Wayne ESP25 and ESP45 key features and specification differences

ESP45 pumps at 2400 gph at a 10 foot lift or 40 gpm while the ESP25 pumps at 2300 gph at a 10 foot lift or 38 gpm. At a 15 foot lift the ESP45 pumps 1750 gph and the ESP25 pumps 1500 gph.

Construction Material Used 
Longer life can be expected from the Wayne ESP45 since it is made from cast iron. The ESP25 is made from thermoplastic. A cast iron pump will last longer.

Efficiency is most evident in the Wayne ESP45. Its finned motor housing reduces heat in the DC motor for increased life. Its motor and hydrological design also increases its pumping performance. The Wayne ESP25 housing is solid and cylindrical.

Impeller Jamming
Impeller jamming is least likely to happen with the Wayne ESP45 since it has a top suction design. The impeller is not at the basin bottom like it is for the Wayne ESP25. The top suction design also prevents air lock and thus no weep hole is needed. The Wayne ESP25 does not have these features.

Battery Power Required
The Wayne ESP45 requires two deep-cycle marine batteries to operate; thus is called a 24-volt backup pump. On the other hand the ESP25 requireds one deep-cycle marine battery to operate and is called a 12 volt backup pump. Two batteries are required for the ESP45 since it has a greater pumping capability. It is also possible to double the pumping run time for the ESP45 by adding two additional batteries.

Versatility is more prevalent with the Wayne ESP45. The ideal backup pump to own is one that runs on AC (electrical power) when the electricty is on and DC (battery power) when the electricity is off.

The Wayne ESP45 will run on both AC and DC. The Wayne ESP25 will only run on DC power.

It is also possible to add an additional 2 batteries to the ESP45 to increase pump run time.

Dimensions and Weight
Pump weight also impacts how reliable a backup pump is. The Wayne ESP45 weighs 30 pounds whereas the ESP25 weighs only 20 pounds. The ESP45 is 8 3/4 inches in diameter. The ESP25 is 8 1/4 inches in diameter.

The warranty is longer for the Wayne ESP45. Three years verses 2 years for the ESP25.

What are the key features of similarity?
Both battery backup pumps use a magnetic reed style float switch. The magnetic reed style
float switch is much more reliable since the dry reed switch is enclosed within a stem. The switch will open on the rise of water and close on the fall of water.

The alarm notification system is the same for both backup pumps. An alarm lets the homeowner know when the pump is operating, and when there is low voltage or a blown fuse.

The power cord length is 10 feet. There is not built-in check valve. The discharge port size is 1 1/2 inches. There is no manual override.

Both are manufactured in the United States.

Which is the best battery backup sump pump for your pumping needs?

What is the size of your existing primary sump pump?
If it is 1/3 HP the Wayne ESP25 will be sufficient. If your main pump is 1/2 HP, the Wayne ESP45 will meet your pumping needs.

Is material used for pump housing important? The Wayne ESP45 is most durable made from cast iron.

Are you concerned about warranty period? The Wayne ESP45 has a three year warranty while the ESP25 has a two year warranty.

Are you more concerned about pumping capability? The Wayne ESP25 will pump 2300 gph at a 10 foot lift while the Wayne ESP45 will pump 2400 gph.

Are you concerned about impeller clogging? The ESP45 is built with top suction which limits impeller clogging from sludge.

Wayne ESP25 and ESP45 Customer Reviews 

Wayne ESP25 Backup Sump Pump Customer Reviews
Wayne ESP25 better pump
By Ted White, Ohio May 20, 2011
I bought a Wayne ESP25 after owning a Wayne ESP15.  It%u2019s a larger and much better pump. It pumps at least three times as much at a 10 foot of lift.

It is a quiet pump. It has a stronger battery charger %u2013 2 amps %u2013 compared to the .7 amp of the ESP15. Even though the ESP25 is a taller pump, its more efficient since the DC current it draws is about the same as the ESP15. It has about a 10 amp draw at a 10 foot lift through 25 feet of discharge pipe. It pumps a lot more water per charge so it shuts off between pumps whereas the ESP15 just kept running.
This system does not draw much battery power in standby mode. I think it is around 40mA; Wayne calls it a trickle charge. Really the only thing that draws the battery down
is the pump itself.

Easy to install
By Mike, Illinois, April 5, 2011
The Wayne ESP25 is very easy to install and it is small enough to fit beside my A/C pump in an 18 inch diameter sump pit. The float switch attaches to the discharge pipe so
doesn%u2019t take any additional pit room. I set the float level to activate when the water gets 1 inch higher than when my main pump float switch activates. So far so good.

Well Built
By Tom, St. Louis, MO, March 22, 2011
I have had other brands of backup pumps. The Wayne ESP25 appears to be better built with more heavy duty pumping. I installed a battery that requires adding water to periodically. I should have installed a sealed lead-acid maintenance free battery since this system does not let me know when I need to add distilled water.

Test It
By George Stevens, Minnesota, March 10, 2011
I just installed the Wayne ESP25 battery sump pump. It was easy to install. I tested it, but at first it did not do anything. I could not find any blockage anywhere so I checked the pump out. Somehow the impeller did not seem to work. I took off the bottom screen and impeller cover and got the impeller to move freely. I reinstalled the pump in the pit and
tested it again. It worked and worked well. What ever it was the pump is working fine now. It was so important to check out the pump to see if it was working before I needed it to

Good Buy for the Money
By Plumber, Springfield. October 10, 2010
I am a plumber and would recommend this pump. It is a good buy and very easy to install. It pumps a lot of water.

Wayne Name Brand Pump Manufacturer
By Jim Schroeder, Illinois, September 9, 2011
I wanted a pump from a name brand manufacturer. Wayne is it. They are made in the United States. The ESP25 was easy to install. I tested it and it works. No power failure but I
test it once a month. I expect that it will run problem free for many years.

Installation was easy
By Tmac, August 25, 2010
I never installed a pump before, but thought I would give it a try since the Wayne install manual seemed easy. Things were going well. Like the manual said, I unplugged my main
pump. After I had the Wayne ESP25 installed, I forgot to plug in my main pump again. All of the sudden I heard this gush of water. The backup pump was working. I forgot the Wayne system was battery operated. So my first attempt worked. I certainly feel more confident knowing it is in place and ready to work if necessary.

Protection for our finished basement
By Brad Brockman, Illinois, June 12, 2010
We have a fully furnished basement with recreation room, bedroom, full bath and freezers. It would be expensive and frustrating to clean up after a flooded basement so I purchased the ESP25 as a backup pump. So far it has protected us twice during a heavy rainstorm.

Wayne ESP25 with sealed battery
By Richard T, Mille Lac, MN, May 25, 2010
I had another brand of backup pump before that monitored the fluid level in the battery. Since the Wayne system does not monitor battery fluid level I purchased a completely
sealed battery. This pump really moves the water. During a recent rainstorm I tested out the ESP25 by unplugging the main pump and letting this pump take over. It kept up with the water with no problems. In fact I let it run for 10 hours. I am happy with this pump and feel that my finished basement is safe now.

Pumps well and easy to install
By Mac, Coon Rapids, MN, April 10, 2010
I checked out several backup pumps online and decided to buy the Wayne ESP25 for its pumping capacity and that it can use a maintenance free battery. It was easy to install
and it pumps like I was hoping.

Wayne ESP45 Backup Sump Pump Customer Reviews
Wayne ESP45 very powerful
By Andrew schooner, Michigan, May 21, 2011
This is a good pump. It has a good charging system and strong battery power with 2 batteries. It works flawlessly. I am getting used to the alarm system. It lets me know
when the pump is in operation. I can silence the alarm for 4 hours and then it sounds again. I guess this is because I need to be reminded that it is running.

Best Pumping
By Brian Hamm, Missouri, April 12, 2011
I purchased a Wayne ESP45 because we get a lot of heavy rain, plus we have a high water table. My main pump float switches fail so I needed a battery backup pump to protect out basement from flooding during those times. This pump pumps as much as a 1/2 hp main pump. I am very happy with it. I feel at ease when taking a vacation during the heavy rains now.

Good Pump for the Price
By Ted Marsh, Wisconsin, March 9, 2010
The Wayne ESP45 is not cheap; however it comparison to other backup systems this pump system is reasonably priced. It has a lot of pumping power. I am surprised at how much water this pumps. This is a good pump. It is made of cast iron.
