Sump Pumps/Battery Back-Up Pumps
The most common water pump. Sump pumps are automatic pumps used to remove ground water from sump pits and transfer basement drainage to prevent residential flooding.
Battery Back-Up Sump Pumps are added in addition to your primary sump, and are powered off a 12 Volt battery. This completes your sump pump system and provides additional protection to remove ground water during a power outage, primary pump failure or heavy rain.

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. Those items are typical at this price point and there was only one deal breaker as noted below
I have 9 foot ceilings in my basement and it's simply not strong enough to pump water out of the sump pit. It slowly pumps the first couple inches of water when the pit is over full but as the water level goes down (and the total lift height goes up) then it stalls out and can't lift any more. It was losing ground after a while as water was slowly coming in from the drain tile at about 1 gpm. So I used my full size AC sump pump to pump it out, which takes about 15 seconds to empty the full sump pit.
The ESP15 has a 25 second timer that shuts off the pump so even if it could lift water high enough (such as with a 7 -8 foot ceiling) it times out before it's done in my setup. Once started, the timer stays on whether there is water present or not so the pump may run dry in some cases. Apparently this is ok by design since the timer is not adjustable.
The total lift height in my installation is 10' 6" from the pump inlet up to the highest point and it just can't lift that high even with a fully charged battery running at 12.8V DC.
As an experiment I tried feeding the motor directly with a slightly higher input of 13 Volts DC using a precision regulated DC power supply with plenty of current capacity. The EPS15 ran a little faster but it still couldn't do it.
Like most pumps it has a lot of flow when not lifting too far but the 720 gph rating at 10 foot of lift looks optimistic from actual observations.
If you have a lower ceilings or a lower total lift height then this unit may work fine for you, but I'll have to go with a stronger and more expensive pump to work with a higher ceiling.
I bought the larger Wayne ESP25 instead and that's a lot better pump. It has at least 4x the flow at 10 foot of lift and takes the same power as the smaller pump. It's also quiet and uses a larger 30 amp relay vs the undersized 10 amp one used in the ESP15. The control box still runs a bit hot when initially charging the battery but at least now it's a full 2 amp charger that gets done a lot faster than the (700mA) one in the ESP15. It's a smart charger and it settles down to a single DC pulse every 10 seconds or so after the battery is charged. That's just to maintain the battery level, so it runs cool most of the time.
The ESP25 is a taller pump with a lot more capacity while the actual DC current draw is about the same as the smaller pump. It's a lot more efficient design and that's a good idea when used as a backup pump.
I measured ~ 10 amps current draw from the ESP25 while lifting water up about 10 feet high through 30 feet of pipe.
I'll get a lot more water pumped per charge from the big pump since it pumps 4x faster and shuts back off while the smaller ESP15 just ran and ran trying to do it.
The ESP25 draws about 40mA to run the electronics when in standby mode. At that rate the battery would last for weeks so the only thing that will draw the battery down is the pump itself.
Run-time Calculations: (I'm trying to be clear and brief but it's not that simple).
In my setup it takes 15 seconds to empty the pit with the stronger ESP25 pump. So that's 15 seconds ON time x 4 times per hour which is 1 minute total ON time per hour. Using the medium size 40 amp battery I have 4 hours total ON time to work with (40 amp-hr battery/10 amp load = 4 hours). With 1 minute ON time per hour - the 4 hour run time should last for days since it's off 98% of the time.
It works out to be 240 hours of standby time if the pump is on 1 minute per hour, every hour.
The Math should be valid but your setup and timing may be different so adjust the math as needed, for me this setup worked great.
The ESP25 costs more but it looks like the best choice. It's a lot stronger and more efficient pump than the smaller ESP15. It also charges faster and runs a lot longer per charge since it's off most of the time because it pumps fast and shuts off.
Update 11-2014 ***********
The original Wayne 40 amp-hr 12V battery failed after 3 years. The box says it's a high quality 10 year rated battery (with a 1 yr warranty) but even though it only came on once in 3 years the battery failed totally. The Wayne battery no longer has enough power to run the pump. I mentioned the battery within the sump pump review because both the EPS15 and EPS25 pump need full battery voltage of 12.5V DC or higher to be able to pump much. At 12V even the larger EPS25 can not pump strong enough to empty the sump even 1 time. They really must have 12.5 - 13V for it to pump anywhere near their rated capacity. So when the battery dropped to 12V it didn't move any water.
So... if I had to start over I would get a more powerful pump than either the EPS15 or the EPS25. Neither one can pump much at 10ft of height without a large battery sitting fully charged and at 100% capacity. Most other common DC backup pumps are not any better. If I find a great solution I'll let you know.
I replaced the failed Wayne battery with a full size 95 amp-hr Farm Fleet deep cycle battery and I'm back in business. Farm Fleet batteries cost much less, have higher capacity, and they usually last longer than 3 years.
For this unit, I ordered a large Vmaxtanks 120ah AGM Marine battery with this and it fits perfectly into the plastic case that comes with the pump. The box measures 14" L x 9" H x 9" D. The wiring hookup is easy. There are 3 very different plug in connectors that you cannot connect improperly.
The directions say to use 2 separate discharge pipes but it's ironic that the Wayne dual pump combination doesn't use two. No big deal though. I connected the 12 volt backup pump to a new Wayne 3/4HP 120 volt primary pump with a "Y" PVC connector then to a single discharge pipe through a quick disconnect screw on type fitting. It's a 2" PVC pipe so there won't be any flow problem.
I used PVC pipes for all of the connections except one. Since the 2 pumps were going to be a tight fit I'd have to be able to turn them slightly so I used a rubber (Fernco) fitting on the backup pump. I also did NOT put the check valves 3' up the discharge pipe as the directions suggested. If you put the check valves up that high you're allowing 3' of water to return back to the pit every time the pump stops and that causes valve thumping. I used 2 check valves from Lowes that have threads right on the bottom of the valves. They screw right into the pump bases (I used some silicone grease to lubricate the threads so they won't seize up). The outlet side of the valve fits a 1 1/2 PVC coupling sleeve but that's where I used the Fernco rubber fitting. This way, for maintenance or if either pump quits, I can simply unscrew that fitting instead of cutting the PVC pipe.
After everything was glued and set up I lowered the unit into the sump pit but the pumps wouldn't sit on the bottom. My sump pit is 25" deep by 18" across but, because of the Fernco fitting, I was able to turn the backup pump slightly and they both sat on the bottom nicely.
Now for my 3 gripes (Wayne fails to address them in the product description):
The backup pump's float switch is not like the typical ones. This one only turns a timer on. The pump then runs for 20 seconds and this cannot be changed. It can be a problem if your pit isn't deep enough or if the float isn't mounted high enough. If either of those situations are true, the pump will empty the pit and keep running until the 20 seconds are up. WAYNE; THERE SHOULD HAVE BEEN SOME TYPE OF ADJUSTMENT ON THE CIRCUIT BOARD FOR THIS! I'm an electronics wiz so maybe I'll look into which resistor causes the 20 second run time and change it out to an adjustable one. (Any help with this Wayne)???
Second; I have a small electric FM radio on my desk and the circuit board in the battery cover blankets it out completely. I had to relocate the battery box onto the floor behind me to be able to hear my radio! WAYNE; USE SOME SHIELDING ON THE CURCUITRY & WIRING!
Finally that irritating alarm! It does go off after @ 20 seconds but it needs a volume control! Being an electronics wiz, I solved the problem w/o doing any damage. I removed the 3 small screws that hold the circuit board onto the cover and found the little demon. There's a tiny hole in the gray plastic cover of the circuit board speaker. I GENTLY put a small piece of tissue into the hole and it quiets it down nicely. DO NOT put the tissue in more than 1/16 of an inch or you'll damage the tiny speaker.
One more thing (not a gripe) is the charger itself. This is a heavy unit. It will not stay plugged into most electric outlets. I ended up using a small extension cord and laid in on the floor and it works fine.
Now that all the demons have been dealt with, it's really a nice unit. To test the backup pump, I simply didn't plug in the 120 volt main pump and I guestimated where I should put the float switch then I let the pit fill up. The backup pump ran quietly for exactly 20 seconds but the pit was emptied in 18. Not a bad guess, eh? Then I plugged in the main pump and it worked flawlessly and very quietly! Hope this helps someone.
