A regulating device for regulating water consumption of a concealed water tank includes a water tank, a hinged base is fixedly arranged on the inner wall of the water tank, a water separator is hinged on the hinged base. A regulating mechanism is arranged between the hinged base and the water separator, and the regulating mechanism can drive the water separator to rotate and fix to divide the accommodation space of the water tank. Compared with the prior art, the regulating device realizes the variable volume of the water tank by regulating the rotation of the water separator through the regulating mechanism. The structure is simple and convenient for the later repair and maintenance of the water tank.

A controller acquires image data captured by a camera which is located at a toilet to capture an image of a bowl of the toilet, determines whether an unacceptable matter being an object having a possibility of clogging the toilet is in the bowl by performing image recognition based on the image data, and sends, to a flush water controller, a flow prohibition signal of prohibiting flush water from flowing when it is determined that the unacceptable matter is in the bowl.

The system includes a fluid valve with a modular and/or replaceable fluid control assembly that requires maintenance over a product life of the fluid valve. The modular and/or replaceable fluid control assembly includes at least one portion including a setting or presetting configured and arranged to control fluid flow behavior in the fluid valve. The setting or presetting is useable to control fluid flow in the modular and/or replaceable fluid control assembly after an upgrade or replacement of at least a portion of the modular and/or replaceable fluid control assembly. Further, the setting or presetting enables the modular and/or replaceable fluid control assembly to retain the fluid flow behavior following one or more upgrades or replacements of one or more portions of the modular and/or replaceable fluid control assembly.

A water-saving accessory for a toilet includes a basin, a three-port valve, and first and second lengths of tubing. The basin has inlet and outlet ports and is configured to be coupled to the toilet bowl or toilet seat. The valve is configured to be coupled to a fluid supply line. The first length of tubing is configured to be attached at a first end to the valve and at a second end to the basin inlet port. The second length of tubing is configured to be attached at a first end to the basin outlet port. The valve can be configured to be coupled to a flush line for the toilet bowl such that fluid is normally supplied from the fluid supply line to the flush line, and to be actuatable to divert fluid from the fluid supply line to the first length of tubing.
