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.

I found the unit to be well made and compact in design. The pump will move alot of water and is virtually silent.I bought a battery locally and am impressed with the run time when the power is out. If you have extended power outages buy the largest battery that will fit the supplied battery case.The audible alarms are useful but not very loud.Overall, an impressive unit that is worth every penny.

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.

Our basement must have been built in the path of an underground stream. After a big rain, water will continue to come into the sump for several days after the end of the rain. Basement flooding is a certainty if the sump pump isn't working. So AC power, or no AC power the sump pump must continue to run!The AC-powered pump component is typical of good quality flooded pumps, powerful and quiet. But it is the DC-powered backup pump that sets this unit apart. We've had other DC-powered backup pumps, but they typically fell short. We have about a 7-foot lift between the top of the sump and the ground surface where the water is discharged. The other backup pumps would run, but strain to remove the water. Not so this pump. The backup pump design is very similar to the primary AC-powered pump and takes only about 30 seconds to empty an 18" round 30" deep sump against that 7-foot (minimum) head. In a recent test following a 4" rainfall event, the backup pump was needing to empty the sump about every 3 minutes during the peak drainage. It ran on battery power (admittedly off a 100-amp-hour AGM battery) all day and through the night without any visible drop in the battery voltage until there was no more water to be pumped.With one caveat, installation is easy, primarily because the plumbing interconnecting the two pump units is built-in. The caveat is that the base of the unit is massive, with the two pumps mounted side-by-side (instead of vertically as many of the lighter-duty units are). We have an 18" circular sump and it just barely fit - in part because while 18" was ample for the center of the unit, the corners just barely fit.We did make one alteration. We are charging our battery using a high quality, stand-alone charger. Why? The main limitation on battery life is likely to be how it is charged (or, if things don't go right, overcharged). The built-in charger may be OK, but given the cost of the battery, we thought investment in a computerized low-amperage charger was a reasonable one. The good news is that the pump control electronics built into the battery box work fine with the AC charger cable detached. The charger type makes no difference when the backup sump pump is actually running, because, by definition, the AC power will be off at that point anyway.Given its solid design and construction, and that it seems to do the needed pumping with little evidence of effort, I'm expecting this unit to keep us dry for many years .

After researching several battery backup sump pumps, I chose this one based on 2-year warranty, price, specifications and purchaser reviews. Installation was easy and it performs as expected. I have not had to rely on it yet, but I simulated a power outage and it worked exactly as it should. The overall cost, including a Group 27 AGM battery, pipe, fittings and a combination check and shut off valve was considerable (and that was installing it myself) but the peace of mind is worth it.

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.

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!
