How Do I Connect Alarm Floats To Septic Tank? (TOP 5 Tips)

  • Divide average day flow by gallons per inch or liters per mm of the tank chamber or basin to determine the necessary distance from the Timer On/Off to the float above it. Set this switch at least 4½ inches (114 mm) above the top of the filter car-tridge if a Redundant Off/Low-Level Alarm (R/O) is used, at least 3 inches

How does septic alarm float work?

A float switch inside the tank tells the pump when to come on, and a separate float switch operates an alarm that comes on when the water level exceeds a preset minimum. Aerobic septic systems also need alarms, even if the ground doesn’t slope.

Where is the float switch on a septic system?

For switches and alarms that can be installed into new septic tanks, a side-mounted float switch might be a better option. These switches are run through the side of the tank, rising and falling with water levels to an open or closes position.

Do all septic tanks have alarms?

All septic systems that use a pump to move wastewater from a septic pump tank to a drainfield or mound have an alarm installed in the house. The alarm goes off when wastewater is not being pumped from the septic pump tank to the drainfield or mound.

Why does my septic alarm go off when it rains?

Heavy Rain – Heavy rain causes groundwater seepage into your septic system. When it overflows, your alarm may go off. Parts Problem – Your alarm will likely go off if one of your septic system’s components is faulty. It could be your pump, floats, your timer – or the alarm itself.

How long does it take for septic alarm to go off?

To clarify, an alarm signal from the septic system does not mean sewage is going to immediately back up into the house. The alarm is set up to go off at a time that will allow for 24-48 hours of regular usage (though you should try to minimize usage) until a backup will happen.

How to Wire a Septic Pump Alarm

Home-Diy Septic system alarms notify the homeowner if there is a possibility of a sewage backup. Internally, a float switch that is anchored to a fixed point in the tank floats up and down in response to the level of the liquid in the tank. When the liquid level rises over a certain threshold, a switch inside the float shuts the alarm circuit, resulting in the alarm being activated. When the length of the sources is equal to zero, this.parentNode.removeChild(sources); otherwise, this.onerror = null; this.src = fallback; )(,, ‘, /public/images/logo-fallback.png’) ” loading=”lazy”> ” loading=”lazy”> Septic alarms notify homeowners when there is a problem with their septic system.

While one wire is dedicated to powering the pump, the other is dedicated to the septic pump alarm circuit.

The connection of the float switch to the alarm circuit is still the responsibility of the homeowner in this case.

  • Electrical conduit
  • Septic alarm float
  • Screwdriver
  • Septic alarm with mounting hardware
  • Junction box with cover Two wire nuts for wire with a gauge of 12 AWG


By gently pushing on the wire connections, you can determine whether they are secure. Physically raising the alarm floats to their upright position will allow you to test the alert. The alarm will ring if everything is done correctly.


A junction box must not be connected to the septic tank via a direct conduit. Gases from the septic tank might seep into the connection box and pose an explosive threat to the surrounding area.

At the Tank

  1. Locate the float wires for the alarm system as well as the alarm circuit wires that lead to the home. (They should be clearly labeled.) Push the wires through the electrical conduit and into the junction box as quickly as possible. To assemble the black wires, hold the bare ends of each together and place the pair into a wire nut, twisting it until it is secure. Carry out the same procedure with the white wire and the other wire coming from the float switch
  2. Install the junction box lid and tighten it down to hold in all of the electrical wire.

In The Home

  1. In a high-traffic area near the incoming septic tank alarm wires as well as an electrical plug-in, install the alarm. Incorporate the mounting screws into the alarm housing by threading them through the mounting holes. Screw the alarm into the wall. Connect the black wire coming from the septic tank alarm circuit to the positive terminal of the alarm system. Connect the white wire to the negative terminal on the circuit breaker. Screw the terminal lugs all the way down until they are tight. The alarm’s power connector should be inserted into the power receptacle.

The Drip Cap

  • Septic system alarms notify the homeowner that a sewage backup is impending
  • Nevertheless, they are not always effective. Float switches are located inside the septic tank and are connected to a fixed point in the tank. (Float switches should be clearly labeled to indicate where they are located.) The alarm’s power connector should be inserted into the power receptacle.

Second, is it necessary to install a septic alarm? Because gravity does not cease to function, there is no requirement for an aseptic tank alarm to signal a possible problem with the pumping system in an electrically powered pumping system. If you want to understand more about whether or not your septic system requires electricity, check out this article. Also, are you aware of how to connect a septic system? How to Install a Septic System Wiring Diagram

  1. Incorporate a direct burial cable between your home’s breaker box and your septic tank. Ensure that the wire is connected to a weatherproof electrical box placed outside the septic tank
  2. The plug wire from the septic tank pump should be run up and out of the tank and into the new electrical box, as shown. Piggyback plugs should be used for the control wiring.

What is the cause of a septic alarm going off? In analarmon aerobic systems, the failure of the aeration device or a high water level within the tank are the most common causes of failure. Assuming you have an in-tank-aerator, removethe cover of the aeration chamber and check to see whether or not the aerator is operating. This is the source of your alert if the aerator is not running or is not releasing air.

How a Septic Tank Alarm Works

A septic alarm provides you with early warning of potentially serious problems. iStock/Getty Images image courtesy of Katarzyna Bialasiewicz/iStock An effluent pump is required in any typical septic system in which the drain field is located at a higher elevation than the tank in order to move wastewater from the tank to the drain field.

The pump is controlled by a float switch located inside the tank, and an additional float switch runs an alarm that sounds when the water level in the tank drops below a certain minimum. Even if the ground does not slope, aerobic septic systems require alarms to function properly.

The Need for a Septic Alarm

Septic systems that are gravity-fed transport waste from the house to a holding tank where solids settle to the bottom and overflows leave through an outlet onto the drain field. Whenever a pump is required to convey waste to a higher elevation – as is frequently the case – the pump is activated by a float, similar to the one found in a toilet tank. Pump or float failure can cause major difficulties, such as a sewage backlog in the home or an overflow of the tank’s holding tank. If the system generates an alarm, the problem may be identified and remedied as soon as possible, avoiding the worst repercussions.

Alarm Operation

The septic alarm is activated by a separate float switch, which should be connected to a separate electrical circuit in order for it to continue to work even if the breaker controlling the pump is thrown. When the water level reaches the preset cut-in point for the float switch, a buzzer, a light, or some other alarm mechanism may be activated, which may be positioned on the tank, on the side of the house, in the basement, or in a utility room, depending on the configuration of the switch. Alarms connected to a municipal grid are required in some areas so that authorities may monitor sewage systems that are not operating properly.

What the Alarm Means

When a septic alarm goes off, it typically signifies that the water level in the tank has risen too high, which indicates that the pump is not working properly. It’s possible that the circuit breaker that controls it has tripped, and all you have to do is reset it to correct the situation. Another possibility is that the pump is blocked and has to be repaired, or that a continuous leak is forcing it to work too hard as a result of its overwork. The worst-case situation is that the drain field becomes clogged, and the pump is unable to rid the tank of waste materials.

Aerobic Septic Systems

In an aerobic septic system, compressed air is pumped through sewage in order to encourage decomposition. This sort of system also requires an alert to function properly. It is regulated by a switch that is sensitive to air pressure, and when it trips, it typically indicates that the compressor pump is not working properly. It is common for this sort of system to contain a separate storage tank for treated water as well as a pump that directs the water to pop-up sprinklers that distribute it over the drain field.

How to Troubleshoot Septic Float Switches

Septic tank alarms and float switches are included with your septic system if it employs a pump to transport wastewater from the tank and onto a drain field. Septic tank alarms and float switches are optional. When the float reaches an unacceptably high level, an alarm is activated to alert you that your tank may be on the verge of overflowing. It is possible for the float switch to fail and cause the alarm to ring even when the tank is not overflowing.

Attempt solving the problem yourself first before calling a service expert for assistance. Consult your unique float switch user manual for precise information on where to locate the various components.

Step 1

If the float’s alarm is sounding, turn off the alarm switch on the float. An overflow in the system or a defective float are both indicated by this condition.

Step 2

Anything plumbing-related in your home that discharges water into the septic system, such as the washing machine and dishwasher, must be turned off immediately.

Step 3

Anything plumbing-related in your home that discharges water into the septic system, such as the washing machine and dishwasher, must be shut off immediately.

Step 4

The float switch should not be turned off by checking the circuit breaker or the GFCI plug (Ground Fault Circuit Interrupter) for a trip. If moisture is allowed to enter the outlet, the GFCI plug will trip. When the circuit is tripped, a light will illuminate to show that it has happened. Attempt to reset the GFCI plug by pressing the button on the plug, or turn off and on the circuit breaker to reset the circuit breaker. If the circuit breaker or GFCI outlet trips again, this indicates that there is a problem with the wiring or that there is moisture in the circuit.

Step 5

Check to see if the pump is activated by pressing the on/off switch on the float switch. A dead switch or a defective pump might be to blame if this doesn’t work for you.

Step 6

Examine any exposed cables and wires to determine whether they have been damaged.

Septic Solutions provides free same-day shipping on all of our septic tank alarms, making them a great value.


Outdoor septic tank alarms are constructed with a waterproof casing that may be put outdoors on a post, the side of a building, or the side of a home, depending on the weather conditions. A float switch goes from the inside of the septic tank to the alarm box, which may be located anywhere on the tank’s exterior. When the water level in the septic tank rises over a certain level, the float switch will activate an alert light and buzzer.


Septic tank alarms mounted on pedestals are also suitable for outdoor installation. It is possible to install these alarms straight into the ground because they are supplied with their own pedestal post. These allow for a very simple and clean installation process. A float switch goes from the inside of the septic tank to the alarm box, which may be located anywhere on the tank’s exterior.

When the water level in the septic tank rises over a certain level, the float switch will activate an alert light and buzzer. The pedestal alarms are often equipped with connections for a submersible pump, which is quite convenient.


They are also suitable for exterior placement on a pedestal septic tank alarms. There is a pedestal post included with these alarms, which may be buried straight into the ground. Installing them is a breeze, and they are completely clean. In the septic tank, a float switch links the tank to an alarm box, which may be located anywhere in the tank. When the water level in the septic tank grows too high, the float switch will activate an alert light and buzzer. The pedestal alarms are sometimes equipped with connections for a submersible pump, which is useful for flooding situations.


Alarms with wireless capabilities are available from us. The first is our VersAlarm Wireless System, which is a wireless alarm system. This features a wireless float switch that has a range of up to 3250 feet and can transfer data to the alarm box wirelessly.

A wireless indoor alarm that connects to your existing wireless network is what this device is designed to be.

Tank Alarm Installation ? – Community Forums

Hello, I need to make sure that my tank alarm is properly installed at the absolute least, but I am concerned that I may have more serious issues. Here are the specifics; any suggestions would be greatly appreciated. The house was constructed around two and a half years ago. The alarm for the septic tank was never installed. I discovered the alarm system that had been left but had not been installed about a week ago. It is a Tank Alarm that has been activated. I didn’t have any directions, but I discovered this on the internet.

  1. I turned off the electricity to that line.
  2. All three black (hot, confirmed) wires were connected at the same time.
  3. The white wires running from the control panel to the septic pump were joined together.
  4. What I did was to ensure that all three grounds remained linked.
  5. It was necessary to keep the white wire coming from the main electrical box and the white wire leading to the septic pump linked.
  6. I plugged the tank alarm plug onto an existing outlet and it worked perfectly.
  7. For the first time ever, the septic service technician came to our house today to pump our tanks.

During the process of removing the second lid, the pump started in and began lowering the level from the first tank to the right level, which took several minutes.

He inquired as to whether the drains had been sluggish.

As soon as he departed, I opened up the electrical junction box near the tanks and discovered that there had been moisture in there for quite some time, as the key ring had rusted away and there was a white film covering much of the interior of the junction box.

I’ve gone back and rewired the junction box in the house in the manner in which it was originally installed, thus turning off the alarm once more.

At the very least, by doing this task, I will be notified if there are any difficulties that are not related to my actions.

I want to consult with a professional, but I would appreciate any comments, if for no other reason than to ensure that I have a vague understanding of what I’m talking about. Thank you for any information you may provide.

What do I do if My Septic Alarm is Going Off?

In the event that your septic alarm goes off, it may surely create some anxiety and uncertainty; and if you happen to be experiencing this right now, then you’ve arrived to the correct location! Don’t be concerned; it does not necessitate urgent action. Instead, take your time to go through this full essay so that you will be prepared to act now or in the future if the situation arises. What Septic Systems Are and How They Work The alarm works in conjunction with the septic system to alert you when the water level within the pump tank has increased to an unsafe level or has decreased to an unsafe level.

  • The timer is in charge of regulating the time intervals during which the pump is permitted to pump wastewater into the drainage system.
  • Thus, during periods of excessive water use, the drain field is kept from getting overflowing, which might cause damage to the drainage system.
  • A large amount of water is injected into the system in between pumping cycles for whatever cause, and the water has nowhere else to go but back into the system’s pump tank.
  • Depending on how much water was and continues to be put into the system and how the pump is set up to operate on a timer, it may take many pumping cycles until the water levels are returned to normal.
  1. There is an excessive amount of water being put into the septic system. This is the result of excessive water use, which might be caused by multiple loads of laundry, an excessive quantity of dishwashing, or a disproportionate number of long showers.
  1. Somehow, groundwater is making its way into the system. If there is an excessive amount of standing water surrounding the septic tanks, whether generated by rain or another source, the water may seep into the tanks and cause the internal water level to rise.
  1. It’s possible that one of the components of the septic system is malfunctioning. If anything goes wrong with your system — including the pump and floats — the alarm and timer will go off and the septic system will stop working correctly.

The Best Thing to Do If Your Alarm Goes Off Alternatively, if you hear an alert, you should press the red button or turn on the alarm box. The alarm will be turned off as a result of this action. There should be a red light and a green light on the alarm box, which should be situated someplace on the unit. The green light indicates that the alarm is operational and should be left on at all times. It is shown by a red light if the alarm is getting a signal from the pump tank indicating that the water level is increasing above or decreasing below what is expected.

  • If the breaker occurs to be tripped, look around the septic tanks to see if there is any standing water.
  • It is possible that the red light on the alarm box will go out on its own after allowing the septic system to operate for a couple of pump cycles (which should take approximately 10-15 hours).
  • If the red light turns off, it signifies that the system is operating properly and that it only needs to catch up with the extra water that has overflowed into the storage tank.
  • To be clear, an alarm signal from the septic system does not always imply that sewage is about to back up into the house right away.
  • Do you require septic system repair on a regular basis or emergency service?

Pump Alarm Service

Generally speaking, septic effluent pumps are used to transfer cleared septic effluent out of a septic tank to a drainfield in systems where a gravity system cannot be utilised. Although septic effluent pumps are not required to transport solids, they must meet higher durability criteria and perform more difficult tasks than a normal sump pump, which is designed to drain ground water from a structure. Septic effluent pumps are commonly employed in septic systems where the absorption bed is positioned above the level of the septic tank, as seen in the illustration.

What should I do when my septic tank pump alarm goes off?

First and foremost, do not panic. You have time to respond. The alarm is sounding to alert you that the water level in the tank has risen to an unsafe level as a result of the pump failing. A float in the tank is responsible for setting off the alarm. The float’s goal is to turn over as the water level continues to rise, causing an alarm to go off. To save yourself from going nuts, turn off the alarm. 3.Decrease water consumption. no laundry, dishwashing, showers, or toilet flushing till further notice.

  1. Check the breaker box in your home.
  2. If the breaker has been tripped, the breaker must be flipped.
  3. If the alarm goes off again, contact Lentz Wastewater immediately.
  4. Reduce or restrict your water consumption until a remedy is found.

What is causing my septic alarm to go off?

There are a variety of reasons why a submersible pump may cease to function, including:

  • It is possible for a submersible pump to stop operating for a variety of reasons. Some of them include:

Regardless of the reason for the failure, a septic alert must be treated immediately. If you ignore the alerts, septic waste can back up into your home and cause damage to your drainage system. Pumps that are inefficient are repaired or replaced by Lentz Wastewater. For new installations as well as septic pump replacements, we only utilize Goulds Pumps. There is a distinction, and we exclusively put our faith in the Goulds Pumps because of their superior quality and effectiveness.

How to Check Your Septic Panel and Pump Chamber

It is recommended that you inspect your pump chamber once a year to ensure that everything is in proper working order. Follow the 11-step procedure outlined below to complete this task on your own! (Do you require further assistance? Alternatively, you may watch our instructional video below.)

‍ 1. Let’s start by inspecting the panel. Make sure the power is on by verifying the power switch to the panel is on.

The following items should be included in this general overview: The electrical box may be seen in the lower left corner of the image below, starting at the bottom of the image.

Check to verify that all of the cables are firmly connected before using it. Next, take a look at the lower right corner of the shot, where you can see the discharge pipe for the pump. Check to see if it is operational (valve should be lined up with pipe). It’s now time to have some fun!

‍ FIRST.PUT ON GLOVES!That is one step you DO NOT want to miss. Remove the float tree (the pipe with a pvc handle located upright left in our picture) and pull up the alarms.

*Please keep in mind that these instructions are for a 4-float system. Some systems contain only two or three floats.

If you don’t hear an alarm, this is cause for concern. Starting at the top, I will explain the floats and how to ensure each one is working.

The following instructions are for a four-float system. Only 2 or 3 floats are present in some systems.

7. Continue testing.

Check that the pump is operating properly by flipping the second float from the bottom upside down and then turning it back around. With your other hand, turn the next float up (which would be the second from the top) upside down while still holding the first float. You should be able to hear the pump start up. As soon as you have confirmed that the pump is operational, just release these two floats. There’s one more float to go. The top float serves as an alert in case of high water. Turn it over down to see whether this is the case.

8. Now is the time to inspect the power cords.

Check to see that everything is securely tied to the float tree and not just hanging free. Zip ties can be used to reattach any stray cables.

9. Securely return the float tree to its holder and coil any dangling cords so that they are out of the water.
