The Basement Watchdog Emergency Battery Backup Sump Pump pumps 2,000 GPH at 0 ft. of lift or 1,000 GPH at 10 ft. of lift. This convenient pump fits next to the main AC pump and automatically begins pumping during power outages, when the main pump fails or when water flow exceeds the capacity of the main pump. Its unique monitoring system sounds an alarm when maintenance is needed or a problem arises. A display panel indicator light will identify the cause of the alarm and the proper corrective action.

I bought the equivalent of this pump at the Home Depot in 2003. I live in an area that has a lot of groundwater...my 1/2 hp primary pump runs every 10 mins during peak flow, approx 40 gals per min @ 8' head (lift). I always thought if the main pump went out, this thing would be dead in 1/2 a day at best. In 2006, we had a horrendous ice storm here, some areas without power for over 10 days. This pump ran faithfully every 5-10 mins (using a 2 year old 925 cca boat deep cycle battery), and was still running when the power came back on after almost 4 days! It truly surprised me for a product in the entry level range. I attribute this partially to: 1. a careful installation with special routing to keep the discharge lift under 5' (I cheated and went directly through the foundation wall into a storm sewer, rather than up-and-over the foundation), and 2. A good battery. But be sensible folks- know what your primary main pump capacity is, the lift, and how much it is pumping (hint: check the charts at your primary pump manufacturer web site, then charts at the basement watchdog site). That will tell you if this pump can handle it. If your primary pump runs nonstop during storms, 1. its probably too small, and 2. you better plan on multiple backups, or something else with high capacity. And by the way, although the battery is not included, most Home Depots DO carry 2 models of the dry battery and also the acid to be added, the benefit here is a truly "new" battery, which can be serviced (not sealed), and accepts the voltage probe (although the unit will still function with the probe). The higher the amps of the battery, the longer it will pump, and the more you will pay. If the HD doesn't have it, you could also consider a serviceable deep cycle marine battery. After almost 10 years of service, 4 batteries, and multiple power failures without mishap, I have decided to get a new one...you guessed it...this one again. One welcome improvement is the fact that the alarm can now be switched off during an event, and the float switch is now redundant (2 floats). Advice? 1. Keep the discharge pipe completely separate (after all this IS an emergency system) from other plumbing and as LOW as possible. 2. test the system regularly and expect to change out the battery every 2-3 years (don't forget you can recharge the battery from your car in a pinch or even use the car's battery in a real emergency). 3. try to mount the pump with support UNDER the pump. I had a neighbor with this exact model and their basement DID flood...our investigation found that the installing plumber hung the pump by the discharge pipe which cracked the base housing, so the pump ran but did nothing. 4. Be sensible and make sure this pump has the capacity you need...you can even call their tech support- I have found them to be very helpful- the system will only be as good as the installation. I hope you have the same good luck I have had with this pump.
Installed this myself about 8 years ago after we moved in and the former owner told us horror stories about coming home to a flooded finished basement. It does an adequate job of draining the sump pit properly when the power's out (happens once or twice a year, on average). I haven't been careful about maintaining the battery, and it's lasted until just a few days ago, so no complaints there. Only time it gave me pause was when we had an extended outage that lasted several days; it was Spring, so we probably had more water than usual, and the battery gave out after about 24 - 36 hours of intermittent usage, after which I ended up hooking up a generator to the house anyway. Overall, I'm glad I have this thing, but it doesn't give me complete peace of mind when we're away for extended periods and in that case I have the house-sitter double-check it. However, I have to say that this pump has never let me down so far. I do have one massive complaint, though: there is NO WAY TO SHUT OFF THE ALARM, and if your power goes out, the alarm will sound whenever the pump cycles. (There's a reset button that shuts it up, but only until the next pump cycle while on battery). In other words, if you have an extended outage, the alarm will be screaming continuously and can't be stopped. I fixed this by adding my own switch to cut out the speaker (which almost certainly voided the warranty). Wish they had built this option into the alarm somehow.
1) I have a 10' lift and this puppy struggles moving the water. 2) The battery lasts less than a year (and I maintained it according to the instructions) - the charger basically overcharges the battery to death. 3) It doesn't recognize a dead battery until it attempts to use the battery, and then it's too late.
Bottom line, I would not recommend wasting your money on this unit. I honestly don't know if there's a completely reliable system out there for under $600, but buying this system just gives you a false sense of security and you'll find yourself replacing it anyway.
Pros: Easy to Install
Cons: Too Slow, terrible charger, cheap electronics
I just installed this backup sump pump. It was a pretty easy install. It took me about 3 hours, but that included draining and cleaning/scrubbing the sump pit. I also installed all new drain lines and check valves.
I tested the unit and it worked as expected. I only have about 6 ft of lift from the bottom of the pit, so it handled the water fine. However, I am not sure how it would hold up if it were to run continuously. When the power goes out, I have a backup generator that will provide power to the main sump, but it is nice to have the battery backup to give me more time to get the generator fired up (or if I am not home when the power is out). It is also nice to know that it will kick in as a secondary sump if the main pump is not functioning correctly. Overall, worth the price for the peace of mind.
Speaking of the price, when I went to the store to buy the unit, I was not aware "batteries sold separately." So, although the backup kit is only $140, add another $100 for the battery, and another $25 for the battery acid. That trip to Home Depot cost me $320 for the above, plus the new check values, 1-1/2" pipe, Y-connector, 45 degree connector, PVC primer & glue, and a new surge protector to help protect the investment.
I bought a home with this system professionally installed 15 months ago. I am ripping this out and installing something new. It did pump as a back up, but audible alarm will not silence even when turned off. If battery drains a little due to pumping, alarm will sound until battery is completely charged. Imagine a smoke alarm that will not shut off. You have to dissconect from battery (with wrench) and power brick from wall. After my unit screamed all night and battery would not take full charge....it's got to go (Yes water level in battery was maintained) Bottom line..does work, but will drive you insane.
I found that 10feet of lift is the extreme limit of the standpipe is filled with water already due to the return to the backflow valve. Remember that the lift is measured at the bottom of the sump tub so most homes will need about 13 feet. As a consequence the yellow supplement is useless and when needed will just run until it drains the battery out. This is not recommended unless the pump is in a crawl space.

Review 9 for Emergency Battery Backup Sump Pump
Economical backup system but watch OUT for Watchdog glitches.
PostedFebruary 17, 2014
Ease of installation
No, I do not recommend this product.
Worked well for first 4 years considering that it never was called into service since our power never failed during a flood. I had a problem one day, the battery alarm went off. Okay, so checked all the internet sites, and checked the FAQs for Watchdog. Unfortunately, none of these gave me the correct answer. I first assumed battery was dead, so I replaced it which is a lot of work lugging 60-lb batteries, and cost $150+. But the alarm started again, so my friend brought his multimeter and we tested it. Seemed that the charger was dead, so brought that into Glentronics headq which LUCKILY was only about 15 min drive away. The guy there replaced the charger, and billed me for it but did NOT even mention any other probable cause of failure. So... when that charger again went dead soon after, I came back and the support guy there now says right away likely it's a failure of the main control unit itself. This is not something even mentioned in the website FAQs, It SHOULD be mentioned by them (hint hint guys, put it out there). So, I did have to tear out the control unit (snipping wires) take it in and have it fixed which they did charge me for (hmm, I could see them doing it gratis since it was a part failure). So I have mixed reactions. The thing does work but if it does fail you may have to spend some time/effort/money to fix. I suppose you get what you pay for so my advice, check your options when considering your backup system! Perhaps a few hundred dollars more for a pro system may save you some grief in the long run.
This all-in-one kit is very easy to install and gives me (and my wife) the piece of mind we need. Our finished basement is our central area for lounging and TV viewing and is also the home of my in-home office. A basement flood would be the end of most of our electronic gadgets (PC's, TV's, DVD/BluRay, etc) as well as our memories (digital pics and videos stored on our PCs).
Our standard sump pump is a trooper and never makes us doubt it's ability to remove water from the basement, when we the power is on. We've had a couple bad storms this year with extended power outages and we were very anxious about basement flooding the entire time.
This is the 2nd one of these kits I have installed. I hooked up one at the in-laws house and was so pleased by theirs that I added the same setup in my own home.
The pump, while compact, will move water and move it fast. It's a nice unit and comes with everything you need EXCEPT: Battery and check-valve(s), and of course PVC pipe and accessories to hook it up.
I would buy this product again, and if I ever have to install a battery backup sump pump, this will be my first choice. I would recommend this to my friends and family!
I bought this unit about a month ago. We get water only if there is a really heavy rain. That really heavy rain just came and the sump pump is running perfectly. Installation from scratch was easy and can be done in a day. Since it's is only needed in heavy storms -- when we are most likely to loose power -- I chose to use this unit as my only sump pump. There was no pump in the house and I didn't want to dig a huge hole so I decided to use a Home Depot bucket. I drew a circle on the floor about 2 inches outside the bucket diameter. Then I drilled a 5/16 hole in the floor every inch around the entire circle. I rented an electric chipping hammer (a small and manageable jack hammer) to remove the concrete from the hole. Then I dug the hole big enough to hold the bucket with the rim about an inch below the floor level. I set the bucket in the hole and put three one inch plastic pipes vertically on three sides of the bucket. The pipes extend to a couple of inches below the floor and several inches above the floor. Then I poured and packed gravel around the bucket to the bottom of the floor level. I used the gravel removed from the hole. Then I filled the rest of the hole with cement (sand mix) and tapered the top from the bucket to the floor, making the bucket into a big funnel. Once the cement is totally set, the three pipes can be trimmed to floor level. I left the tops open so that I could clean them out if they ever clogged. Using the hammer drill, I drilled a 3/4 inch hole through the bucket into each of the pipes just about the level of the bottom of the floor. These holes let the water into the bucket when it gets to the bottom of the floor. I used a 220 Amp hour deep cycle battery that I found for $92. I've been using these batteries in my motor home and they last five years under heavy use with a proper three stage charger. I have no idea how long it will last with the cheap charger that comes with this unit. The pump takes about 10 seconds to empty a foot of water from the bucket. The drain is straight up 9 feet from the bottom of the bucket, through a back flow valve just above floor level, around a 90 elbow through 2 more feet of level pipe, around another 90, down 3 feet to ground level, through another 90 and out a 2 foot line to a splash block. The pump is currently running for about 30 seconds every 5 minutes. The pump runs for about 20 seconds after the water is gone. The instructions have other steps that must be followed. Strangely, they are only available on line. None come with the unit.
Pros: Easy to Install, Good Instructions, No Leaks
Id recommend this for anyone who doesnt see a lot of activity in your pit, mainly for peace of mind when you get that rare storm or snow melt. Ive had days when a zoeller pump handling 3000 gph was nonstop busy. Clearly this watchdog pump wouldnt have a chance if i lost power in a storm like that. Decent if you just need some sort of backup, look elsewhere if your sump pit means business.
I installed this system with the large watchdog battery as a back up to my Wayne 1/3 HP A/C pump in February 2013. It works well when tested. One problem is the battery charger. My battery specific gravity readings have been 1.285 on 3/29/13 ; 1.275 on 4/11/13 and 1.250 on 5/10/13 . As you can see, the battery is slowly discharging while sitting in ready mode. Others have stated that the charger is not up to the job. I have to agree. I recommend a supplemental charger or replace the charger with a 750 ma charger or larger. I am currently using a 10 amp 6/12 volt charger my grandfather left me to charge the battery occasionally when needed until I can get a better trickle charger. Good Luck.
I recently purchased the Watchdog Emergency Pump for a backup system to an existing pump in a home I just purchased. The directions were very good and made the setup a breeze. My only problem with it is that it is not powerful enough for my needs and upgrading to The Big Dog is just a little too steep. Although I like the fact that the Watchdog systems check the Batttery fluid level, I will probably be opting for the Wayne 3300 gph wich comes in a lot less $$. Overall though if you don't have a severe sump intake as I do this pump is a great value.
Installation was easy. Make sure you follow the instructions as outlined. It took me a little over 30 mins to complete installation. I chose to use one of my Marine Deep Cycle batteries to defer cost. As the instructions state, "attach the probe to the positive terminal to turn the alarm off". BTW, the battery works just fine. I hope I don't have to use it but I'm glad it's there.
Pump was very easy to install. When tested, works great. My piping from pump to discharge out of house is about 9-10ft - pump has no problems pushing out. Size of the Watch Dog easily allows for two pumps to sit in bottom of tank.
Pros: Reliable, Easy to Install, Good Instructions, No Leaks
I have had this pump for about 13 years and it has worked well, the other day I tested it & did not work, took it apart and the pump motor was filled w/water, I guess the seal failed, but after that time that is to be expected. I dried it out and is now working but probably is due to be replaced. I am going to buy the same thing to replace it. My main pump is a 1/2 hp. If power does fail it is likely to be during a big storm and if you have a high water table and bad water problem like me, this pump would be greatly taxed and would probably have to run continuously. Therefore you'd better pray that the power comes back w/in 6 hrs or have a generator.

Review 18 for Emergency Battery Backup Sump Pump
Failed to start in emergency situation
PostedMay 29, 2011
No, I do not recommend this product.
This was installed about 2 years ago. I would check it every 6 months and everything seamed fine. The first time it was actually needed (last week) it did not start. The light showed that the pump was running, charge and battery were fine. Afterwards I tried the test button. Showed the pump running but in fact it wasn't. Pump fail.
Not a cheap item to replace and I have lost faith in a product that is designed for an emergency and doesn't work when needed.
I see the higher models cycle themselves once a month to test. Does this actually test that water is moving or just that it has told the pump to work? If it is the latter, then it is a pointless test as it would have the same result as my problem.

Review 19 for Emergency Battery Backup Sump Pump
PostedMarch 13, 2010
No, I do not recommend this product.
This product has never worked. First the connections corroded away within weeks of having it installed. We sent back the corroded piece and the company did promply return, however, upon installing once again the unit never stops beeping and we cannot figure out why. Save your money and go with another brand, this one is too frustrating.
there is problem with keeping the battery charged i installed a trickel charger besides the built in charger an it saved my house many times.....just bought 2 more today to install at a job ...if you have a wet basement and dont install one of these you deserve to get wet....i do this for a living...after it saved me several times anyone that complaines about this has something wrong with them
Pros: Reliable, Easy to Install, Good Instructions
