In box
Additional equipment included in the delivery of the urinal, in addition to the bowl itself.
—
Cover. Cover that closes the bowl. See more about this function. «Installation of the cover», here we note that buying such a kit is usually more convenient than searching for a cover separately.
—
Drain mechanism. The device that provides water descent. It usually includes a nozzle, which is responsible for the optimal distribution of water in the bowl, fittings for connection to the water supply and a drain control system. The control system can be different: the simplest variant provides a valve, lever or button to open-close the water manually, and in models with automatic drain sensors and electronic circuits are used (see more. above).
—
Siphon. The presence of a siphon supply kit is a characteristic curved pipe for drainage. This package eliminates the need to buy a siphon separately, especially since the complete pipe is optimally suited to the urinal in size. However, it is not impossible to specify the size of the complete siphon and check how it will fit into the intended installation site.
Power source
The type of power used in a urinal with electronic components — for example, for automatic flushing.
— Batteries. The main advantage of such urinals is ease of installation — they do not require electricity supply from the network, which eliminates the difficulties of laying wires. However the operating time on one set of batteries is limited, and replaceable batteries usually have to be purchased separately. On the other hand, the electronic components of urinals are usually not particularly “gluttonous” in terms of energy consumption, so that the battery life period is often calculated not even in months, but in years.
— Network. Mains power is convenient because the user does not need to monitor the condition of the batteries and periodically change them — the electronics will work as long as there is voltage. The downside of these amenities is, first of all, some complexity in installation: you need not only to install a urinal, but also to make wiring. The second nuance is that when the electricity is turned off, the urinal can become completely useless.
In general, this option is especially convenient for plumbing used in public places — for example, toilets of train stations, shopping centers, etc.
— Network / batteries. Urinals capable of using both types of supply described above. Usually, in such devices, the main source of energy is the mains, and batteries are used as a backup option in case of power outages.
— Battery.../ generator. Quite an original option: a combination of a generator driven by a stream of water and a battery. In this case, the battery is the direct power source for the urinal electronics, while the generator is used to recharge it as needed. Thus, the power supply is completely autonomous, independent of the mains; and additional maintenance for such devices is practically not required (unlike the same battery-powered models — see above).
