Automatic Bathroom fixtures (sensors) 1

[Couplandboy]

I have a relatively remote and unmanned facility with a restroom that includes a sink and toilet. I think having these fixtures equipped with optical sensors was a result of our trying to incorporate LEED principles.

My concern is that our facility will be served with a small septic system. I've walked into restrooms on more that one occasion and seen automatic fixtures stuck and running. If that happens it could go undiscovered for some time and the septic system will be overwhelmed. Is this stuck/running condition highly unusual? Is this a statistically unfair characterization of these fixtures?

It sounds like the sensor beam(s)need to be adjusted. They might be reflecting off the opposite wall or some other obstruction - so it thinks there is something there. Adjust the sensor beam and the problem will go away.

Some automatic faucets also have a timer which prevents long run time. This is often to prevent vandalism (flooding the sink). Check that also.

Clarification - the station is currently under construction. I'm trying to decide between staying with the sensored fixtures or going with manual operation. Personally, I see no reason to go with the sensors.

My question is simply whether or not sensored fixtures are prone to being stuck open and whethe that is just a misconception on my part.

If the sensor is set up correctly prior to occupancy, you should not have inherent issues with sensor fixtures.

I've seen a lot of leaky faucets. Not very many of the sensorless ones, but then, they are new-ish. Any valve seal can develop a leak.

It is a well established water conservation measure to install automatic sensors.

Consider the result should an individual leave the water running in an unsupervised restroom.

Note that automatic sensors for flush fixtures DO NOT improve water use – they simply ensure that those fixtures are flushed. Automatic sensors for flow fixtures on the other hand allow for a reduced duration of use, thereby reducing the amount of water used.

Your contract should include a 1 year warranty period to ensure that the plumbing fixtures are properly installed.
