Electronic Plumbing

In public facilities, the trend is toward sensor-operated fixtures that improve hygiene and save money. For example, sensor operated automatic-flush urinals have fewer moving parts, reduce wear, and tend to last longer than manual-flush valves. Also they ensure fixtures are flushed only once per use. Some contain intelligence that flushes them at different amounts of water flow depending on traffic patterns: e.g., the fixture can detect a lineup of users and only give a full flush after the last person has used the urinal.

Automatic flush compensates for users who do not bother to flush. Also, since the fixtures are always flushed, there is no need for a urinal cake, or other odor reduction. Sensor-operated toilets also have automatic flush. Sensor-operated faucets and showers save water. For example, while a user is lathering up with soap, the fixture shuts off and then resumes when the user needs it to. Sensor-operated soap and shampoo dispensers reduce waste and spills that might otherwise represent a slippage hazard.

However, many people, especially children, dislike or even fear automatic flush toilets, since they have the tendency to flush without warning, even while the user is still sitting on the toilet. Some parents have started keeping track of public bathrooms that have manual flush toilets, or even carrying post-it notes or other devices with them to temporarily disable the automatic flush sensor.

These fixtures typically cost more to install than conventional plumbing fixtures, because thy require the services (or presence) of both a licensed plumber and a licensed electrician. Construction companies on cost-plus contracts may actually favor these fixtures for this reason, although their clients may not. The additional complexity of these fixtures also complicates repairs, particularly the diagnosis of malfunctions causing unexpected flushing. Few electricians, and fewer plumbers, understand microelectronics well enough for complex diagnosis.
