Q: Can you recommend an ACpowered sump pump with battery backup that would fit into a 14 deep x 12 diameter well? My current sump pump is a Ridgid Model SP500 12 hp, 60 hz, 120 volt, 3.8 amp.
Thanks.
Rick

by Rick G from Oregon on August 25, 2013

A: Thank you for your interest in Sump Pumps Direct. The Basement Watchdog 1/2 HP Combination Primary and Backup Sump Pump, model BW4000 will fit in a sump pit as small as 12” wide and 14” high (the size of a 5 gallon bucket). It measures 18“ inches from the bottom of the pump to the top of the "Y" connector where it will be attached to the discharge pipe.
The Basement Watchdog 1/3 HP Combination Primary and Backup Sump Pump System, model DFK-961 will fit in a sump pit as small as 10” wide and 14” high (the size of a 5 gallon bucket). It measures 17-3/4“ inches from the bottom of the pump to the top of the "Y" connector where it will be attached to the discharge pipe.
by Jim, Product Expert
Q: If the 120 v pump can't keep up it sounds as if the battery backup pump will kick in---but the units share a common pipe so how can you add water /flow to an already maxed out pipe?? Would this not just increase head pressure on the battery pump causing it to work even harder????
by Mark F from Wisconsin on April 10, 2013

A: Thank you for visiting Sump Pumps Direct. You bring up a very good and important point, Mark! Most primary (1/4HP - 1/2HP) and battery backup pumps discharge to a 1-1/2" discharge pipe and will be installed separately but due to the discharge system already in place, be piped or "Y'd" together. In MOST cases, the total pumping capacity by both pumps at the same time will be handled by that 1-1/2" discharge pipe and will not cause any extra stress or back-pressure on those pumps. That being said, for optimum performance of both pumps, they should be connected to separate discharge pipes. Again, that is not always possible. In cases of extreme high water tables and frequent possible flooding where high capacity pumps are required, you should definitely run a separate discharge pipe for each pump you have installed.
by Jim, Product Expert
Q: If the backup pump is activated due to heavy water flow (to help the main pump) and the AC power stays on, will the system keep charging the battery to allow the backup pump to keep running indefinitely?
by Scott Mueller from Connecticut on January 24, 2012

A: Yes, the controller will keep the battery charging and the pump running indefinitely if needed. This is true for the Basement Watchdog model BWE and the BWSP stand alone battery backup systems as well.
by Jim, Product Expert
Q: can you use a marine battery with this unit in stead of the 30hdc140s battery ?
also dose the unit have and automatic battery charge ?

by Mike G from Pennsylvania on January 08, 2012

A: You can use a standard marine deep cycle battery, however the Basement Watchdog Emergency Standby Battery has been designed to run the backup pump for a minimum of 6 hours continuously. However, most of the time the pump will turn on and off, and the battery will run the pump intermittently for days. In addition the unique materials in the battery enable it to last for 5-7 years in standby service.
To extend the run time of the pump, use the Basement Watchdog 7.5 Hour battery. It will run this pump continuously for 12 hours. Why will it run longer than 7.5 hours? Because the 7.5 hour battery is rated for other Basement Watchdog pumps that draw more power (amps). The emergency pump puts less drain on the battery, so the battery lasts longer.
NOTE: The battery will not run the primary pump.

The use of automotive batteries is NOT recommended. Automotive batteries are not designed for this application. They will only run the pump for a short time and will have a shorter life than a standby battery.
The battery fluid sensor and cap are designed to fit the Basement Watchdog batteries. Measuring the battery fluid is one of the most important features of the system; since about 80% of backup sump pump failures are the result of a battery that has dried out.

The control box that is included does also act as a battery charger.

Q: I have a DFK-961 and couldn't be happier with it. My question is what happens if the primary pump goes out? Can I replace it with the BW1033 from the primary pumps section?
by Steve Pierce from Wisconsin on January 04, 2012

A: Since the primary pump is independent of the backup system, pretty much any submersible pump pump will work. The BW1033 would be a direct replacement because that's the pump used in the system.
by Jim, Product Expert
Q: whats the difference in a sump pump that has a built in check value versus one that doesnt? I want a cast iron style, vertical float switch and wonder if buying this DUAL style sump pump is good or bad ??
by Kathy C Ranalli from Ohio on November 09, 2011

A: A built-in check valve is really a convenience in that you will not need to worry about it for the rest of your installation. All sump pumps require a check valve to keep water from flowing back into your basin once the pump shuts off. The dual style pump you speak of, I believe, is actually a Combo or Combination primary and battery backup pump already plumbed together for easier installation. They are a great idea for those that are looking to install a brand new system, i.e. primary pump and battery backup system or those that are looking to replace their old primary pump and add the battery backup system.
by Jim, Product Expert
Q: What size deep-cycle battery does the DFK-961?
by Anonymous on April 17, 2011

A: The recommended battery is the Basement Watchdog model 30HDC140S. It will give you about 12 hours of continuous run time.
by Jim, Product Expert
Q: does the battery box come with this unit?
by Jim on April 13, 2011

A: No, the battery box does need to be purchased seperately. It is available HERE for $12.99 plus shipping.
by Jim, Product Expert
Q: watchdog model dfk-961 what is the discharge rate for backup pump @ 10ft.
by Michael Wilson from Pennsylvania on March 03, 2011

A: The DFK-961 uses a BWE backup pump with 1000 GPH @10' lift.
by Jim, Product Expert
Q: is this a battery backup for power outage
by Bryan Emmers from Minnesota on February 11, 2011

A: Yes, the kit includes 1 Basement Watchdog 1/3 HP (BW1033) AC pump (2200 GPH @ 10 lift) and 1 Basement Watchdog Emergency battery backup system (BWE)(1000 GPH @ 10 feet). The battery is sold seperately.


by Jim, Product Expert
Q: Do I need a check valve with this unit?
by Elliot from New Jersey on January 27, 2011

A: These combination pump systems from Basement Watchdog have built-in check valves. An additional float switch is not needed.

Peace Of Mind
We live in the Pacific Northwest where the sump pump runs during the heavy rain season. That is also when we have frequent power failures from trees falling on the power lines. Sometimes the power goes out for days at a time, so this dual pump with battery back up is just what we needed. I bought the 1/2 hp model first, but it didn't fit in the small pit, the 1/3 hp version fit perfectly in a pit about the size of a 5 gallon bucket. The install took about an hour, easier than I expected. Thanks,

Basement Watchdog Dfk-961
Pump has performed as expected with no problems so far. I used a Duracell replacement battery which was less expensive than the branded battery. I did not realize, however, that the battery sensor needed to be placed in the 5th cell from the negative terminal. The online support was excellent and got me straightened out. The only issue I had was that the two required plugs would not fit in a duplex outlet as shown in the product literature. This is inconvenient.
Pros: I'd Buy It Again, Quiet, Features

Robert,
Thank you for purchasing our product. We definitely would like to assist you. If you are using a non-watchdog battery with the DFK961 it is recommended to place the fluid sensor under the positive post. We can also assist you with plugging both plugs into the same duplex outlet. Please call our service team at 800-991-0466 option 3 for technical assistance.

Seems Like A Great Product
Just finished my basement and wanted an added measure of protection in case we lost power. Pulled my one year old sump pump and replaced it with this unit. Took me maybe 15 minutes - tested unit and pumped very quietly. Have not hooked up battery yet as waiting for flooring to be done and cabinets installed adjacent to the pump to conceal the battery. Was impressed with the packaging and added features such as the battery monitor/duel pump controller/duel floats/etc. Also having both... more

About As Expected
I liked what I saw in the product description, and the pump arrived and matched expectations. So far, so good. I had originally intended to use a Marine battery, but after I read the instructions about the low electrolyte alarm I decided to get the Watchdog battery, and picked one up at a local Home Depot. I like that the package takes up little room in the sump, and all components seem solid. The float switches seem to be arranged to be relatively immune to the most common types of... more

After A Year & A Half It's No Good
I thought this was a great pump till it couldn't keep up the other day. I find on hard rains the main pump overheats and shuts off leaving the battery backup to do it's work for a while. This happened the other day and we had a heavy downpour and the Main pump overheated and the backup could just not keep up. I would've understood had their been a power outage, but there wasn't and all my carpet got ruined. Also the trickle charger has decided to stop working so I had to hook a car charger up... more

Brand Rep
John,
We are sorry that you are unhappy with this product. Please keep in mind that when the back up pump kicks in during a tough storm this doesn't necessarily mean that the primary is not working, but that enough water is coming in that it has reached the level of the backup float and has kicked in to help keep the water out. We feel that this is a smarter design than having your back up only kick in when power is not available. In your situation it sounds like you needed to go with the big Combo as it sounds like you may be getting more water coming in during tough rains than the rated GPH of the DFK961 Combination system. We do stand behind our product 100% and if there is ever any situation in which you would need our assistance we are always willing to do so. You can contact us at 800-991-0466 Ext.3 for technical support. For us it's not about getting a sale but keeping our customers happy.

Easy Directions
I had a Zoeller sump pump with no battery backup for many years and always checked that it was working when it rained. I checked it when it rained Sunday morning but the pump failed sometime Sunday night and I ended up with 18 inches of water in the basement by Monday morning, ruined everything.

The basement Watchdog system is great so far. Took 30 minutes to set up. Easy directions and everything I needed was in the box, even a rubber coupling and ties for the wires. I love the control... more

Beats Them All
I have gone though a couple different brands of pumps in my basement and this combo beats them all. I found it easy to install. The primary pump effortlessly and rather quietly empties almost my entire sump well in seconds and the back up pump works just as good.

I also purchased the battery and acid from Watchdog and found the back up battery to be an easy installation and hookup. I am overly sure that I have much more piece of mind and satisfaction than John has and hope this review... more

New Sump Pump System
After losing power during the first snowfall of the year, our basement was flooded. The existing pump was old with no backup pump to boot.

I ordered from Sump Pumps Direct and in only 2 days, a Basement Watchdog combo system was at my door. Installation was fast and easy and works like a charm!

The piece of mind this combo system provides is worth every penny!

Alloy Housing - Bad Idea
Loved everything about this pump when I bought it. The redundant float systems, controller and capacity of the back up pump are outstanding. BUT. The pump housing is made from some kind of alloy that must contain zinc. Our ground water contains a lot of dissolved metals and is a great electrolyte. What that means is the zinc in the housing is attracted to the dissolved ions in the water and eventually it simply dissolves. Mine had a fist sized hole in it before two years in service. Granted my... more

Ted,
We are sorry that were not happy with your pump. We would like to clarify that we do not use zinc in the construction of our products since we do know that this would cause them to deteriorate much quicker. It is not common that this would happen to the primary pump unless your water conditions are harsher than the common. In your case this pump may not be what you need but we do have a pump that we believe would be the right fit for you. Please click on the link below in order to see the S3033.
