How Battery Backup Sump Pumps Work

Most sump pumps have an automatic start/stop system, which is activated as soon as it detects water levels rising in the basement. It gets activated by access moisture or water caused by excessive rains, seepage of groundwater, etc. and the pump drains water through well-placed pipes. Well pumps work similarly. 

Typically sump pumps use AC power, so chances are they might not work during power outages – a common occurrence during adverse weather conditions. And that’s why it is essential to have a sump pump battery backup system, as it gets triggered if the existing sump pump fails to work when needed.


Benefits of Using A Backup Sump Pump in Your Home

Water damage leads to structural losses as well as mold and mildew infestations, etc. Therefore, a sump pump is required to pump the water out of the pit and away from the building to keep the basement or crawlspace dry. However, your house remains prone to water-related damages without a backup source. Here are some of the benefits of installing battery backup for the existing sump pump to keep it working even when:

  • There is a power outage
  • The primary pump has a mechanical issue
  • The primary pump gets clogged with dirt, debris, etc.

Battery Backup Sump Pump – Buyer’s Guide

Type Of Battery

If you are deciding on adding a battery backup to a sump pump, you have two options – Solar battery or AGM (Absorbent Glass Mat) Battery. A solar-powered sump pump battery backup requires you to place solar panels outside, but close to the backup battery.

An AGM battery-powered backup sump pump will require you to choose between deep cycle, marine, maintenance-free, and wet cell batteries. These usually supply DC and, if properly maintained, can last for a decade.

Size

While purchasing a battery backup, you need to consider the size of your primary sump and buy accordingly.

Some battery-powered backup sump pumps require unique configurations; please ensure you have enough space for precise installation before buying it. 

Another option is to buy a primary sump pump that already has a sump pump battery backup – that’d be better than installing two separate units that require extra space.

Wayne Sump Pump Battery Backup

Power & Voltage

A battery-powered backup sump pump does not require A/C power, so it will not be at par with your main sump pump. Don’t go for the cheaper variants that won't have enough backup or power to sustain throughout an outage.

Build Quality

The best battery backup sump pump needs to be made from durable materials so the machine can last for the long-haul. Here are some options to choose from:

  • Cast iron: Most pumps are made from this heavy-duty material as it can withstand severe weather conditions, but they can be quite heavy as a result.
  • Plastic:  A sump pump battery backup system made from plastic won’t do well under pressure – but its an ideal option if you don’t expect to use the backup often.
  • Stainless steel: These pumps last for a good number of years and are known for their corrosion fighting abilities.

Battery Charging

Sump pumps might come with a battery charger. Pay attention to the voltage of the charger – some take longer to charge than others. Knowing the voltage is essential for areas with frequent power breakdowns because you may not have enough charge between outages for the sump pump battery backup to run efficiently. Typically, two devices are needed charge batteries – an AC to DC converter, and a relay. Power is supplied from the socket to the relay, which then transfers it to the sump pump.

Pump Capacity

Ensure that the pump capacity of your battery-powered backup sump pump is enough to fulfill your requirements. If power outages are frequent where you live, you need to find a backup unit that is quick to charge with enough power capacity to drain out all water and moisture quickly. Ideally, the chosen pump should be over and above 35 to 60 GPM or more than 36,000 gallons per hour.

Ease of Installation

While choosing the best backup battery sump pump, remember to check the ease of installation to your existing sump pump, or will you need to customize the current setting. The good thing is that generally, a sump pump battery backup system is easy to install, it’s plug and play. However, you need to make sure that the chosen battery powered backup is compatible with your primary sump pump.

Other Features

An excellent choice is to go with the automatic option, which begins water evacuation when the primary sump pump halts its operations for some reason. Plus, you should choose a battery backup sump pump with an alarm that goes off when there is an issue. 

Price & Warranty

The cost of a backup battery sump pump varies between different models available in the market. The stainless steel or cast iron models are more expensive than the plastic variant. The warranty also varies between them; you should consider a brand that offers the most coverage.

Battery Powered Vs. Water Powered

Your choice between water powered backup sump pump vs. battery-powered backup depends on the amount of pressure you require and how often you suffer from power breakdowns. When the primary sump pump stops – the water backup sump pump activates by using city water. They remain connected with the drainage system, and a separate drain is used to keep flooded water away from the main water supply.

It is kept slightly elevated above the primary sump pump and requires at least a PSI of 40 to pump away gallons of water. The backup kicks in when there is a power outage or when the main pump malfunctions due to various reasons if the primary pump needs a helping hand, the backup pump runs on AC power. In contrast, when there is no electricity, it shifts to battery usage.

Also, it runs on a minimum of 40 PSI and can drain out 2,000+ gallons of water per hour if the vertical lift has at least a 10-feet rise. The water-powered option does not require electricity; it runs solely on water pressure so it can function for an extended period. The battery powered backup system will give as much time as its charge allows. However, water is drained out at a much quicker pace than water-powered backup sump pumps.


Installation of Battery Backup for Existing Sump Pump

If you are wondering how to add battery backup to the existing sump pump and whether you can do it yourself, the answer is yes, you can. Before commencing, please ensure that the purchased sump pump battery backup system is compatible with the existing sump pump.

  1. 1
    Connect the main pipe to the given PVC backup pipe – it should be long enough to extend out of the hose
  2. 2
    Ensure that the check valve is secure and separate it from the required pipes
  3. 3
    Measure the output charge with a hydrometer
  4. 4
    For your safety, please ensure there is no water where you carry out the installation process
  5. 5
    Adequately connect the negative (Black) and positive (Red) connectors on the battery
  6. 6
    Place the battery in a plastic box
  7. 7
    Loosen the nuts on the battery terminals by using a wrench to remove the cable.
  8. 8
    Remember the wrench and cable must never touch both the voltage ports, as that may lead to a spark or short circuit
  9. 9
    Connect the alarm to get notified if there is any problem with the system

Watch this video for a step by step guide on how to install a battery backup sump pump.


Storage, Maintenance & Troubleshooting

Ideally, a battery should be placed within the box. To ensure that everything runs smoothly, you should keep it maintained, and if an issue arises, get professional help to troubleshoot your device.

Maintenance 

Even if you buy the best rated sump pump with battery backup out there, its functions depend on how well you are at maintenance and upkeep. As a rule of thumb, it is best to run diagnostics every four to six months – remove the lid and then press the float switch, if water pumps the unit is working fine.

Also, check if the battery has enough fluids and its caps are clean from particulates, plus assure that all sensors are functioning correctly. Due to moisture, the chances are that the battery terminals may corrode – make it a point to clean them thoroughly regularly. Also, ensure that the pump and cord are running smoothly – if not, replace them.

Watch this video to understand how to carry forward with the maintenance and testing of your primary sump pump and its backup sump pump.

Trouble Shooting
  • Failed Battery

A good battery lasts for many years, and cheaper variants tend to fail much sooner – the bottom line is that all batteries fail eventually. If your battery is not responding, you need to upgrade to a newer, better battery.

  • Clogging

A sump pump may get clogged up because of debris within the pipes, and also when the float switch is activated many times. To create clear passage – use a lid to eliminate the chances of debris falling into the pit. However, if you regularly carry out thorough cleanups, you may not face such issues.

  • Unit Is Running Nonstop

Check for missing valves and stuck switches – fix what can be repaired and replace what cannot be repaired. Here is a video on how to run diagnostics and troubleshoot your sump pump.


How To Make Your Own Battery Backup Sump Pump

Following is a breakdown of how to make your own battery backup sump pump for ½ HP sump pump:

  1. 1
    Connect Dc to AC inverter, AC relay, battery (preferably marine), and ½ horsepower pump
  2. 2
    Ensure all parts remain protected against water splashes
  3. 3
    Connect the AC electric power cord with the AC relay – once everything is tightly fastened the other end of the power cord can be connected to a switch
  4. 4
    If all is done precisely thus far – the power outlet will supply power to the relay, which in turn will direct it towards the sump pump
  5. 5
    To test out the backup power; disconnect the current flowing from the power outlet – the relay switch should now activate the sump pump battery backup system
  6. 6
    Run a test – fill the slump basin with water and wait for the battery backup for the existing sump pump to kick in
  7. 7
    Reconnect the AC power cord, so the sump pump works on standard electricity, and the relay switch will only activate the backup battery if there is a problem or a power outage

Frequently Asked Questions (FAQs)

How Much Does A Battery Backup Sump Pump Cost?

There are many sump pump battery backup systems available in the market, and they can cost as little as $150 and can go up to $500 or more.

What Are Some Ways To Prevent Flooding During Power Outages?

A good sump pump will keep your basement clear of excessive moisture and water, and if there is an outage or a problem with the primary sump pump, a sump pump battery backup system will activate and work for up to 24 hours.  To further enhance protection, a generator can be used to run the main sump pump as well as to charge the battery. All in all, if all else fails, you should be equipped with a backup electric sump pump.

How Long Will The Battery Backup Last When Charged Once?

It all depends on the size of the battery and its amps. A 40-amp battery can pump out about 2,000 gallons of water per hour for 48 hours. Some batteries last for up to 12 hours, depending on the amount of water that needs to be drained out.

Do I Need A Plumber To Set Up A Battery Backup Sump Pump?
