Questions & Answers

My old pump would activate multiple times a day every day year round. Is this a good product for me?

Asked by: MegaSkilos
I replaced a 40 year pump with this one because I was afraid it would fail due to its age. I am really happy that I did. With all the rain we got this summer it really got a workout. It ran every 6 minutes for 2 days. It worked very well and saved me from having a flooded basement. I don't know if it will last for 40 years but it has worked very well so far.

This system doesn't work period. Don't buy this system. Mine failed 2 months later and Glentronics puts up a fight to warranty it.

Does this system come with battery
Asked by: aledens
Yes, however the pricing was separate for Big Combination Unit and the battery. Also you will have to buy acid for the battery.

Customer Reviews

1/2 HP Big Combination Unit with Special Backup Sump Pump System is rated 4.1 out of 5 by 154.
Rated 2 out of 5 by from Disappointed Big Time The sump pump system was ordered approximately 30 days ago. I wanted it on hand so I would know how to size it to the sump basin. Since ordering it, I've been busy digging the sump, installing the basin, installing the discharge line, running a separate GFIC, etc. I set out to install the pump in the basin today to find that the backup pump float switch is broken loose from the cable that leads to the control unit. I also noticed that the top of the bracket that mounts the backup pump to the main pump was broken. I found the backup float and the top of the bracket laying in the bottom of the box. I suppose I can glue the top back on the bracket but I shouldn't have to do that. Either the factory quality inspector or the carrier has caused me some big time problems, I'm "dead in the water" on this project now and I'm not happy. I sure hope we don't have another heavy rain before this gets sorted out. Last, I can't comment on recommending this system until I get resolution.

The Basement Watchdog is an excellent product I've used for over 10 years now. I highly recommend the product- but can't recommend the company because they won't honor their 1 year warranty on their battery. I bought their large wet cell battery which packed up after only 9 months (controller unit posted a battery error). I had the battery tested (which would not hold a charge) and called customer service-- and they recommended I have the controller tested. Since I couldn't go without the unit in my basement, I bought a new battery and hooked that up. The new battery worked fine with the controller - so no issue there. But even with that information, (and the original receipt for the first battery- which I had kept) customer service still would not honor their warranty. Too bad- because otherwise, it is a great system.

Rated 5 out of 5 by from Well thought out and packaged product To start, my pump went out in the middle of the night so I was up all night bailing water out of my sump hole. had to redirect the back up pump to pump using a garden hose as it could no longer push the water up 10ft through a 1-1/2" pipe. So thank goodness Home Depot opens at 6:00AM. I was on their doorstep first thing. Purchased this pump after spending 3hrs researching the web, for the package of the main pump, back up pump, directional valves and controller. All in a small package and no loose float (mine would get pinched against the wall of the hole cause the pump would walk due to vibration from running). Very simple installation, anyone could do this. Bottom line i was still into work by 8:30AM. Also very quite, i know no longer hear the pump running from the bedroom. Awesome product and great value when you add up everything you get, try and buy it all seperate at a lower price and same quality.

A dual pump, each with dual floats and a battery backup power and a monitor that can connect to your security system or your phone. Problems: Battery not included Wireless capability module sold separately Definitely does NOT move the 3k+ gallons per hour as advertised. The cheap pump I had before move water faster. Because the water does not get pumped as fast, the backup pump keeps getting activated. The built in monitor keeps beeping because of the backup pump gets activated. Bought the maintenance free battery, grounded the battery fluid cable as per instructions, and the thing keeps giving trouble signals and beeps. I left the old pump in the same pit, which is the one avoiding the water to overflow. Again, great concept but it’s not performing that way.

Since this sump pump is brand new I am really commenting on the last Big Dob Combo Unit. I had several issues with it when I bought it around 5 years ago. Three times it went back to the repair facility. The company eventually replaced everything but with used reconditioned parts. Flash forward around 4 years later and I hear the big dog main pump running and running. I pull it out of the sump and find several dime size holes in the case. THE CASE RUSTED THROUGH. I called the factory repair guys and said I have two other sump pumps, 5.5 and 8.5 years old respectively from other companies and they are fine. All the Big Dog reps said was I need to follow maintenance procedures on pumps. They need to have CLR run through them periodically. You must wash the outside of the cases, etc... I think it sucks but did not have time to cut pvc and install a different brand during spring rains. PS the rep was really rude too. I would not buy this brand.

Rated 1 out of 5 by from Poor Quality - Aluminum Housing Rotted Away after 1 year forcing an emergency replacement I purchased the complete Watchdog system from Home Depot including the expensive backup battery. The total cost was about $550. After about 1 1/2 years I noticed the pump was cycling 2 to 3 times in a row. The next night it started making loud noises. I checked the sump and watched it pump. The entire well swirled like a torrent and splashed water everywhere. So I pulled out the pump and the walls of the aluminum housing had eroded. The pump housing had 3 holes the size of nickels to quarters. Water jets out of the holes causing the agitation and the pump starts groaning. So, at 9 pm that night I had to run to Home Depot and buy another pump to keep my basement from flooding. I paid $550 and didn't get 2 years from the Watchdog pump. My previous pump lasted over 12 years. Needless to say, I'm very disappointed and can't recommend this system to anyone. I uploaded a picture of the housing.

Rated 1 out of 5 by from BEWARE OF BASEMENT WATCHDOG PRODUCTS! I purchased the Big Combo unit with backup sump and batter... BEWARE OF BASEMENT WATCHDOG PRODUCTS! I purchased the Big Combo unit with backup sump and battery in July 2014. In Jan 2018, the main pump failed. On Jan 29, 2018, I called the Glentronics customer service number at 800-991-0466 to explain the situation and my troubleshooting efforts. The customer service rep (Eric) was short with me. He simply gave me a replacement pump number to search online and buy (saying it would be cheaper for me to order from Home Depot/ Lowe’s than directly from them). I told Eric this was unacceptable. Though the product warranty had recently expired I paid about $500 in total for their combo product. I have not had these issues with other sump pumps in other houses. He apologized and said it was the best they could do since the warranty expired. BASEMENT WATCHDOG/ GLENTRONICS: IF YOU SELL A SUMP PUMP PACKAGE FOR ~$500 AND THE MAIN PUMP FAILS AFTER 3.5 YEARS, IT IS AN INFERIOR PRODUCT. IF THE BEST YOUR CUSTOMER SERVICE CAN OFFER IS FOR THE CUSTOMER TO PAY IN FULL TO REPACE THE PUMP, IT IS INFERIOR SERVICE.

Rated 1 out of 5 by from Stop listening to these installation reviews. A proper review for a product that costs over $500 ... Stop listening to these installation reviews. A proper review for a product that costs over $500 with the battery does not come after the system is installed. Look at the pictures of corroded systems. That is what you will find. Within 1 year my system had a hole in the side. The company sent me a replacement main pump but I was never able to get the screw in coupler off even with a strap wrench. I just let the system run on the backup pump for two years. Last night that failed. I had to rig the replacement main pump up, holding it in place with water splashing all over for four hours off and on. My wife is headed to Home Depot now to get another one when the store opens at 6AM. I'm sure the second system will fail within a year or two but I'm too tired to rebuild the piping today. I can't leave the house or my basement will flood and I can't go to sleep either. If you want to feel like your body is shutting down from exhaustion guy the Basement Watchdog. I can't tell you what to buy that work better - I just know what this system will do for you.
