Good engineering and a good product.

This sensor is an example of good engineering both electronically and functionally. It does everything they claim it does with a few extras they don't mention in the advertising. When the water level reaches the first upper limit the pump starts. When the lower level is reached the pump continues for a short time and then stops. If the lower limit sensor fails and does not report a low water level, the pump continues to run for a pre-determined maximum amount of time then shuts off preventing a pump run-on and damage due to running dry. Even if the lower limit fails, the controller will stop the pump based on time and not the actual lower level. The actual sump pumpdown time is measured by the control at initial power up and then doubled as the maximum run time for the pump.

There is a second redundant upper limit sensor that takes over if the first sensor fails to sense the water. The pump will run even if the primary upper limit sensor fails. That's good but they really thought out every scenario. Lets say you get a really hard storm and the influx of water is more than the pump can keep up with. The pump starts but the water level stays near the first upper limit. If it manages to creep below the upper limit the pump will time out and stop. Not good but the pump will restart when the level gets to the upper limit again. Lets say now that, even with the pump running, the water level continues to rise to the second upper limit. When that happens the maximum run time limit is disabled and the pump runs as long as both upper limits are met or exceeded. If the pump has failed there is nothing more the controller could do. If the pump is moving water but not keeping up at least it is pumping something and with luck will eventually catch up.

The Levelguard sensor takes up little room in the sump. It is perfect for small diameter sumps or sumps with backup pumps co-located. Float switches, either vertical or bulb type, need room to work without getting caught or stuck on something. The Levelguard mounts to the pump discharge pipe or other convenient location at any desired level and there are no moving parts, floats or pressure sensors to get clogged, corrode or fail. Water sensing is completely electronic using a field sensing circuit, not conductivity probes that can get dirty and fail.

At just over $100 this sensor is more expensive than a float switch but over the lifetime of the sensor you would use several float switches and had the headache of overfilled sumps or burned up pumps due to dry run. Float switch failure is often in the on state and dry run the pump. The Levelguard sensor will pay for itself if it saves just one expensive pump.

Option for a float switch

Still early but it seems to be well made and is easy to install when you do it while putting a pump in. I've been a plumber for 45 years and I have always thought that the float switch was the weak link on a sewage pump. You get toilet paper that gets on top of the float and wire going to the float preventing it from rising and turning on the pump. This eliminates the float and can be protected from the toilet paper b putting the pump between the sewage inlet and this unit. One thing you should know is it won't work with all pumps. If your pump only has one wire that comes up it won't work with it or if it has a float like the Zoeller pumps have it won't work with that either. Your pump has to have a float that has a separate wire that comes up that the pumps wire plugs into. So far I'm impressed with these.Read full review...

It beats the mechanical float switch

I have gone through several Zoeller pumps, each time due to a float switch failure. I salvaged the old pumps by wiring out the float switch. It works. This thing also lengthens the run interval, which should contribute to the longevity of the pump.Read full review...

good alternative to float level switches

this works just like advertised, only had it for a month but looks like it will last. will buy another for my back up sump. like the no moving parts.
