Client Critiques

So I will be honest right here. Like all pumps in this price tag 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 common for the price tag. Deciding on which pump to get comes down to which distinct design and features do you favor considering the fact that most in this cost range have similar flow rates and various even appear like. You also have to have to consider a bigger pump if you need to have to raise the water even more than about ten feet high.
Most of the construction is plastic such as the impeller itself so do not try pumping anything except clean water as a little rock or pebble would not be fine for it. The circuit board layout and construction is just adequate, for instance it runs fairly hot when charging the battery. Also, the pump itself is not sturdy adequate in some circumstances as I will explain beneath.
I observed that the internal pump relay mounted on the circuit board is quite smaller and rated at 10 amps max. That is not a beneficial sign considering the fact that the pump draws more than 20 amps at startup and settles down to eight.7 amps even though operating. So I would not anticipate a ten amp relay to final a lengthy time when operated near max load like that.
Thinking of how low-cost 20 amp relays are I wish they'd used a greater rated one.
Like most in this price tag range, there are no genuine strain reliefs to defend the wires and the AC transformer is the old style "brick" type with no voltage regulation and not considerably power (700mA trickle charge). That's why it says to enable up to four days to charge the battery. The plastic bottom of the pump has several sharp edges, and the 1" barbed pump outlet is not as valuable or straightforward to service as a typical 1" or 1.five" threaded connection. 1" also appears a bit little for a sump pump so that might limit the flow somewhat. Those items are typical at this value point and there was only one deal breaker as noted beneath
I have 9 foot ceilings in my basement and it's merely not robust sufficient to pump water out of the sump pit. It slowly pumps the very 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 some) then it stalls out and can't lift any way more. It was in fact losing ground soon after a whilst as the pit was slowly filling up (with the pump nevertheless on) as ground water was slowly coming in from the drain tile at about 1 gpm. The motor keeps operating with water sloshing around but it can't do it. So I employed my complete size AC sump pump to pump it out, which takes about 15 seconds to empty the complete sump pit.
The ESP15 has a 25 second timer that shuts off the pump so even if it could lift water high adequate (such as with a 7 -eight foot ceiling) it occasions out ahead of it is performed in my setup. Once began, the timer stays on if there is water present or not so the pump may run dry in some instances. Apparently this is ok by design given that 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 cannot lift that high even with a totally charged battery running at 12.8V DC.
As an experiment I attempted feeding the motor directly with a slightly higher input of 13 Volts DC implementing a precision regulated DC power provide with plenty of current capacity. The outcome was the similar as employing the 12V battery.
Like most pumps it has a lot of flow when not lifting as well far but the 720 gph rating at 10 foot of lift looks optimistic from actual observations. Every corner in a water pipe causes some loss of throughput so perhaps their 10' lift spec is for a straight pipe with no corners rather than a typical household installation.
If you have a lower ceilings or a lower total lift height then this unit can perform fine for you, but I will have to go with a stronger and more high priced pump to operate with a greater ceiling.

UPDATE: 5-4-2011
I bought the bigger Wayne ESP25 rather and that's a lot far better pump. It has at least 4x the flow at ten foot of lift and takes the exact same power as the smaller pump. It really is also quiet and uses a larger 30 amp relay vs the undersized ten amp one particular utilized in the ESP15. The manage box still runs a bit hot when initially charging the battery but at least now it is a complete two amp charger that gets done a lot more quickly than the (700mA) 1 in the ESP15. It really is a smart charger and it settles down to a single DC pulse each 10 seconds or so right after the battery is charged. That is just to keep the battery level, so it runs cool most of the time.
The ESP25 is a taller pump with a lot far more capacity but the actual DC existing draw is about the exact same as the smaller ESP15. So clearly it is a lot more effective style and that is a really good notion when employed as a backup pump.
I measured 9.5 - 10 amps existing draw from the ESP25 whilst lifting water up about 10 feet high by means of 30 feet of pipe overall ....so essentially, I will get a lot way more water pumped per charge from the huge pump considering the fact that it pumps 4x quicker and then it shuts back off whilst the smaller ESP15 just ran and ran.
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 am attempting to be clear and short but it really is not that rather simple).
In my setup it takes 15 seconds to empty the pit with the stronger ESP25 pump. So that is 15 seconds ON time x four occasions per hour which is 1 minute total ON time per hour. Making use of the medium size 40 amp battery I have four hours total ON time to work with (40 amp-hr battery/ten amp load = 4 hours). With 1 minute ON time per hour - the four hour run time should final for days due to the fact it's off 98% of the time.
It functions out to be 240 hours of standby time if the pump is on 1 minute per hour, every single hour.
The Math need to be valid but I will test it sometime and see how numerous hours it holds out.
Your setup and timing may perhaps be various so adjust the math as necessary, for me this setup worked out superb.
The ESP25 fees more but it looks like the preferred selection. It's a lot stronger and alot more effective pump than the smaller ESP15. It also charges faster and runs a lot longer per charge because it's off most of the time simply because it pumps quick and shuts back off appropriate away.

Bought 1 of these and it installed hassle-free enough. The charging unit lasted a single year and two months, just in time to fail for the spring thaws and rains. Tried email correspondence per their webpage to acquire just that piece and was told to contact the 1-800 number that there was testing I needed to do. Sat on hold for 45 minutes, at my perform, on manufacturer client service line and contact was not answered. The line is not attainable right after 6PM EST so calling from residence is not an selection. Tried email again to buy the charging unit and once more referred to buyer service line.
Yanked it out and replaced it with a single from a further manufacturer. I have to have peace of thoughts to know my finised basement will not be ruined.
