WAYNE ESP25 12 Volt Battery Back-Up Sump Pump System with Audible Alarm

Easy to setup, wire-up, and get into place. Was a little-bit of a tight fit with both pumps in my pit, but they fit together facing opposite directions. These pumps are quiet, fast, and after 3 months, reliable. Battery backup has been tested a few times manually, and still seems to work well. I'm very comfortable with the setup. It took about 20-30 minutes total to setup with a Y-joint pipe and check valve cutting a new pipe to join the two, and I zip-tied the float to the pipe and tested with a water pour to be sure it wouldn't snag or hesitate. The battery I used was Casil 100 AH Deep Cycle AGM CA121000 SLA Solar/RV battery for $185, which got top ratings and matched the terminal requirements. I Mated this kit to a Wayne CDU980E 3/4 HP pump using the PumpSpy Dual Pump Install Kit and a Raybend,"Silent" Sump Pump Check Valve, 1-1/2" that I had installed prior to hooking up the backup pump kit. Altogether, I spent about $820-$850, which is much less than the $1800 I was priced for a 1/2, 1/3 HP kit by a local plumber. Between the two pump installs, drilling and mods, and running 3 more drain lines that were never installed originally (Heater, tank, A/C condensation, and Humidifier) it took me about 60-70 minutes for all of the work, testing, and cable dressing. At $860 - $1000/hr for after-tax labor, it was well-worth my time, and surprisingly very easy to do. I may add pics later, if I have the time.Don't bother with the unsealed batteries, and the Li-ion's aren't worth the price, especially, as they cold pose a fire hazard in the humid environment you'll be using them in - unless you know the maker well and can trust the quality of the sealed system - especially since this charging system doesn't have the electronics to protect against surges or overcharging of Li-ion batteries. This system shouldn't go through enough cycles to make it worthwhile anyway. In fact, with the reliable power I have at my house, I really only need a standard 12V car or lawn-tractor battery, but it's worth the comfort of knowing this will last and have the capacity if the power goes out for awhile.

After research, this was our choice for a back-up pump to our Zoeller M53 main pump and, after installation and use, we are happy with it and recommend it.For back-up pumps, it looks like there are 4 choices:- This Wayne pump WSB1275- PumpSpy PS2000- Cheaper, low flow back-ups- Local pumps (eg, Trusty Warns) sold by plumbing companies, costing ~$1400The local pump option was too spendy and there's no logic in buying a back-up pump that is tiny and has low output - the flow rate from the back-up should be similar to the main pump - if the power goes out and the back-up kicks in, it would be a travesty if it can't keep up and water flows out of the bucket.The PumpSpy is a larger pump with higher than typical flow rate (eg, 2400 gph @ 10' head) and it connects to WiFi to and will send an e-mail when it engages. The Wayne pump flow rate (1680 gph @ 10' head) is similar to our good Zoeller M53 pump (2000 gph @ 10' head) but doesn't connect to Wifi. Getting an e-mail when the pump kicks in would be nice but it's not that important to us. And, the over $200 difference between those two pumps is in Wayne's favor.Some things about this Wayne WSB1275 pump:- The float is not attached to the pump and this independence allows for the float to be installed at the right elevation. The pump is on a cord that connects to the controller.- When the float activates the pump, the pump runs for 20 seconds then shuts off. So, the float needs to be installed high enough so the pump runs for about 20 seconds to prevent the pump from running dry. This takes some finagling and trial/error to figure out. Also, it's nice to be able to position the float away from anything it could get stuck on, like the ribbed plastic sump basket or the other pump.- The alarm isn't overly loud and only engages for about 2 seconds when the pump starts. I saw another review where the person said the alarm was too loud. I think it's too quiet and that it should run longer. We can hear it upstairs, just if the furnace fan is running it can drowned out.- I had a large marine battery from my former custom system and was able to use that with this, so that was nice.Overall, I really like it. The pump is solid, the float works well, and it's simple in a nice way.

I decided to get this sump pump one night when it was raining heavy and my current pump was running every 4-5 minutes. (I could hear it from the basement) It was 10 pm and I wondered to myself, ‘what would I do right now if the pump quit at this moment or the power went out?’ I don’t know the age of my old pump as it came with the house when I bought it a few years ago. So I decided to research sump pumps and after reading reviews from customers and professionals, I decided to get this one. It was more expensive than others, but the cost, and headache, of repairing a water damaged basement is so much more. Install was easy. The only thing you have to know, is that they don’t tighten and screws or nuts on the supplied backflow valve. So be sure to check those. Mine was leaking initially until I tightened them up. The unit is amazingly quiet. Even standing over it while it is running, it’s hard to hear it. Other than the sound of water as it’s being pumped through the pipes. I really like having the battery powered backup pump. Sets my mind at ease now when it’s raining, not worrying about a power outage or main pump failure. That alone is worth the price.

First of all....if you are like me you've been trying to find a suitable high volume backup pump that's easy to setup. You've been reading all the reviews on everything that you've been looking at, and you're still not convinced that any of them will do the job. Stop reading the reviews! This pump will do the job and it was very easy to hook up! It's rated for 3300 gph at a 0' lift.....and even at 6' I believe it's still rated for about 2500 gph. I have a 6' lift and this pump empties my sump pit just about as quickly as my regular pump. Hook up was easy.....I needed to buy an inch and half 'Y' connector, a 10' piece of inch and a half pvc pipe and a couple of elbows and connectors along with some of that pvc glue (clearly I am not a plumber because I don't remember the names of most of the stuff but I could recognize the parts in the hardware store. I used a hacksaw to cut the pipe to length, glued I all together and connected the whole system to the battery box in about 2 hours (if I was handy, it should have probably only taken about 45 minutes but I had to think a bit as I went. Yes, I did put a back flow stopper in just above the pump discharge. I paired this pump up with a nice AGM deep cycle battery and by my calculations that should have no problems providing 24-48 hours of backup. The alarm feature of this pump works well and is not annoying. Works like a charm.....spend the money on this system, you won't be disappointed!

Very powerful, sturdy and extremely quiet pump. Preassembled so installation was a snap. I needed a primary and secondary 12 volt pump that would move a lot of water.Fast shipping so that was also a bonus. Highly recommended.

I’ve had this for 2 yrs now, after my basement flooded when my other pump failed. It has been so quiet and so reliable. I put 2 water sensors next to it, but zero problems. I will buy another just for backup, but this is one of the best products I have bought. Came back here after 2 yrs because I had to tell my story. If you’re thinking of buying it, do it. You won’t regret it.

Like a good sump pump story? Read on! Review at the end..After months of debating what to buy, I finally purchased the Wayne backup system. We would be at the cottage over the summer and construction outside left us with a temporary water line (garden hose) pouring water into our ditch. That water eventually ended up as a constant stream into our sump pit. After seeing this, I kindly asked them to move the line. Still had water going in and thought.. well, this seems like a good time to put my backup system in.Easy install, tested and worked great.630am the next morning the power went out for 2hrs! Got it installed JUST IN TIME!Not once, in the six years I’ve lived here, has the power gone out while water was pouring into the well. Not once. I installed the backup system and the very next morning it got used. Crazy.This system works well. Primary empties the pit quick and quietly. The valve works quiet as well (heard loud knocking with our old one). Install was easy. So far so good. I was hoping to buy a second for our other pit but the price has doubled?? Hopefully it drops back down.
