Will the pump only come on when it senses water? I want to use it in a window well that is dry unless we get a very heavy rain.

Yes, you are right. It has water sensors. If there is no water to touch the sensors, the pump will not start. Thanks for your interest.

I actually purchased the pump for the same reason! While plugged in, the pump doesn't engage until about an inch and a half of water is surrounding the pump. Once it does, it reduced the water level to less than half an inch.

It turns on automatically when it senses water & shuts off when the water is down to an inch or less. This was the only pump we found in this price range w/ the automatic start/stop feature. I use it for draining excess water in my pool & it has worked well.

It hasn't happened to me, but I would guess that the pump will continue to run "dry". Probably not a big deal for short periods of time, but could accelerate the wear on the pump.

You need to look at the various pumps offered. I guffed the first purchase and got one without a shutoff. I sold it to a friend and got another which specific addy showed a round bulb that is tethered to the pump and floats according to the water level it will turn on or off. The picture will tell all. This app read NOT to have a shutoff.

The pump does not have an on/off switch. We have it on a timer connected through the computer software.

pump comes on quickly when water is turned on and pressure is pretty quick. The pump is in the garage but I can hear it hum if I listen close enough.

When the water hits a height over the pump the pump turns on. I didn't have good luck with this pump. It stop working correctly with 6 months

Correct. When the water level hits the highest sensor the pump starts running. When the water level fall to the lowest sensor, the pump shuts off.

I'm not sure how to answer this question. On my dehumidifier, when you put the unit in "pump" mode, it stays in pump mode. The only time water goes into my tank, is when I do not turn the pump button on, so I'm not sure why yours is changing from one function to the other. In fact, where I use mine, it is so humid, I never even attempt to use the tank feature. Sorry I couldn't help you more. randy

No, it is either on and pumping or off when power is disconnected. Unless you have a way to turn the power on and off from water level then it is on all the time.

That what it is made for. Hang the unit on the guther where it is free of hose, sprinkler water. When it rains it fills up a bit and shuts off the valves of your pump. Grat unt as we are often away . Works perfect! Jack Krielen

We had bad luck with this pump, it doesn't work very well if it rains hard it doesn't work at all. We have to press on it by hand to make it operate. We use it for our boat.

Yes the pump does have a float sensor that only turns on when the pump fills with water.

This pump is normally submersed in water, like a sump pump, so this question does not make sense. Operating it dry could be expected to quickly burn it out. It was not designed to pump very hot water either.

You are not going to want it to pump until it is completely dry, but you can adjust the off float to remove the majority of the fluid. So to answer your question yes it is normal to have some water left. Depending on your application you may have more or less then other people due to how much lift your pump must overcome. Let us say you are using it in a basement. the pump pushes the water up the pipe until the water level hits the cutoff point. If you did not install a back flow inhibitor, gravity would drain the pipes back into your tank causing it to look like it cut off with a good amount of water in it, but less than the cut on float. hope that helps.

Mine only comes on when water flows through it. Works perfect. I love this system.
