Why Install an Automatic Flush Toilet?

Apart from being stylish and convenient, an automatic flush brings a lot of benefits to your bathroom. Some of the reasons to install this system include:

  • Improves hygiene – The idea of not touching a toilet sounds good. Of course, your bathroom may be clean, but an automatic flush just takes the hygiene to another level.
  • Easier to use – Imagine an older person stretching his hand to reach the handle of a regular toilet. With an automatic flush, people with mobility issues won’t have to struggle to push a flush button or pull a lever.
  • No more forgetting to flush – Training your kids to flush a regular toilet can be hard sometimes. Kids can forget to flush going to the bathroom. An automatic flush eliminates this problem, ensuring you won’t cover your nose while entering your restroom due to a stinking odor.
  • Water-saving – An automatic flush is an excellent investment. This kind of flush consumes fewer gallons of water per flush. Nowadays, manufacturers of automatic flush units provide water-compliant kits, which helps to save water.


How Automatic Flush Toilets Work

The operation of an automatic unit is not far from magic. An automatic flush toilet can sense your presence. Then of course once you remove your butt from its bowl and walk away, it senses a change. As a result, it flushes itself automatically. An automatic flush toilet usually has a sensor, infrared LED detector, and projector that can ‘sense’ when someone is seated.

A microchip signals the LED projector to produce infrared beams at constant intervals. When you sit on the toilet bowl, the infrared light is reflected, and the sensor ‘recognizes’ a presence. Once you are done using the unit and leave, the infrared light does not reflect again, making the sensor activate the flush mechanism to flush waste away.

Here are some potential reasons for automatic toilets to malfunction:

  • Battery life – Automatic flush toilets are battery-powered, and you should regularly replace your sensor batteries.
  • Accumulation of dirt in the sensor – The sensor will likely trap a lot of dust over time. But with regular wiping, you should remove the worry of your sensor gathering dirt.
  • Sensor calibration – Automatic flush toilet rely on infrared light to activate flushing. How the sensor is calibrated will determine the efficiency of flushing. Make sure you follow instructions for setting your sensor calibration to optimum efficiency.
