Types of Float Switches

Whenever you are looking to replace your sump pump float switch, you should first understand that there are four main types. Each type has its characteristics, and this means you should find one that is ideal for a particular type of installation. In this section, I will walk you through the four main types so that you know what kind of switch is compatible with your unit.

  • Vertical Switches

These are switches that rely on a piggyback plug, and they are relatively easy to install, thus making them ideal for standard installations. If you are looking for an affordable switch that has excellent quality, then a vertical switch should be your best option. This kind of switch works pretty well in small diameter basins. A vertical switch comprises a rod, a float, and a reed switch that is enclosed within a fixed housing.

Basically, this switch relies on the movement of the float to turn the pump on and off. As the water in the sump basin increases, the float will rise with the water level. Once the float reaches a certain height, it will activate the switch and turn the pump on. The float will then fall with the water level until the switch is flipped after crossing the set height. This in turn will cause the pump to shut down.

  • Tethered Switch

If you are a DIY guy, this is probably the switch you have been using at home. A tethered switch is compatible with a pedestal sump pump. This kind of switch comprises a float that is holding mercury or a steel ball inside. The float is then attached to the basin lid or pump with a cord.

Once the water level rises, the float will extend the cord until it starts to pivot. The switch will continue to float until when the steel ball or mercury will sink and energize the switch. The same thing happens when the water level begins to fall. Basically, the cord will extend downwards until the ball or mercury sinks to the opposite side, thus triggering the pump to turn off.  A tethered switch can only be installed in a large basin because it requires a lot of space.

  • Electronic switches

As technology continues to advance, companies are now manufacturing electronic float switches. They are relatively new in the market, and most people say that they are much more effective compared to other switches. Unlike other switches, electronic units have very few moving parts, if any.

Electronic switches come in two kinds, with one type having a single or two floats enclosed in a cage while the other type features a probe that is attached at your desired level. Most people are leaning towards electronic switches because the control box is located on the outside. At least the switch will have a prolonged lifespan since it won’t be submerged.

  • Diaphragm Switch

The other type of float switch you are likely to come across is the diaphragm switch. This type utilizes a piggyback plug, and it relies on pressure to activate. A diaphragm switch is placed on the lower side of a sump pump so that it works perfectly.

When the water level in a sump basin rises, more pressure will be exerted on the switch until it activates and turns the sump pump on. On the other hand, if the water levels fall to the required level, the pressure on the switch will reduce and cause the pump to turn off.

How To Replace A Sump Pump Switch

If you notice that your sump pump is not working as it should, then know that the float switch requires to be replaced. A switch can easily get damaged because of debris buildup and lack of proper maintenance. Below are the steps you should follow when replacing your sump pump float switch.

Before you proceed to replace the switch, it is important to let the sump pump run until it drains all the water from the sump basin. After all the water has drained, you can now disconnect the unit from the power source.

The next step is to locate where the float switch is and remove it from the sump pump. Unscrew the connection on the float switch so that you can access the electric switch. Remove the damaged switch and attach the new one using waterproof glue and leave it to dry. Once the glue dries, reassemble the float switch and connect it to the sump pump. Remember to seal all the areas that had been closed previously.

If you feel that the above procedure is complicated for you, then you should attach a plug-in switch. You just have to add a new external float switch with a piggyback plug so that you can bypass the circuit of the existing float switch. Make sure you use silicone to seal the housing. Once you are through with that, attach the new switch to the pump enclosure using a zip tie. Now plug the switch into the outlet and connect the bypass plug into the switch. Make sure you make the right adjustments so that the pump will turn on at your preferred water level. Once you are satisfied with everything, secure the new float switch by tightening the zip tie.
