Wayne ESP25 Upgraded 12-Volt Battery Backup System, Black

Bought the Wayne Guardian to replace a separate sump pump and backup pump. Much easier to install. I also like the external display and smartphone app which allows me to monitor the health of pumps and battery. Product arrived with a cracked redundant switch. I called customer support and they quickly sent out a replacement part. After installing and testing I had a couple of questions. When the tech was not able to answer one question she checked with the engineer who quickly resolved my issue. Can't ask for better support than that. This product is expensive compared to other combo units. But it is protecting my finished basement. A flood would be very expensive and painful to resolve. It is worth the extra money to me to know my pump and battery are functioning properly or need to be checked on.

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!

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 .

This sump pump works flawlessly. It kicks on quickly, moves water efficiently, and does the job without any loud rattling or vibration. I was impressed by how quiet it is—you can barely hear it running, which is a huge plus compared to my old pump. Installation was straightforward, and the build quality feels solid and durable. If you want a reliable pump that’s both powerful and quiet, this is an excellent choice!

this is the second house I equip with this back up pump, love it serves well when needed, plumber really liked it and was impress by its capacity compare to other brands
