Answer: 
The combination unit already has a weep hole pre-drilled so it is not part of the installation instructions. A backup unit only requires the installer to drill a weep hole.

Answer: 
We do not recommend that certain components of this system be exposed to the Elements. The Controller Shouldn't be exposed to rain or extreme weather. As for the pump, we recommend they pump clear ground water since too much debris can cover the stainer therefore preventing the water to be pumped effectively.

softener discharge

My water softener discharges into my sump well, so that during dry times of the year when no other water is entering the well the sump pump handles salty water that comes from the conditioner when it recharges the unit. Will sometimes salty water corrode or otherwise harm the pump?

Customer Reviews

Rated 4.3 out of 5 by 67 reviewers.
Rated 1.0 out of 5.0 by Rusty junk 3 years and the housing on the pump has water blowing out of 3 rust holes the size of a nickel July 13, 2016
Rated 1.0 out of 5.0 by Do Not Buy Basement Watchdog This pump failed after only 4 years of use. I installed this pump 4 years ago and as the pictures illustrate it completely failed. The company (Glentronics, Inc) could not provide me with a reason why the pump deteriorated in such a short time. It's obvious they use substandard material and/or poor workmanship. December 1, 2015
Rated 5.0 out of 5.0 by Great sump pump! Our old sump pump (20+ years) failed when we got a lot of rain from the remnants of Hurricane Isaac, partially flooding our basement. I did a lot of research trying to find a quality combination primary and battery backup sump pump at a decent price, and I definitely found it! Home Depot had a very competitive price and got it to me very quickly. This was my first sump pump install, so it took me some time, but it was very easy. The only drawback was that I had to buy the battery and acid separately and pour the acid into the battery myself - a little nerve-wracking, but no problems. I thoroughly tested the system, and both the primary and battery backup pumps work perfectly. December 3, 2012
Rated 1.0 out of 5.0 by 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. April 8, 2015
Rated 5.0 out of 5.0 by Had for over a Year and still going strong I purchase my home in 2014, and it had a dry basement with a sump pump in it. I live near a creek so the water well fills up all the time, even during the summer. Less than a year later the sump pump, started to act up, and the switch was sticking. I did research and purchased this pump, because of the battery backup system, the extra pump, and switches. Installation was not hard, cut the old pipe, slide in the new pump, used a rubber coupling and there you go it was installed. Had the pump installed in 10 minutes, plugged in and pumping. Then I installed the battery and the charger. Took a little to fill the battery wells and let the fluid settle, and top off, but again not a big deal. I have had this system installed for a year now and had a 6 hour power outage and the system worked like a champ. Alarm went off, battery backup worked, basement stayed dry. Power came back on, alarm light stayed on to tell me that the primary pump was off for a while, battery charged backed up, I cleared the code and everything is running great. I see the negative reviews, and I read all of them before buying this pump. That’s why I waited for a year of use to write this review. This is a good system, and it works. Yes a little pricey when you buy the battery and all, but better than not having piece of mind. All in I think I had 450.00 in the project, but again better than a wet basement, and ruined pool table. Before you install watch YouTube videos on how to install a sump pump, it will make you feel better about replacing one if you never have. This is a good system for the money I spent and would do it again in a heartbeat. It is worth the peace of mind. April 12, 2016
Rated 5.0 out of 5.0 by Ease Your Mind and Buy This Dual Unit My urban home is located in an area that may have groundwater flowing twelve months a year. The operative word is "may" as my sump basket was bone dry for 30 of the 33 years since I built the home. This past year (2016) I've heard my sump pump occasionally pump throughout the year. As spring approached with natural increased water flow, I became concerned about what would happen during a power outage, if I weren't home to immediately start my generator. My existing sump pump seemed to work without any problems, so I explored installing just a battery powered backup. After taking all the measurements, it became very clear that my sump basket might be too crowded and create a problem. After reading the brochure, I decided the Basement Watchdog 1/2 HP Big Combination Unit with Special Backup Sump Pump System was, by far, the best possible option. It's virtually pre-assembled and extremely compact. I also purchased the largest companion battery. I recommend going to the Basement Watchdog website to view the installation video before you begin installing the unit. At You Tube https://www.youtube.com/watch?v=0Nlu4DD77Zo In the video, the spokesman will tell you this is a 5 minute installation. What he neglects to add is that the procedure for filling the wet cell battery takes about half an hour. You fill it; let the acid settle for 20 minutes, then top off the cells. You must pay close attention to how the AC plugs are plugged in. Plug them in wrong and you'll likely disable the backup and won't be charging the battery. After installation, immediately test the AC pump. The float is well concealed and you'll need a narrow dowel or pencil to lift it. The battery float, on the other hand, is very visible and is easily mistaken for the AC float. The unit is unimaginably quiet. When my old 1/2 hp pump switched on, I always heard it. This one is so quiet, you'll rarely hear it operate. All that said, all batteries can be run down if there's no means to keep them charged. If there's a chance of an extended power outage, anyone in my situation should have a generator on hand with sufficient fuel to operate it. March 29, 2016
Rated 5.0 out of 5.0 by Excellent product! I was a little worried that it would be complicated to install but really it was easy just like in the video. It took me 2 hours to do it only because I kept repeating the video to make sure I was doing it right. An expert would probably do it in 30 mins. Having everything is the key. Here is a list of what you need. The watch dog sump pump system Watch dog battery which was not included in the sump pump The battery acid which was not included I with the battery purchase 1 1/2 in rubber pipe connector In my case I needed to cut the PVC pipe which was not a big deal and connecting it to the main pipeline with the rubber connector. I just used the old PVC pipe from the old sump pump. Remember to date your sump pump so that you would know to change in the future. I would say between 8-10 years should be a good benchmark. Good luck! April 27, 2013
Rated 5.0 out of 5.0 by 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. February 1, 2013
