Filling valve, CERSANIT K99-0012 - vertical bottom inlet

CERSANIT filling valve K99-0012 is a toilet cistern component with a vertical bottom inlet designed to control water supply and maintain the cistern fill level. It is intended for replacement or installation in compatible WC tanks and provides reliable filling operation and stable water flow regulation for domestic and commercial sanitary systems. The vertical bottom inlet design places the water connection at the base of the tank, allowing neat installation in cisterns with lower inlet ports.

Advantages

The filling valve offers consistent fill control and automatic shut-off when the desired water level is reached, reducing the risk of overflow. Its vertical bottom inlet configuration simplifies connection in cisterns designed for lower water entry points and helps maintain compact internal layout. Constructed from materials suitable for contact with potable water, the valve is designed for long-term use under normal operating conditions and compatibility with common toilet cistern geometries.

Suitable for

• Replacement of worn or malfunctioning cistern filling mechanisms in compatible toilets
• New installation in toilets that require a vertical bottom water inlet
• Residential and light commercial bathroom cisterns with matching inlet location
• Maintenance and plumbing repairs where reliable fill control is needed

Key specifications

• Type: cistern filling valve with vertical bottom inlet
• Function: automatic filling and shut-off at preset water level
• Intended use: toilet cisterns with lower/bottom water inlet
• Mounting position: vertical installation inside the cistern
• Materials: water-contact plastics and seals suitable for potable water systems
• Flow control: built-in mechanism for regulating supply until shut-off

How to use

Install the valve into a compatible cistern by securing it at the designated bottom inlet opening and connecting the water supply according to the cistern manufacturer’s instructions. Adjust the float or fill level setting as required to achieve the correct water height in the tank. After installation, operate the flush and observe at least one fill cycle to confirm the valve shuts off at the desired level and that there are no leaks at the connection points.

Usage recommendations

Before installation, verify that the cistern has a bottom inlet compatible with a vertical valve. Turn off the water supply and drain the cistern prior to replacement. Use basic hand tools and replace any worn seals to ensure a watertight connection. If uncertain about compatibility or installation, consult a qualified plumber or refer to the cistern manufacturer’s technical guidance.
