How does a piggyback float switch work?

Electronic float switches will have piggy-back plugs that you plug into the wall outlet. You then plug the pump into the back of the switch plug. There are no moving mechanical parts, but rather an internal sensor that detects the water level. When the switch is triggered, it transfers power to the pump, turning it on.

Can you add a float switch to a sump pump?

Installing a new float level switch will turn a regular sump pump into an automatic one. You simply need to use a float level sensor with two switch points (High and Low) such as the FLE series, and a powered pump relay such as the inexpensive RCU-7000.

Can you bypass float switch on sump pump?

Bypass the circuit on the original float switch and use silicone sealant to thoroughly seal the housing. Loosely attach the replacement switch to the pump housing with a zip tie. Plug the switch into the outlet and plug the bypass plug into the switch. Fill the basin with water.

Can you connect two pumps in series?

Pumps can be arranged and connected in series or parallel to provide additional head or flow rate capacity. When two (or more) pumps are arranged in series they are resulting pump performance curve is obtained by adding their heads at the same flow rate as indicated in the figure below.

How do you run 2 fuel pumps in a series?

For example, take two A1000 fuel pumps “in series”, you know they have the same flow curve (flow the same at any pressure). All we have to do is just divide the desired pressure in half and then check the A1000 flow curve. For example, if we needed 120 PSI, divide by two for 60 PSI.

How do you use a float switch on a water pump?

So there we have it. A two-wire float switch that can easily be used for turning a pump on or off. Mount or suspend your switch at the desired level, get your wires into a water-tight junction box (or out of the liquid containment area and then into a junction box), check the connections back to your control and power equipment, and you’re done.

How does a multi-point float switch work?

In a multi point float switch, a low alarm could trigger the LED light to turn on and send a signal to turn on an automatic water pump to refill the water back to the preprogrammed water level.

How do you control a pump with two normally closed switches?

Let’s start by looking at Control Schematic 3 with two Normally Closed switches. This circuit can be used to control a pump that fills a tank. The first switch (L) is set at the minimum liquid level desired in the tank. The second switch (H) goes at the maximum desired level.

What are the installation scenarios for a normally open float switch?

Installation scenarios might include a Normally Open float switch turning on a pump to empty a tank (Control Schematic 2), or a Normally Closed float switch turning off a pump that fills a tank (Control Schematic 1).
