part-level replacement without full cistern removal
How to use
Shut off the water supply and drain the cistern before removing the old mechanism. Fit the Sourcing dual-flush mechanism into the cistern according to the tank orientation and secure it to the existing mounting points. Connect the actuator rod or button assembly to the mechanism, restore the water supply and allow the cistern to refill. Test both reduced and full flush functions and adjust the float or water level as needed to achieve the desired flush volumes and reliable operation.
Usage recommendations
For reliable performance, confirm cistern compatibility before purchase and replace worn seals during installation. Periodic inspection and cleaning of the valve seat and moving parts will extend service life. If unsure about fit or plumbing connections, consult a qualified plumber to ensure proper installation and water-tight operation.
