How To Choose The Best Backup Pump System

What all things to be kept in mind?

There are many things that need to be thought of before you shop for a backup sump pump. You will need to look out for a number of features like the ones mentioned below:

How To Choose The Best Backup Pump System

1. There are two options that are offered by the market and your job is to understand their differences between them:

Battery Backup Pump:

Here we are talking about the battery backup pump which is the most conventional and battery-operated pump that is kept as a layoff to assist the main basement pump. These packages include a DC-powered auxiliary pump along with a battery. Its installation is done along with the primary pump in the sump pit.

The Plus:

  • The aim of a secondary pump is to provide assistance when there is a rise in water levels beyond the main pump capabilities.

  • The float sensor (secondary pump) is placed above the sensor level on the main pump to achieve redundancy.

The Minus:

  • These work when power goes out but may not match the power of a primary pump.

  • This may cause further problems as they play a support role more. Hence, a smaller battery along with a limited backup will lead to a wet basement despite of your efforts.

Power Converter/Control System:

The other one is the power converter/control system, the sump pump battery back-up which is designed for wall mounting and is used in concurrence with a battery-bank or a battery.

The Plus:

  • This second method is a bit different and does not aim to supplement or replace the main pump’s function.

  • If the power goes out the battery backups tend to continue wholly and operate at their full capacity in case of power outage/electricity failure.

  • No additional pumping equipment required and does not occupy any additional space in the sump pit. They have a long life-span too.

The Minus:

  • In case of a mechanical pump failure and if the pump breaks itself the battery backup may not activate and this is the biggest drawback.

  • Henceforth, both the above two options are available in the market and before making a decision weight the benefits and downsides of both and take into consideration your basement condition too before you buy a sump pump.

Battery Backup Sump Pump

2. Deep cycle V/S AGM Batteries:

The battery type you select is a determining aspect that may affect your decision. We are not saying that there are the best or the worst batteries, but they come different qualities.

Generally these are of two types:

  • Deep cycle marine batteries

  • AGM batteries

  1. The battery backups that use Deep Cycle Marine Batteries tend to require regular maintenance for retaining their charge.

  2. On the other hand the AGM Batteries are not only maintenance-free but can also last up to 50% longer as compared to former.

3. Battery Life:

  • This tends to vary from model to model. Since the batteries can be replaced, as after a particular episode of flood, the replacement can be done later.

  • The time length of any sump pump is decided by the no of hours it works. Even the model type lets you decide as some of these pump faster and consume more power while the water fills quickly. This will let the battery go for a lesser time.

  • If used fairly some of these sump pumps may last for 50 hours when working at maximum capacity. Before the battery runs out most of the battery backup sump pumps will warn you.

Battery Life And Design

4. General Design:

  • This is one of the most crucial factor that needs to be considered.Pumping capacity, output, and current type relates to these things.

  • The standard impeller system designed is possessed by the best sump pumps as these tend to keep all the components sealed properly and safe against moisture or air.

  • Even when the drain pit is filling with water, a good design guarantees functionality while remaining completely submerged.

  • The backup sump pumps can be AC or DC. Both utilize home current and battery according to the availability. The DC are more reasonably priced than the AC types.

5. Performance Rating Of The Pump:

  • The output rating of the primary pump needs to be considered for knowing the performance. Your backup pump should be able to handle successfully everything in case your primary pump fails.

  • The rate of 2100 to 3600 gallons per hour (GPH) is a good one. One should select a backup sump pump that has a pumping capacity which should be greater or similar to what your primary pump delivers.

  • If you are technology lover then you will be happy to know that the new advanced designs come with smart sensors along with wireless internet technology that bring much convenience and ease. How great it is when you can control your backup pump with a mobile device or computer.

6. Materials Used:

This is another potent aspect that can’t be ruled out as the quality of materials used to make a product are directly linked with its durability. There are two major materials used:

  1. Thermoplastic

  2. Cast Iron

 

Though both are good but cast iron is virtually indestructible. This is somewhat thicker than thermoplastic. The handling and tackling should not be bothersome when you maneuver one up-down in your pit.

7. Noise:

  • Though these mini miracles are placed in the basement of your home but may be quite disturbing if noisy.

  • So, selecting a one that makes less noise is always fruitful in future.

Warranty:

A good warranty is something that will always keep you covered and will provide peace of mind. It is wise that if you spend a bit more for a model which offers exceptional warranty.

So before buying be cautious towards the warranty protection aspect and select the best sump pump.

Importance of Sump Pump Battery Backup Systems

Your home is an expensive investment. That’s why preventing water damages from occurring by installing a sump pump battery backup system can save you time, money and can help to extend the lifespan of your home. Here are just a few of the many benefits that a battery backup system for your sump pump will provide you:

Battery Backup Sump Pump System

  • No moving parts to wear out
  • Highest gallon per hour pump capacity
  • Charging system allows for simultaneous charging and pump operation
  • A secondary system prevents water damages during heavy water infiltration seasons
  • Plug and play capabilities – install it and forget it
  • Automatic sensors detect water intrusion and instantly pump away water – even if you’re not home
  • Warning alarms alert you to when the battery needs maintenance

Battery Backup Vs. Generators

1. Generator can serve as a backup for your sump pump as well as your home. But with many sump pump systems, the generator needs to have enough wattage and amperes to provide the sump pump backup power, as it needs to maintain the sump pits water level. A battery backup sump pump will pump away water easily as it uses a secondary sump pump system that is designed for DC power to pump water from the sump pit, eliminating the need to use the primary pump right away.

2. A battery-powered secondary sump pump compared to a generator-powered backup system for your primary sump pump can pump away just as much water as the primary pump, with the exception that you can’t recharge the battery until the power is restored.

Battery Backup Vs. Generator Sump Pump

3. Typical battery for sump pumps will have a run time of around 5-8 hours, while a fuel-powered generator can be refilled as often as necessary to maintain the water level in the sump pit.

Battery Backup Vs Water-Powered Sump Pump

Battery Backup Vs. Water Powered

A water powered sump pump works on water pressure from a municipal water line to create a vacuum that rotates a turbine to pump out the water from the sump pit. Water powered sump pumps can only be used when water pressure exceeds 40 psi.

If you own your own well, then a battery backup sump pump is required to maintain the sump pits water level. Water powered backup sump pump systems cannot be used in conjunction with an electrical powered primary sump pump for obvious electrical safety reasons.

Is it required to install a battery-powered sump pump if I have a backup power source like a generator?

Generators can work as long as their power supply switch is ON whereas a backup sump pump works until is it charged. Undoubtedly, a generator provides huge power needed for a sump pump. However, a backup sump pump is still required to get energy in case of a power failure.

How long will the battery backup last when charged for a single time?

The charge of batteries depend on its size. The batteries having over 40 amp power could be used for 2-3 days used one hour per day. Whereas some batteries last for 10-12 hours based on amount of water it uses to pump.
