What to do When Sump Pump Alarm Goes Off: 4 Things to Check and Fix

What to do When Sump Pump Alarm Goes Off 4 Things to Check and Fix

Often, the sump pump alarm going off usually indicates a problem in the system. It is essential to troubleshoot and identify the causes of the alarm before attempting to fix it.

1. Check The Power:

The first thing to do when your sump pump alarm goes off is to check if power is being supplied to it. Ensure all connections are tight and no wires have come loose or been disconnected from the unit.

You may also want to check for tripped breakers or fuses, as this may be causing a power issue. Inspect wiring for any signs of wear or damage, as this can also lead to power problems with your sump pump alarm system.

2. Check If Pump Has Been Blocked or Clogged:

If there is no power issue present, then it’s time to investigate why your sump pump alarm went off in the first place. Before checking anything else, ensuring nothing has become blocked or clogged within the sump pump is important.

This could be caused by an accumulation of debris such as leaves, rocks, sand, or other objects that have built up over time. They prevent the water from flowing freely out of the basin.

To prevent further issues with your sump pump system, make sure that you regularly clean out any blockages or clogs in the system regularly.

3. Check the Water Level Of The Basin:

You should also ensure that nothing is wrong with the sensors inside your sump pump system that would cause them not to detect water levels correctly. One way of doing this is by manually checking the water level in your basin using a measuring stick or another similar tool.

Also, see if it matches up with what your sensor is reading on its own. If there appears to be some discrepancy between these readings, then there might be something wrong with either one of them, and you should look into replacing the alarm sensor.

4. Determine If the Pump is Malfunctioning:

If all else fails and none of these solutions seem to work, you may need to consider replacing your entire sump pump system. Look for any corroded components inside of the unit as well as inspect moving parts like motors and bearings which could indicate a malfunction. Replace it if it’s too old or showing signs of wear and tear over time due to age or general neglect.

What Would Cause a Sump Pump Alarm to Go Off?

What Would Cause a Sump Pump Alarm to Go Off

The sump pump is a vital component of your home’s plumbing system, and its alarm can be a sign of potential problems. It’s important to identify the cause of the alarm to take the appropriate steps to remedy it. Here are some common causes for your sump pump alarm to go off.

1. Power Outage:

A power outage is one of the most common causes for a sump pump alarm to go off. When there’s an outage, the pump stops running and can no longer keep up with excess water in your basement or crawlspace.

If you don’t have a battery backup, the alarm will sound when it detects rising water levels due to a lack of proper drainage.

2. Clogging:

Clogging in the sump pump discharge line can also trigger an alarm. This usually happens when debris, such as dirt and gravel, builds up in the line and restricts water flow away from your property. If not addressed quickly, this could lead to high water pressure in the pipe and, ultimately, an overflow in your basement or crawlspace.

3. Wet Alarm Sensor:

In some cases, a wet sensor can be responsible for triggering an alarm. This type of sensor is located at the bottom of the sump basin and detects any liquid that has fallen into the area below it.

If too much water accumulates on top of this sensor, it may send out a signal that triggers an alarm even when there is no actual problem with your sump pump.

4. Sump Pump is Overworked:

If your sump pump is pushed to its limit due to inadequate capacity or lack of upkeep, it may sound an alarm when the workload becomes too much. If you experience frequent flooding or heavy rain storms regularly, upgrading your existing unit or installing a second one as a backup system might be time.

Other Causes of a Sump Pump Battery Backup Beeping:

Other Causes of a Sump Pump Battery Backup Beeping

1: Loose Wire Connections

Loose wire connections can also cause the battery backup system to start beeping, as they do not provide sufficient power for normal operation. To resolve this issue check all wiring connections and ensure they are securely attached and properly connected before starting up again.

If necessary, have an electrician come in and double-check everything just in case something was missed during the inspection.

2: Low Battery Fluid

You might hear a beeping noise due to low fluid levels, then this could also result in a beeping noise. Since batteries need regular maintenance, including topping up their fluid levels with distilled water every now and then.

Should not enough liquid remain inside the cells, it can cause problems with charging and lower performance over time.

3: Dying or Dead Battery

Your sump pump battery backup may also start beeping if its battery has died or is dying due to age or infrequent usage. If the reading falls below 12 volts then chances are good that it has already gone bad and needs replacement immediately.

If this happens, you’ll need to replace the battery immediately. Using an old dead battery will lead to reduced efficiency and eventually complete breakdown of your system over time. So it’s important to monitor its condition regularly especially if you live in areas prone to flooding where high-quality reliable backups are essential.

4: Bad Circuit Board

A faulty circuit board located inside these units may have gone bad due to either due age or some accidental external interference such as voltage spikes etc. So before replacing the entire setup try resetting the board first by disconnecting the power supply from the AC outlet.

Then press the reset button (if available) located near the board after a few minutes reconnect power. If this solves the problem otherwise opt for replacing the entire circuit board with a newly acquired one as soon as possible.
