Can a Zoeller Sump Pump Float be Adjusted: 4 Types [Discussed]

Last Updated on May 7, 2023

The Zoeller Sump Pump is designed to alleviate your concerns about dealing with a persistently wet or flooded basement. But what happens when your sump pump isn’t operating at the right level? Can you adjust the float switch on your Zoeller sump pump to better suit your needs?

While it is true that you can adjust the float switch on any Zoeller sump pump, there are limitations on specific pump models. For instance, if you have an automatic unit with a self-contained float switch, the pumping range is not adjustable.

But if you have a nonautomatic unit controlled with a separate pump switch, the pumping range can be adjusted according to your needs. So read on to discover the details on Zoeller sump pumps and how you can alter the float switch system.

How Can a Zoeller Sump Pump Float be Adjusted

How Do I Know If My Zoeller Sump Pump is Adjustable

The best way to determine if your Zoeller sump pump is adjustable is to check the product’s documentation. Look for instructions manuals or online information about the product that specifies whether it has adjustable settings. Your local retailer may also be able to provide this information if you cannot find it yourself.

If the documentation does not specify whether the sump pump is adjustable, look at its features and design. Many non-automatic Zoeller’s adjustable sump pumps have adjustment switches on the side, allowing users to adjust their water levels and flow rate manually.

Available Types of Adjustable Zoeller Sump Pump Float Switch

Available Types of Adjustable Zoeller Sump Pump Float Switch

Various types of adjustable Zoeller float switches are available on the market, each offering its benefits and features to homeowners.

Mechanical Tether Switch

A mechanical tether switch is an adaptable Zoeller sump pump switch with a rigid arm attached. The arm contains magnets that can be adjusted by turning a knob or pushing a lever to set the desired water level that triggers the on/off switch for the sump pump.

This type of float switch is easy to install and requires minimal maintenance due to its robust construction. It is also less susceptible to damage as it contains fewer electronic components, which flooding events in your basement or crawlspace could easily damage.

Magnetic Switch

Another type of adjustable sump pump float switch is the magnetic switch. This type utilizes a simple magnet that holds the attached float in place, allowing it to toggle between “on” and “off” positions when water levels rise or fall.

Unlike mechanical tether switches, these switches provide more precise control over when the pump will activate or deactivate. But, they require additional wiring for installation and may be cost-prohibitive for some households due to their complexity and added expense.

2-Pole Snap Action Switch

A 2-pole snap action float switch comes with two independent connections at either end, simultaneously detecting changes in both high and low water levels.

This feature makes it ideal for applications where varying levels need to be monitored, such as pools or aquariums with changing water levels due to rain storms or evaporation rates, respectively.

It also has improved shock resistance properties compared to standard snap action switches. It can react more quickly as soon as any change in pressure is detected due to its two poles sensing two different pressures.

2-Pole Enhanced Switch

A 2-pole enhanced float switch is similar in design and function to a regular 2-pole snap action. Still, it offers additional features such as improved reliability from surge protection circuits built directly into the device and better accuracy to advanced microprocessor technology.

This allows users greater control over high and low thresholds for monitoring changes in their water level when using these devices in conjunction. It makes them ideal for applications such as swimming pools or aquariums where precision measurements are essential.

STEP 2. Adjust the Float Switch

Depending on your Zoeller sump pump model, there are two main types of float switches: vertical and tethered. The steps for adjusting each switch type are as follows:

Vertical Float Switch:

  1. Locate the vertical float switch attached to the sump pump, often positioned vertically.
  2. If needed, loosen the switch using an adjustable wrench or a pair of pliers. Carefully turn the clamp counterclockwise to avoid damaging the switch.
  3. Adjust the float switch to the desired height by sliding it up or down the pump body.
  4. Tighten the clamp clockwise to secure the float switch in place.

Tethered Float Switch:

  1. Identify the tethered float switch, typically attached to the side of the sump pump by a flexible tether or cord.
  2. Loosen the screw or clamp on the tethered float switch, allowing easy adjustment.
  3. Adjust the float switch by extending or shortening the tether to achieve the appropriate height.
  4. Secure the float switch in the desired position by tightening the screw or clamp, ensuring proper function and performance.

STEP 3. Test the Sump Pump

Once you have adjusted the float switch, you must test the sump pump to ensure it functions correctly. To do this, follow the steps below:

  1. Reconnect the Zoeller sump pump to the power source by plugging it back into the electrical outlet.
  2. Pour water into the sump pit until it reaches the float switch’s height. Observe whether the sump pump activates and starts pumping water.
  3. If your sump pump works correctly, it should turn on when the water level reaches the adjusted float switch height and turn off when it drops.

STEP 4. Readjust the Float Switch (If Needed)

If your Zoeller sump pump does not turn on and off as desired during the test, it may be necessary to readjust the float switch. Repeat the steps mentioned in step 2 to fine-tune the height of the float switch. Then retest the sump pump. Perform this process until your sump pump operates at the desired performance level.

What Happens If a Zoeller Sump Pump Float Level is Not Adjusted Correctly?

What Happens If a Zoeller Sump Pump Float Level is Not Adjusted Correctly

If not adjusted correctly, the Zoeller Sump Pump can become clogged and overloaded, requiring expensive repairs. The following are some of the issues that can arise if the float switch is not adjusted to the right height:

Blockages: When the float switch isn’t set at an optimal level, sediment and debris can build up within the pipe or around the unit, causing blockages and restricting water flow. This could eventually cause problems with overheating and electrical failures due to an overburdened motor.

Overflow of Water: Not adjusted Zoeller sump pump could also cause an overflow of water into your basement or crawlspace due to improper drainage. If this occurs, there’s a risk of flooding or structural damage caused by excessive moisture levels in these areas.

Inadequate Pumping Capacity: When the float switch is set too low, less water will be pumped out from your basement or crawlspace before the system stops running. Any excess moisture won’t be drained away adequately, leaving behind high humidity levels, which could lead to mold growth or rusting of metal fixtures.

Unusual Sounds: If you notice odd humming sounds from your Zoeller sump pump, it could mean something isn’t running correctly internally due to incorrect adjustments. This should be addressed immediately.

Electrical Wiring Issues: Another warning sign that something may be amiss with your Zoeller sump pump is if you notice scorch marks around it or on its wiring. This could indicate that too much electricity has been sent through a faulty connection due to incorrect settings.

How High Should I Set My Zoeller Sump Pump Float After Adjusting?

To achieve optimal performance and ensure adequate water extraction from your basement, you should set the Zoeller sump pump float a few inches above the top of the sump pump motor. This positioning allows the pump to activate at the correct water level and maintain high efficiency.

Also, positioning the sump pump float too close to the motor can cause it to become overloaded quickly, leading to more expensive repairs or replacements. Too far away, it won’t be able to detect the correct water level when activated.

How Often Should I Adjust My Zoeller sump pump?

How Often Should I Adjust My Zoeller sump pump

Generally, you should examine and adjust (if needed) your sump pump system every three to four months to assess its effectiveness and adjust if necessary. During heavy rain seasons or periods of elevated groundwater levels, checking and adjusting your sump pump more frequently may be beneficial.

To check the float adjustment, inspect the following:

  • The float valve moves freely without being obstructed by debris or buildup.
  • The float valve is appropriately attached and functioning correctly.
  • The sump pump is turning on and off at the correct water levels.

If your sump pump fails to turn on, off, or operate at the correct water levels, adjust the float valve immediately to prevent flooding or damage to your property. Also, here are some tips for maintaining your Zoeller sump pump:

  • Inspect the float for any signs of wear, damage, or obstruction, and make sure it moves smoothly without any hindrance.
  • Inspect the pipe for damage and confirm that its termination point is appropriate to prevent water from flowing back into your basement.
  • Clean the impeller and intake screen that draws water into the pump and pushes it through the discharge pipe.

Should My Sump Pump be Fully Submerged After being Adjusted?

Zoeller sump pumps are designed as submersible, specifically designed to function underwater. Therefore, your sump pump should be fully submerged, except for a few integral parts that must not be underwater, usually including the power cord and the plug.

It is crucial to follow the manufacturer’s instructions for installation and placement and correctly maintain and adjust the Zoeller sump pump. When installing your sump pump, ensure it is placed on a solid, level surface in the sump pump pit to prevent sediment and debris from impacting its function or shortening its lifespan.

Keep Your Basement Dry by Adjusting the Zoeller Sump Pump

The float switch plays a vital role in determining the operation of your Zoeller Sump Pump. Although adjustments can be made to the tether point and length on any Zoeller sump pump, it’s important to note that the pumping range depends on whether your unit is automatic or non-automatic.

An automatic Zoeller sump pump’s pumping range cannot be adjusted, while a nonautomatic pump controlled by a switch offers more flexibility in altering the pumping range. By understanding this fundamental difference, you can better determine what type of Zoeller sump pump suits your needs.
