Does this pump automatically turn on if water hits it, or does it run continuously when connected to the battery? thanks

I have mine on a switch, it is not an automatic on/off water activated pump.

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

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.

The pump has to be running to use it . Once the pump is off..it goes flat, but pumps back up in seconds when pump is on.

This pump has the electrical incorporated in to the top cover. The float is pre-wired, so all you do is plug it into an 120 VAC common household outlet. The outlet should be 120 VAC rated at 20 amps at the breaker. The service disconnect is you unplugging the pump. This pump will run when the float is lifted up by the water level in the receiver tank. The pump running stops when the water level allows the float to flop down (as seen in the illustration at Amazon). Hope this answers your question - Mike

The pump will start working automatically when the level of the water is approx 8" and stop at 4".Other pumps may be better for you. I use mine under my house in a hole that I dug.

Yes, it simply turns the power on and off, but not all pumps are meant to be started frequently. I have good experience with Hydor, bad experience with cheap pumps.

I thought the same thing, but I assume the pump has a pressure-sensitive internal by-pass valve that simply recirculates the water inside the pump until called upon to pump water into the water line. That's the way most constant run pumps work. I've had mine connected for over a year now, and it's worked great. What's amazed me more than anything is that you can't hear the pump running. It's so quiet, you actually have to feel it to verify that it's running, and even then there's so little vibration, you almost can't feel it.

The pump is electric. You plug it in and it automatically turns on and starts pumping when you "lock/secure" the pump on the bed. No need to charge the pump. No batteries involved. It's amazing.

The on off switch is inside the float..... If the float is not floating in a vertical position it will allow pump to run. When water level is low and float is at bottom of tank (or other water holder.) The foat asit touches bottom will fall into a horizontal position and the switch in the float will stop pump from running.......this is true if float switch is wired correcty to the pump. I belive a diagram coms with the float package. v.

My setup is a T connector added to the outlet side of the pump. One end of the T runs to the pressure tank, while the other end connects to the house main water line.The best part is this pump has a built-in pressure switch, so it turns on and off only when the pressure is low on the tank.

The pump always runs off of battery power; however, if the main pump fails, and the power is still on, the battery is still constantly charging. So, the pump can run LONG periods of time, because the battery is always receiving a charge.

The pump will run all the time during the time you have it set to cut in. Not just when the water is cold.

It turns off automatically. I turn it in just before I go to bed and fall asleep to the atom and it goes off by itself when the water is evaporated.

This pump primes itself when switched on ; then only runs if you trigger the sprayer wand. I've had no trouble with mine after spraying pesticides and weed killer.

This pump does have an automatic switch that works based on the water level. (I can't answer about the discharge head height.)

As far as I can tell it only has to option to run on C batteries. I remove the batteries when the pump is not in use, in an attempt to prevent the batteries from draining too quickly.

You half to hook the yellow wire straight to battery it is the memory wire for it ifyou have automatic bildge it work just like it when you turn the batteries off it still should run and pump the boat out

It automatically turns on and makes sure it can pump the water out. I think it does it monthly or twice a month.
