Zoeller Sump Pump Float Adjustment

If you have a Zoeller sump pump, you may need to adjust the float from time to time. This is a comparatively simple process, but it’s essential to do it correctly so your pump continues to work properly.

A sump pump float switch is a device that automatically turns the pump on and off as needed. The float switch consists of a float attached to a long arm and a switch connected to the pump. The basis of the float switch is to prevent the pump from running dry and damaging the impeller. The float switch also prevents the pump from over-cycling, damaging the motor. Most sump pumps have an adjustable float switch, which allows you to set the depth, which ensures the pump will turn on and off.

This blog post will show you how to adjust the float on your Zoeller sump pump. We suggest consulting these troubleshooting tips if you’re having trouble with your floats.

What Is a Zoeller Sump Pump?

A Zoeller sump pump is a submersible pump typically used to remove water accumulated in a sump pit. The pump is connected to a discharge pipe that runs to a drainage area, such as a storm sewer or dry well.

The float switch assembly on a Zoeller sump pump controls the pump’s automatic operation. When water levels in the sump pit are high, the float switch will rise and activate the pump. It then deactivates the pump when the water level drops below the activation point.

Why Is It Essential to Adjust the Float on a Zoeller Sump Pump?

A Zoeller sump pump float is a small, buoyant object that sits on top of the water in a sump pit. The float activates the pump when it rises to a certain level and deactivates it when it falls back down. If the float is not adjusted correctly, the pump will either run too often or not often enough.

Over time, the float can become stuck in one position due to mineral deposits or other debris. This can cause the pump to operate constantly, which will shorten its lifespan and increase your energy costs. It can also cause the pump to turn off too soon, allowing water to build up in your basement and lead to flooding.

To prevent these problems, adjusting the float on your Zoeller sump pump at least once a year is essential. If you have hard water or a dirty sump pit, it may be necessary to do it more often.

Zoeller Float Switch Types

There are three Zoeller float switches: the vertical float switch, the tethered float switch, and the piggyback float switch.

The most common type of Zoeller float switch is the vertical float switch. It is mounted on the side of the sump pump and has a float that rises and falls with the water level. The float activates the switch and turns on the pump when the water level gets to a certain point.

The tethered float switch is similar to the vertical float switch but has a tether that stops it from moving too high or too low. This type of Zoeller float switch is often used in smaller sump pumps.

The piggyback float switch is mounted on top of the sump pump and has two floats: one that turns on the pump when the water level rises and one that turns off the pump when the water level falls. This type of Zoeller float switch is often used in larger sump pumps.

How Do the Zoeller Float Switches Attach to the Pump?

The Zoeller float switch is a small, disk-shaped device that attaches to the side of the sump pump. A hole in the float switch’s center and a small rod or wire extending from the hole. The other end of the rod or wire is attached to the pump.

When the water level in the sump pit increases, the float switch floats on top of the water, the float switch arise with the water level, and as it does, it pulls on the rod or wire attached to the pump. This activates the pump, which then begins to remove water from the sump pit.

As the water level in the sump pit goes down, the float switch sinks. When it reaches a certain point, the float switch releases the rod or wire, and the pump shuts off.

Can You Adjust the Float on a Zoeller Sump Pump?

You can adjust the float on a Zoeller sump pump by removing the float assembly and adjusting the float arm. The float arm controls the switch that turns the pump on and off. To remove the float assembly, unscrew the retaining nut and pull the assembly out of the pump housing. To adjust the float arm, loosen the set screw and move the arm up or down to the desired position.

Can You Adjust the Sump Pump Float?

One of the most common questions regarding sump pumps is, “Can you adjust the sump pump float?” The answer is yes; you can adjust the sump pump float.

The float is the sump pump part controlling the pump’s automatic turning on and off. The pump will turn on when the water level in the sum pit reaches a certain point. The float activates the switch, which sends water to the pump. As the water level lowers, the float deactivates the switch, and the pump turns off.

Sometimes, the float may not operate correctly due to factors such as a clogged intake screen or a change in the water level in your home. When this happens, you may need to adjust the float.

Type of Floats

There are two types of floats: mechanical and electrical. Mechanical floats are attached to a lever that activates the switch when it rises with the water level. Electrical floats are connected to a wire that runs to the switch.

First, locate the adjusting nut on top of the float arm to adjust a mechanical float. Loosen this nut and raise or lower the arm until the float turns on at the desired water level. Tighten the back-down nut once the adjustment is made.
To adjust an electrical float, first, locate the adjusting knob on the float. Rotate the knob clockwise to raise the water level at which the pump turns on or counterclockwise to lower it.

If you have difficulty adjusting the float or the pump keeps turning on and off more frequently, it is best to call a plumber for assistance.

How High Should the Float Be on a Sump Pump?

The Zoeller sump pump float is adjustable to fit various sump pit sizes. The recommended setting for the float is 1/2″ to 1″ below the rim of the sump pit. This will ensure that the float assembly does not come in contact with any debris in the pit and that the pump will operate properly.

How Do You Adjust the Float Arm on a Sump Pump?

If your Zoeller sump pump has a float arm, you may need to adjust it from time to time to keep it working correctly. Here’s how to do it:

  1. Locate the adjustment screw on the side of the float arm.
  2. Use a screwdriver to turn the screw clockwise or counterclockwise, depending on which way you need to move the float arm.
  3. Test the pump by turning it on and letting it run for a few minutes. If it seems to be working correctly, then you’re done!

What Happens if the Float Is Set Too High?

If you set the float too high, the sump pump will turn on more frequently and will not pump as much water each time. This can cause the sump pump to overheat and fail prematurely.

What Happens if Your Float Level Is Too High?

If your float level is too high, the sump pump will run continuously and may overheat. This can damage the pump and shorten its lifespan. Additionally, your electricity bill will be higher if the pump runs constantly. To avoid these problems, adjust the float level to just above the sump pit’s water level.

What Should My Float Height Be?

Assuming you have a Zoeller sump pump, the float height should be adjusted so that the float switch is level with the bottom of the pit. This will ensure that your pump will operate as efficiently as possible.

Is the Lower the Float, the Better?

The float on a sump pump tells the pump when to turn on and off. The lower the float, the sooner the pump will turn on. This can be beneficial if much water goes into your sump pit. However, it can also cause the pump to cycle more often, which can shorten its lifespan.

How Do You Know if a Float Is Terrible?

If your sump pump appears to be running more than usual or if you notice water pooling around the unit, it’s possible that the float switch is not working correctly. A damaged float switch can cause the pump to run continuously, which can shorten its lifespan and increase energy bills.

You can test the float switch by manually moving it up and down. If it doesn’t move freely or feels stuck in one position, it’s likely damaged and will need to be replaced.

Conclusion

If your Zoeller sump pump isn’t working correctly, it could be because the float needs to be adjusted. This relatively easy process can be done in a few minutes. With these few tips, you should be able to adjust the float on your Zoeller sump pump correctly. Always refer to your Zoeller sump pump manual for instructions on properly maintaining and troubleshooting your unit. By keeping your Zoeller sump pump float in good working condition, you can help prolong the life of your pump and avoid costly repairs down the road.
