I have a 6000 gal pond/water feature - I assume with the vertical float it will descend and turn off when the water lever reduces.

Yes. The float will turn it off and on, but you must make sure you do not submerge the power plug.
1433312
Yep. It will shut off when the water gets down to about 2 inches. However, I am not sure that this unit is designed for continuous duty that a water feature would demand. It's typically used in a sump pit and cycles on/off as the pit fills and then is pumped out, repeat, repeat...

When the water level raises enough for the float to raise the top lever/switch , it will turn on & pump the water out of your sump. When the water level is lowered to the bottom the float descends on the rod turning the pump off. It has been a great pump. Water level up pump on, water level down pump off. Thanks B.B.

I would agree with the answer I read that this unit is meant for a sump. One thing that is recommended is that the switch be replaced every two years or so. I had two of these and had to replace the switch after about three years of winter/spring use. Not used in summer/fall.

The pump is activated when the float rises due to water rising about 6-8 inches above the pump base

I tested mine and it will pump vertically for at least 6 feet without a problem.

it floats if dropped unless it is not propely closed in wich case it sinks by the water inside the battery compartment. As an hydrodynamic device it works a lot better underwater so in a swin area will work fine if the lake is quiet with not noticeable stream. Believe me, at half sinking works poorly but when you pun under water level it is really nice.

Manual is not clear where it should sit...but if it does float above water until water low....mine does not turn off.

There is always going to be some water left in the pit roughly 4" inches. That is so the pump doesn't run itself dry. If you want to get the water level lower try adjusting the float position.

The float acts as a switch. As the tank fills, the switch on the float is turned on to drain the sump tank!

I hope you added it. Although it's good to pump it around I think it will be good for the pond. I also shut my pump down for the winter I run an aireator through the winter to keep hole in ice for gas release. I'm sure that moves the water around also. Good luck.

Yes. There is a float mechanism in the bottom of the resevoir which shuts the unit off when water is low

This is probably not the best choice. For each 33' of head (vertical lift of water plus restrictions in discharge line) the pump will have to overcome ~15PSI (14.7). The pump has ~ 55 PSI. Additionally these diaphragm pumps don't like any trash that may be sucked up from the lake water. Even if you put a filter, the restriction on the suction side may be too much to overcome. Technically speaking the pump should do it, but it is probably not the best choice. Additionally the pump is for intermittent use, so if you plan on pumping for a while the pump will overheat and shut off. - Good Luck

Maybe it's because you just turned it on. If you just turn it on high it will drop down to a lower speed until the water circulates and then go back up. It takes about 5 minutes.

No: The float will start when it is at the top of the pump. Probably about 6"

Yes it has a little sensor that shuts off the unit when the water level falls below it.

It works like a valve, when the water level goes down it closes by power of the skimmer suction in order to let the main drain start suctioning without air going inside the pump.

The float raises a rod that makes a switch on the top cover when the water level is high enough. The Float moves up but only slightly. Sometimes it can get misaligned and not work properly. If you have filled it with water and it doesn't run push down on the top cover on the right side. If the unit comes on then the rod is not moving up and down properly. For those of you whose units do not shut off when empty also check the alignment of the rod and make sure it moves freely.

Yes. Just make sure the suction lines have no air leaks. It will actually pull up hill about 20 feet if the suction line is sealed. You also need to put a foot valve on the suction line so that when it shuts off the suction line keeps water in it.

I suspect not. But let me remember to measure what I still have left unused. A hint might helpful to you - the device is designed permanently open and when backup happens, the float will be lifted and close. I found during the whole time when there is no backup, which is true for maybe the life of the device, it'll collect all kinds of debris so it can't really close tightly when it needs to. What I did was adding a spring to the top of the shaft connected to the float and make it permanently close. In case you have water on the floor to drain, just push the float down to drain it. But anyway, I'll come back to you about the size. I suspect not. But let me remember to measure what I still have left unused.
