Just to understand the float switch, it plugs in between pump and electric? Then sensors check high and low level and when water above low level cycles sump pump on? Have utility pump in basement but doing manually, sometimes forget and water gets on...

The controller plugs into an outlet and the sump pump then plugs in to back of the controller. The controller has two sensors on long wires that are placed in the sump pit and attach to the discharge pipe with cable ties. One sensor is attached at the level you want the pump to turn off and the other sensor is attached at the level you want the pump to turn on. The float switch on the sump is tied up in the on position so the pump will always run if plugged into an active outlet. When the water level reaches the upper sensor the outlet on the back of the controller becomes active and the sump pump runs until the water drops below the lower sensor.

Yes, float switch has to reach the top to turn on. The system works best if lowered into a hole in the floot. I dug a hole big enough to lower a 5 gal bucket ( with holes drilled into it). Pump fits perfectly into it. Dont forget a check valve. Luck!

Thankfully I have yet had the pump be activated as it is my backup pump. However, I will recommend that you use the water detecting alarm that lets you know when your electric sump pump has failed because the water level has risen in your pump well. The alarm is recommended at the bottom of the Amazon page when you're looking at the Liberty Pump site. The alarm lets you know you're running on water. If the water pump is running because of a power failure, you can't help it, but if it's a failed pump, then you know to replace it.

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.

This setup works via two probes. One high and one low. When both probes sense continuity to ground (though water) it fires the pump. Pump will run till both probes read no continuity to ground (sump crock empty). It is a good system and worry free.

you need a float switch for auto operation, they are sold separately.this pump will run continuously when connected, water or no water.

Hi, The way have this switch wired up, it breaks the contact when it is no longer upright. I have it connected to a pump which is pumping from a pool, and it floats under the water. When the water level drops low enough, it turns sideways or upside down, current no longer flows to the pump, and the pumping stops. When the pool fills up again, the pump turns on again. So, it is really intended for pumping out a sump, not filling a tank. I looked at the manual on line, at http://s3.pexsupply.com/product_files/RFSN-6,RFSN-9,RFSN-10-User.pdf. I did not see any indication that it can be rewired to work the other way. I hope this helps. Hi, The way have this switch wired up, it breaks the contact when it is no longer upright.

Installed properly, your bilge pump will operate automatically through the switch and also can be turned on manually through your main switch. Personally I had 3 of these electronic float switches and all went bad in 30 days. I prefer the ball floats.

OK the way it works is= it goes in your main water line in parallel and you need a pressure gauge also so you can see what the pressure is and if it says 40-60 what that means is the pump will come on and pump the pressure up in the line with all water flow shut off in your house and it will pump up to 60 lbs and the pump will shut off then wihen you use the water the pressure will start droping and when it gets to 40 lbs the pump will come on and pump up to 60 lbs and the pump will shut off. There are two different kinds of these switches the one I just described and the one that ends in 24M4CP. This one works the same but if the pressure goes below the 40 lbs it dosen't keep pumping it shuts the pump off. You have to manually reset it with the little lever on the switch. The advantage to this one is if you pump your well dry the pressure will go below 40 and the pump will shut off and save your pump from burning up. The bad part is (Like with me, )Our power goes off in the winter a lot in snow storms and if its off long enough to loose pressure I have to walk up in the cold and snow to the well house and manually turn the pump back on. Both of these switches look the same except the on has a little lever sticking out the side of the switch for the reset. You should also have a pressure tank also in parallel with the main line and it works like a capacitor to smooth out the pressure drops. Hope this helps

This float switch is supposed to turn the sum pump on when the water reaches a certain level. The sum pump is to empty the container full of water. But for some reason if there is a lot of water, the float kind of reset it self and then starts again. I think you are looking for another kind of float switch, you know like the one used in toilet tank. ask for a water tank float switch. This float is not for you.

I was wondering the same thing. Seems like it basically just completes the circuit when activated, so I would think you could cut the plug off and wire it in line with the cable from the battery. I don't really want to be the guinea pig that ruins a brand new float switch though.

This pump stays on when connected to DC power. In order for it to come on and off automatically, you need to purchase a float pedal. When water rise's the pump comes on and when the pedal goes down the pump shuts off. They do sell the pumps, with this feature in the pump but it cost a little more.

No it doesn't, I recommend getting the accessory float switch. The switch plugs into an outlet, then the pump plugs into the float switch.

I think all the logic is done in the controller in the plug unit. It arms when either sensor is submerged and activates when the other submerges. The pump then stops when the water level drops below both sensors.

So I put in a backup sump pump (liberty 24v marine battery kind), if my sensors or wiring fail. I mean, your bottom one is submerged in water, so why not the top wiring too. Same diffetence. Get a backup to be safe. Pumps fail. Power fails. Floats and electronic sensors fail. 500 is cheap insurance for a backup system. You can install it, trust me.

Yes...it just has a 110 outlet that you plug your sump pump into. The controller then plugs into the house outlet and then switches power to the pump when the float switch is activated.

T he switch has two positions,man/auto,if you'er pump is not automatic (two wires from pump) use the brown wire.the clear thing is a reset fuse.
