Best Sump Pump Float Switch: The Buying guide
Here are a number of factors that you have to consider when buying a float switch for your sump pump.
The type of float switch
Yes, everything that has been made is available in various types and so are float switches. In fact, it is mainly of two types and each operates in its own way.
Vertical Float Switches: These are the switches that use a rod to float up and down. The rod is usually made of stainless steel while the switch itself has is an air-filled core. This type of switch is particularly good for narrow sump pumps because this one takes narrower space to work and get installed.
Actually, the vertical float switches are better for starting shorter pump cycles. In fact, it uses less electricity when it is working. So, these are the benefits of a vertical float switch.
Tethered Float Switch: If you are using a wide and deep sump pump then a tethered float switch will serve you better. This one uses no rod and covers most of the sump pump. So, it is bigger in size.
Likewise, it helps to start longer cycles of pumping and consumes more electricity. If you are using a very powerful sump pump then this is most likely the type of float switch that will serve you best.
The Size of the Switch
There are various kinds of sump pumps available and not all have the same design and size. Therefore, when you are out looking for a float switch make sure that it is compatible with the sump pump you have at home. In fact, it has to be of the right size to fit the sump pump.
