Can this battery backup system be used in a basement apartment if we use an AGM battery? We also have a kerosene monitor that has an open flame igniter that is within 5 feet of the sump pump.
Asked by: homeowner
Yes you can use it with an AGM battery, the battery water sensor will have to be attached to the positive terminal to bypass the monitoring circuit. However it is not a cost effective solution. AGM batteries cost 4 to 5 times more than lead acid batteries. Interesting to note, the basement watchdog systems are designed to be used with a Lead acid battery. The big dog system uses an advanced controller to maintain the battery, so most times it will not be in continuous charging, which means least amount of emission form the battery. How much hydrogen will the battery emit? One lead acid battery probably not enough to be of any concern. With an open flame nearby? Hydrogen like helium rises rapidly, so if the flame is closer to the floor, five feet away, it would probably not be an issue. I would add a fan in the room to ventilate the area where the charging system and battery are located. Alternatively, the wires from the controller to the battery which consist of positive, negative and battery water sensor can be extended to place the battery in another location further away from the open flame. Which is still a more economical solution than purchasing an AGM battery.

What’s the difference between this and the 1/2 hp big combination

Asked by: ShDelma
Its my understanding that the Big Combo essentially uses the “Special”-grade DC only pump/controller whereas the BigDog is AC/DC pump/control unit with advanced electronics/monitoring capabilities including periodic self-test, etc.

A new BigDog is; an older BigDog unit may not be. Check Glentronics website for mfg date/serial number compatibility

1/3 HP Big Dog Computer-Controlled AC/DC Battery Backup Sump Pump System is rated 4.2 out of 5 by 50.
Rated 5 out of 5 by from A Great Buy but..... EVERYONE READING THIS.... make sure you UNDERSTAND THAT THIS DOES NOT COME WITH A BATTERY OR ACID. I wish Glentronics would simply package the battery with this. Its sort of dumb.... you need a battery since the system will not work w/o it. Yet they sell it seperate. I ended up using a marine battery from my boat until I got time again to go to home depot to pickup the Glentronics / Watchdog battery. (Another $100). This is a great system. I have put it in unfortunately after the fact. Will the lesser models work.... yeah I imagine they would but when I saw the water pouring in over the sump pump cover after the power went out, it was scary to see how much water was coming in. Within 2 - 5 minutes, our basement (approx 2000+/- sq ft) was covered in about 2" of water. Soooo that being the case, I opted for the most GPH pump. I was thinking about putting in a generator but decided on this for the interim. This unit also gives you more information feedback than the other 2 lesser models. It also tells you how much more battery life is left.

Rated 5 out of 5 by from Saved my basement many times This was the second system I have purchased and it has earned it's keep several times over. I live on 2 1/2 acres that are surrounded by wetlands. I have drain tile around the inside of my foudation so my sump pumps fill and drain about every 3 mins 24/7. So when the power goes out, which it has I can flood my basement 4" deep in 45mins. best thing I ever bought for the house besides the drain tile. Alarm goes off to tell me when the power goes off or there's a problem with the main pump. Only 1 problem. DON'T wait for the low water sensor to tell you when to fill with water. Do it once a year, trust me. I waited and we had a tornado that knocked out power for 4 days. Smoked the battery. Other than that, you can't go wrong. I own 2 systems. Well worth it.

Rated 5 out of 5 by from $600 or $6000 you decide. This is the best backup system you can buy. I paid about $600 for complete system and installation, and is the best money I ever spent. It has saved my basement time and time again from the unrelaible power company, and bad main pumps. My system is almost 5 years old, same battery with no issues; it even tells you when you need to add distilled water. This unit is completly relaible. When storms roll in and power goes out, my wife and I sit back and just watch the storm pass by without a worry. If you are unsure about buying a unit and you have a finished basement think about this. A estimate for restoration company to come out and reapir damge to your capreting, walls etc can cost $6,000 to $10,000! How do I know? Because several of my friends and familiy didn't take my advice on the WatchDog and paid thousands out of pocket. Additioanly most insurance companies cover very little, natl avg only $5,000 (unless you ask for more coverage and pay a higher premium) after you pay your deductible. My $600 INVESTMENT PROTECTION (WatchDog) has easily paid me back 10 times over. Go get it now before the next storm washes away your rainy day savings.

Rated 5 out of 5 by from I bought the Watch Dog battery back up system last summer after installing drain tile in my constantly wet basement. My sump pump now runs 24/7/365. We had so many power outages last summer that I flooded the basement several times. I purchased the Watch Dog system and have been dry for the first time since moving here 9 years ago. It has saved me from bailing water from the pump well to renting a generator numerous times. Last week the main pump failed and it was 3 days before someone could come and replace it. The Watch Dog took over, running on A/C electrical from the house and when the company came to replace the main pump he told me with the amount of water we have it's a good thing I bought that system. Awesome Product!!

Rated 5 out of 5 by from A must have for basements with sump pits This product has saved my basements on several occasions. The system has a powerful pump, charger, several monitoring features and easy to follow step by step instructions on how to install and troubleshoot the system. The company also has outstanding customer service. I used two 7.5 hour Watchdog batteries (in parallel) for each system which provides days pumping capacity. You would need a parallel jumper cable which I bought from the manufacturer. One piece of advice…although the system monitors the battery fluid levels, which works very well, I like to check mine when I turn the clocks back or just before going on vacation. Overall great product!!!

Rated 5 out of 5 by from BONUS--it's compatible with an AGM battery DItto other Excellent reviews. The only thing I'm adding is the fact that the electronics on the Big Dog model (as well as the inexpensive BWE ) are fully compatible with an Absorbed Glass Mat (AGM) battery according to Tech Support. Why is that important? Because, AGM batteries don't produce hydrogen gas when they charge--so pilot lights and other ignition sources in the basement pose no problems! They won't leak or spill even if they're broken, they survive most freezes, and warranties are twice as long as a lead -acid design. (I am NOT an advertiser--just a very happy camper)

Rated 4 out of 5 by from It Works and Has Good Displays I installed the pump myself (no experience). You just need to be willing to cut and glue PVC. It took 2 hours to install. The operation of the pump is very straight forward and easy to understand. The controlling unit has good displays. One month after installing, a big storm knocked out our power. The unit kicked in and took over for the 4 hours we were without power. Water was coming into the sump fast, but it had no problems keeping up. You may be happy with the cheaper versions, I don't really know all of the differences. I do know that I have peace of mind with this thing installed. I would have rated it as 'excellent' but at $560 including battery and acid, it seems like a good value (not an excellent value).
