Size Name: 1750 Gallons Per Hour
So I'll be honest here. Like all pumps in this price range the EPS15 is not "professional grade" like the ad says. (Note the ESP25 is a lot stronger pump).

The EPS15 is mostly plastic and average for the price. Selecting which pump to get comes down to which particular design and features do you prefer since most in this price range have similar flow rates and many even look like. You also need to consider a bigger pump if you need to raise the water more than about 9 feet high.

Most of the construction is plastic including the impeller itself so don't try pumping anything except clean water as a small rock or pebble would not be good for it. The circuit board layout and construction is just adequate, for example it runs pretty hot when charging the battery. Also, the pump itself is not strong enough in some cases as I'll explain below.

I observed that the internal pump relay mounted on the circuit board is pretty small and rated at 10 amps max. That's not a good sign since the pump draws over 20 amps at startup and settles down to 8.7 amps while running. So I wouldn't expect a 10 amp relay to last a long time when operated near max load like that.
Considering how cheap 20 amp relays are I wish they'd used a higher rated one.

Like most in this price range, there are no real strain reliefs to protect the wires and the AC transformer is the old style "brick" type with no voltage regulation and not much power (700mA trickle charge). That's why it says to allow up to 4 days to charge the battery. The plastic bottom of the pump has many sharp edges, and the 1" barbed pump outlet is not as useful or easy to service as a standard 1" or 1.5" threaded connection. 1" also seems a bit small for a sump pump so that may limit the flow somewhat.

I choose the Wayne because of the poor reviews I found regarding the Basement Watchdog and I'm glad (So far) that I did. Easy straight forward install, just keep in mind the added cost of a battery and acid (Cost me $123 for the battery and $18 for the acid at Lowes. Also $9 for the valve). This unit does not monitor the battery acid/water levels like the BW, but it appears to have a more heavy duty and better built pump then the BW. On another note, the first one I received had a USED control panel (In a NEW sealed product). I returned it with no issues and thankfully the second one did not have this issue.

If you want a reasonable solution to occasional, brief power outages, or perhaps a little peace of mind for a finished basement where a little water might be a big problem, this is an excellent product, especially if you are not the sort of person who would think to rig up something like this for yourself. While it's quite expensive for what it is (a plastic battery case, a chintzy but serviceable charge controller and AC adapter, a and a DC sump pump with a float switch), it is definitely of reasonable quality and if paired with a decent battery will do the job. But with that said, you are paying for the convenience of not assembling these parts yourself, and these parts are not exactly the cream of the crop. The battery housing is not sealed, meaning it serves little purpose besides hiding the battery, providing some protection from drips, and keeping the wiring neat. It also limits your battery choices to one form factor (albeit a common one). The pump is fine but is mostly plastic, I do not expect this pump to last nearly as long as the cast-base AC pump that is my primary. The charge controller is a little stamped-circuit affair that makes a $50 Battery Tender Plus look downright industrial-strength.

As to actual real-world function, my reviews are mixed. Having a second sump of any sort is just smart, and in situations where my primary pump is running but overwhelmed this seems to help quite a bit. Whether 3330 gph is sufficient in a situation when this is the one and only pump will obviously vary from house to house, but for me that is typically enough to keep up. So in a power-on situation where pump #1 failed, this guy would serve me wonderfully, but of course a higher-quality AC pump with more capacity would do even better and cost half as much.

Size Name: 3300 Gallons Per Hour
I just installed the Wayne ESP25 battery sump pump as a backup to my electric driven main pump. I have about a 12 ft rise and I have both tied in to a single pipe that exits the basement. I installed a check valve at the discharge of the ESP25 pump.

After getting everything all set up, I tested the unit. Turned off the main and waited for the float switch to start the pump. It started, but the level in my pit kept rising. Battery was fully charged. I tried it again, this time going outside to see if anything was being pumped. Nothing coming out and I'm positive there was no blockage.

I removed the ESP25 pump from the pit and removed the 7 screws holding the bottom screen and impeller cover. I tried to push on the impeller (assuming an interference with its cover). Without reinstalling the screen and cover, I connected it back up to the battery and triggered the switch. The impeller turned freely. I disconnected power, reinstalled the cover and screen and applied power again. I could not see the impeller turn, but it seemed to be drawing in air through the screen. I did this for a few seconds - I don't think you want to run the pump dry for much longer. I reinstalled the pump in the pit and tested it again. It worked and worked well. There must have been some type of interference that did not allow the impeller to spin freely with the pump out of the box. Something I did by removing the screen and cover freed it up.

My advice is to thoroughly check the pump operation after installation. You don't want to find out there is a problem after the electric goes out.

Also, after putting my battery on the included charger, I noticed a higher reading on my carbon monoxide detector upstairs (up to 10 ppm).
