What is a Heavy Duty Backup Sump Pump?

A Heavy Duty Backup System is 2 sump pumps And Auxiliary Power InverterJust what does Heavy Duty Backup Sump Pump mean?

A heavy duty backup sump pump is a pump that can handle at least as much water per minute as a one-half horse power electric pump and preferably more.
It is a pump that can run when the electricity fails.
It is capable of running continuous for long periods of time without overheating.
It is heavy enough to remain stationary in the basin while pumping so the switch does not get caught on the basin wall and cause the pump to fail.
It operates automatically without human intervention.
 

Who is a Heavy Duty Backup Sump Pump For?

A heavy duty backup sump pump is for those who get a lot of heavy rain storms and know the electricity may go out or the primary pump may fail during such storms. It is for those who live in constant fear of a flooded basement. That was us.

The Fear Of A Flooded Basement

A Flooded basement causes loss of personal property, mold treat and clean up takes hoursThe fear of a flooded basement is real and so are the effects. Flooded basements can develop musty mold and certainly ruin personal belongings.

Many years ago before we installed a power inverter and an extra sump basin, we panicked every time it rained and double panicked when the electricity went out during a heavy rainstorm. We would sleep in the basement with our 5 gallon pails and flashlights ready for action. We still remember the time when the basin was just ready to overflow because the backup pump could not keep up and then the electricity can on. We felt 30 years younger.

It was that event that caused us to take action so we would never have to live in fear again when buckets of rain came.

 
 
 

What Is The Battery Backup Sump Pump That Pumps The Most Water Per Hour?

There are two types of backup sump pumps on the market: the battery backup sump pump and the water powered sump pump. Both types are reviewed for their pumping capability.

Most Powerful Battery Backup Systems but  cannot pump as much as one-half horse power pumpThe most powerful battery backup sump pumps are these three.

- The Zoeller Aquanot Fit 508 which pumps 34 GPM and 2,090 GPH at a ten foot vertical height
- The Zoeller Pedestal battery backup 585 which pumps at 36 GPM and 2,100 GPH
- The Basement Watchdog Big Dog which pumps 35 PGM and 2,200 GPH at a 10 foot vertical height.
 

The rest of the most popular battery backup sump pumps cannot even pump as much as a one-third horse power pump.These battery backup sump pumps are the following.

- The Liberty Pumps Model 441 at 1,740 GPH
- The Glentronics Pro Series 2400 at 1,380 GPH
- The Wayne ESP25n at 1,500 GPH
- The Little Giant SPBS-10HF-6 at 1,200 GPH and the Little Giant SPBS-12HF-10 at 1,440 GPH
- The Superior Pump 92-900 and 92910 at 1,080 GPH.
 

The following two battery backup sump pumps can pump a lot of water, but they are no longer available for being made. the Wayne ESP45 which pumps at 40 GPM and 2,400 GPH at a ten foot vertical height the Hydro pump DH1800 which pumps at 44 GPM and 2,680 GPH.

The Bottom Line
None of the battery backup sump pumps are capable of pumping as much water as a primary submersible sump pump and therefore cannot be called heavy duty backup sump pumps.

What Is The Water Powered Backup Sump Pump That Pumps The Most Water Per Hour?

Most Powerful Water Powered Sump Pumps cannot pump as much as one-half horse power pumpWater powered backup pumps are talked about a lot today and recommended by plumbers, so we checked them out. We were very disappointed. Even the best water powered backup pumps cannot pump as much as a one-half horse power primary sump pump.

Here are the most powerful water powered sump pumps.

- The Zoeller 540 Flex pumps at 1,140 GPH at 60 PSI (pounds per square inch)
- The Liberty SJ10 Sump Jet at 960 GPH
- The Basepump HB1000 at 1,000 GPH and the Basepump CB1500 at 1,500 GPH.
 
The Bottom Line
The best water powered sump pumps provide even less pumping capability than the battery backup pumps, so they definitely do not qualify as a heavy duty backup sump pump.
 

So what is a home owner who has more than 2,000 gallons of water entering the sump basin during a heavy rainstorm to do?

We continued to look for a solution. Then finally we found a heavy duty backup sump pump system solution that works.

 
 
 

Our Discovery - A Heavy Duty Backup Sump Pump System

The Sumpro 75 is The Heavy Duty Backup Pump System We installed in 2004 and it works perfectly. We just install new batteries every 5 - 7 years and that is it. We discovered the Sumpro 75 Power Inverter and installed it in 2004 without incident. The Sumpro Model 75 uses two batteries and can run a 3/4 HP or 1 HP electric pump as long as the pump requires less than 15 amps which most electric driven sump pumps do.

The Sumpro is very dependable and the only maintenance required is two new batteries every 5 to 10 years.

Four years ago when we had a 7 inch rainstorm in 2 days we were so glad we had a Sumpro installed because the amount of water to be pumped took 4 sump pumps. One of our pumps failed but we were prepared for the worst and our basement did not flood. The Sumpro power inverter ran our one-half horse power primary pump which is much more durable and powerful. Our basement is completely finished so the amount we invested in the Sumpro is so much less than the cost of losing personal belongs and remediating a flooded basement. Even flood insurance is more expensive.

The following information explains how the Sumpro power inverter works, how it is installed and what sump pumps can be used with it.

Learning about the Sumpro will provide a great understanding of the other power inverter brands we include below because they operate the same way.

What Is The Sumpro - Models 75 And 100?

Here Is What The Sumpro Or Any Auxiliary Power Unit is.

- It is an alternative to a generator and is certainly better than a portable generator because it gives off no fumes and is fully automated.
- They are power converters because they invert DC power (battery power) of two 120 amp deep cycle marine batteries and convert it to electrical power (AC). It is the converted AC power that runs the electric sump pump.
- They are emergency power systems. They run when the wall socket electricity fails. The Sumpro 75 and Sumpro 100 provide up to 1800 watts of electricity that can support a 15 amp electrical sump pump for 3 1/2 hours of continuous run time. Sumpro offers a three year warranty.
 

What Are The Major Components Of The Sumpro - Models 75 And 100?

The Sumpro Model 100  Six Key ComponentsThere are six major components to a power inverter.

- There is a power head which converts the battery power into electrical power and provides enough watts to run 3/4 HP and 1 HP electric sump pumps for 3 1/2 continuous hours of run time. It supports a sump pump needing up to 15 AMPS while running and 300 Amps when starting. The power provided is dependable for the entire run time. The power from the Sumpro is only used when the electricity fails because the Sumpro plugs into a wall outlet.
- There are two 16 gauge steel boxes attached together when installed. One of the steel boxes is the power head and the other steel box houses the two batteries. It is possible to purchase another steel box to house two more additional batteries as well.
- There is a transfer switch found in the power head to sense when electrical power is absent and automatically switches to usage of the converted battery power so anything plugged into it operates off of the converted power.
- There is a 40 amp charger to recharge the batteries. Recharging may take 6 - 8 hours. Compared to other manufacturer's battery backup sump pump systems, Sumpro's charger is faster than other brands. Some brands use a .2 charger which can take up to 3 days to completely charge a depleted battery.
- The unit has an electrical power plug that is plugged into a wall socket. Electricity (AC) power is used until it is not available.
- LCD screen for real-time monitoring.
 
 
 

How does the Sumpro Power Inverter Work?

- The Sumpro power cord is plugged into a wall socket. This gives power to the adapter which keeps the two deep cycle marine batteries charged with DC power and ready for use.
- The two batteries found in the battery case are linked together and one of the batteries is linked to the Sumpro power head. The electric sump pump is plugged into the Sumpro power head outlet.
- Once a power failure is detected, the Sumpro transfer switch instantly switches the pump to use the power stored in the batteries and converted by the power head from DC to AC to supply standard household electricity to the sump pump. Once utility wall outlet power is restored, the Sumpro transfer switch automatically switches the sump pump back to wall outlet power and the Sumpro internal batteries are recharged in anticipation of the next power failure.
- The Sumpro system works seamlessly and provides notification by means of a charge light when the batteries need to be replaced. Ours has been installed since 2004 and works perfectly. Every 5 to 9 years the two batteries need to be replaced.

How To Install the Sumpro Model 75 and Sumpro 100

The Sumpro Model 100  Typical InstallationThe Sumpro Model 75 and Sumpro 100 are easy to install.

No additional piping or wiring is required; however a dedicated wall socket is necessary.

The power head and the battery box should be placed on a heavy duty stand since the unit weighs around 100 pounds. 2x4 studs make a good, strong stand.

When installing, place the sumpro unit on the stand. Face the front of the unit and proceed with the following steps.

1) Place the batteries in the battery box so that the left battery terminal is the positive, and the right negative.
2) Connect the fuse plate across the back battery terminals.
3) Connect the negative (-) battery lead (black) to the negative (-) post of the battery.
4) Screw down the bolt tightly.
5) Plug the Sumpro unit into the designated wall socket AC outlet. Within 30 seconds, connect the positive ( ) red battery lead (red) to the positive ( ) post of the front battery.
6) Close and secure the battery enclosure lid.
7) Plug the pump into the Sumpro power head socket.

What Heavy Duty Primary Sump Pumps Work With The Sumpro 75 And Sumpro 100 (Or Any Power Inverter With 1800 Watts Of Current)?

Any primary submersible or pedestal sump pump can be used with the Sumpro 75 or Model 100 also long as they use 15 amps or less. The manufacturer's manual will indicate how many amps are used for your installed primary sump pump. There are many options for the homeowner.

Here are some of the heavy duty sump pump options.

- The Zoeller M95, M98, M137 and M139, one-half horse power pumps, require 10.7 amps or less.
- The Wayne CDU1000, a one horse power pump, requires 11 amps. The Wayne CDU980E, a ¾ horse power pump, requires less than 11 amps.
- The Liberty Pumps 290 Series, ¾ horse power pumps, require 10.4 amps.
- The Little Giant Pumps 10EC and 12E, ½ horse power pumps, require 9 amps and 10 amps respectively.
- The Flotec E75VLT, ¾ horse power pump, requires 6.3 amps.
- The Ridgid SP-1000, one horse power, requires 9.8 amps.
 
The lower the amp usage, the longer the converted DC power to AD power will last. A 7 amp sump pump could pump for about 5 continous pumping hours.
 
 
 

What Is The Pumping Capacity Of The Above Listed Heavy Duty Primary Sump Pumps?

- The Zoeller M95 pumps 3,960 GPH at a 10 foot vertical height, M98 is 3,660 GPH, and for M137 and M139 it is 4,740 GPH.
- The Wayne CDU1000 pumps 5,400 GPH at a 10 foot vertical height and for CDU980E it is 4,600 GPH.
- The Liberty Pumps 290 Series pumps 4,350 GPH at a 10 foot vertical height.
- The Little Giant Pumps 10EC pumps 3,300 GPH at a 10 foot vertical height, and for 12E it is 2,880 GPH.
- The Flotec E75VLT pumps 4,020 GPH at a 10 foot vertical height.
- The Ridgid SP-1000 pumps 4,200 GPH at a 10 foot vertical height.

What Customer Reviews Say About Sumpro

 
It works good
By Paul Simpson, Illinois July 5, 2020

I was leery of buying the Sumpro because I thought converting DC to AC was wasting too much power. But I had the dilemma that I needed a heavy duty backup sump pump. I bought the Sumpro. It does work. I have a 3/4 HP primary pump plugged into it. It has never had to run over 1 hour when the electricity was out. It ran my pump just fine. Just listening to it as my pump ran on its power made me feel that it is very dependable. I am glad I bought it now.

Sumpro is well worth the cost
By Terry, Indiana, April 2, 2021

The Sumpro is very pricey. However, since I bought it I have talked with several plumbers and they say only good things about it. Plumbers highly recommend it. I needed a heavy duty backup system. This is a good unit.

Good and easy to install
By Bob Greene, Minnesota, May 16, 2021

I read the manual and decided to install the Sumpro myself. It was easy to install. I already had a dedicated wall socket. The unit is very heavy, but since the power head and battery box came unattached I was able to handle it. I set the battery box and power head on a stand I made from 2x4's. I made the stand high enough so I could easily access it for battery service. I put the batteries in the heavy duty battery box, hooked up the cables, plugged the Sumpro in, plugged my electrical sump pump into the Sumpro and that was about it. I am glad I bought it. Now I can have peace of mind that I have a powerful enough sump pump to keep up with the water flowing into our sump pit if the electric power goes out when the heavy rains come.

Owned a Sumpro for 10 years
By Mr. Plumber, Des Plaines, IL, May 20, 2021

I can say that the Sumpro is a great unit. I purchased it 10 years ago and it is still functioning very well. This is a very effective solution for someone who has heavy rainfall when the electricity fails. It has been used seven times during the past 10o years. It runs so well with my 3/4 HP primary electric sump pump. As a plumber I highly recommend this backup system solution.

Great backup pump solution
By Jeff, Minnesota, June 20, 2021

The Sumpro works flawlessly. It has a great charging system and provides me peace of mind. Initially I bought AGM batteries. They did not last long and cost a lot. Now I use cheaper 120 amp deep cycle batteries that require my adding distilled water every few months. My 3/4 HP sump pump is plugged into it. When utility electrical power is available my pump uses the utility electrical power; however when utility electricity fails, the transfer switch automatically switches the electrical sump pump to start automatically. This is a powerful, great backup system.
