Q: Is this pump capable of handling water softener and washing machine discharge?

if not, which brand/model can?

by Steve K from Wisconsin on June 06, 2013

A: Generally, sump pumps are not recommended for use in a water softener and/or laundry application. Just about all manufacturers will void the warranty if the pump is installed and fails in this application. You might check out our selection of LAUNDRY / DRAIN PUMP SYSTEMS as most of these self contained systems are designed for laundry and water softener applications.
by Jim, Product Expert
Q: What does min. sump basin size mean?
by John D from Massachusetts on February 02, 2013

A: The minimum sump basin size relates to the minimum size of your sump basin or pit, that a specific pump will safely operate in. Any pump needs a certain amount of space due to "on/off" levels, cooling factors and cycling that the pump is designed for. Most pumps will require a standard size basin of 18" wide by 24" deep but some will also operate in smaller basins. You want to pay very close attention to these requirements as they will insure a longer pump life.

Q: I would like to know how many watts a 1/3 or 1/2 hp sump pump has, because i was think of buying a portable generator in case the power goes off.
by Tom B. from New York on September 03, 2012

A: That really depends on the pump. Some are more efficient than others. For example, the 1/3HP Basement Watchdog model BW1033 has a running amp rating of 3.5 and a starting amp rating of 7. When you figure the watts by the formula of amps times volts equals watts ( A X V = W), you get 420 running watts and 840 starting watts. But when you look at the Zoeller 1/3HP model M53, that pump has a running amp rating of 9.6 and a starting amp rating of 29.6 or 1152 running watts and 3552 starting watts.
by Jim, Product Expert
Q: Jim, can i purchase only the battery?
by Mokke from Illinois on August 16, 2012

A: Could you please specify what pump you would like a battery to operate?
There currently is no battery capable of powering a 120 volt primary sump pump. The only possible options would be an auxiliary power system such as the ones shown at http://www.sumppumpsdirect.com/pumps/sumpro-auxiliary-power-systems.html which will operate up to a 1/2HP pump for up to 10-12 hours continuous or 24-36 hours non-continuous, a complete battery backup sump pump system ( http://www.sumppumpsdirect.com/pumps/battery-backup-sump-pumps.html ) or looking into the possibility of installing a standby generator. Our selection or generators can be found at http://www.electricgeneratorsdirect.com/power/standby-generators.html.
by Jim, Product Expert
Q: What kind of warranty do you have on your pumps?
by John from Pennsylvania on July 03, 2012

A: Pump warranties vary from 1 year to 5 years depending on the pump and the manufacturer. That being said, all pumps should last a good 5-7 years or more providing they are installed properly.
by Jim, Product Expert
Q: Can i order by phone
by Christopher from Virginia on April 11, 2012

A: You are more than welcome to call your order in to us at 888-455-4682. Our phones are open from 7AM - 7PM CDT Monday through Thursday and 9AM - 5PM Friday.

Q: Do you know if the watch dog 1050 has a start capacitor or a running capacitor?
by Scott from Indiana on January 08, 2012

A: The Basement Watchdog BW Series pumps are designed with a PSC (Permanent Split Capacitor) or run capacitor.
by Jim, Product Expert
Q: What is the running watts and the surge watts of teh BW1050?
by Bern Eckert from Illinois on September 28, 2011

A: 504 running watts and 1008 surge watts.
by Jim, Product Expert
Q: I have Beckett 1/2 hp submersible sump pump (80 gpm) Is a Honda EU2000 inverter/generator (120v, 13.3a) capable of operating this pump in the event of a power outage ?

Thank you

by Dick Denhup from Connecticut on August 28, 2011

A: If the 13.3 amp rating is the starting amps listed for that pump, then yes, it would power that pump. If, however it the running amps, most likely, you will need a larger generator.
by Jim, Product Expert
Q: I have the exact pump in my basement and it is getting stuck on the on position. It seems that the float was getting stuck, so I cleaned the gunk around it as best as I can and sprayed some silicon on it.

Any other suggestions? can the float cage be changed on these units or do I have to buy a whole new pump?

Thank you

by Ayad Bakir from Illinois on June 08, 2011

A: You have done about all you can, but the pump and basin should be inspected at least once every 1-3 months. If the pump runs fine without the switch, the switch needs replacing. You can find the same switch HERE.
by Jim, Product Expert
Q: Would this pump be suitable for a 12' x 12' basement?
by Cody Dix from Ohio on January 10, 2011

A: The interior dimensions of a basement aren't a major factor in sizing a sump pump correctly.

Monitoring your current pump during normal operation and during a storm can give you a better idea of what size pump you would need.

Who doesnít like to save money? Youíll end up saving money wit this energy efficient pump. The BW1050 only uses only 4.2 amps (compare to 10+ amps on other pumps) and earns our "Good" recommendation.

Combine that with dual float switches wrapped in a protective cage, it provides added redundancy and wonít get hung up like other switches often do.

Last, but not least this is an industrial strength pump that is rated for continuous duty, so you know itís built to last.

Works Great!
The pump is rock solid, hooked up very easily, and pumps like mad! The float was a no-brained to hook up and adjust. The best part of the system is the dealer, Sump Pumps Direct. I'll be back when it's time to replace them!
Pros: I'd Buy It Again, Price, Exceeded Expectations, High Quality

Does The Job!
Previous sump pump was approximately 3-4 years old, when it went out, we quickly ordered a replacement. It arrived within 3 days and was very simple to install replacement. Much quieter that previous model and certainly seems to DO THE JOB!

Replaced My Old Pump Painlessly
I am pleased overall with my basement watchdog system. I am, however concerned that the original pump malfunctioned after less than 4 years use. I was able to retain the 12 volt backup pump and electronics. This appears to be a well designed system. I would have expected it to last more than 4 years though.

Great Product At The Right Price
I went online for about 30 minutes, checked reviews and this one had the best reviews for the money. It took me 3 minutes to order and it shipped to my door in 3 days for $129.00 +shipping. Super simple install - 15 minutes to pull old sump and put this in place, plugged in and operational! Easy order, easy install, great price - I Very Highly recommend this sump for the average home.

Good Sump Pupm & Good Price
I like this pump except the shutoff delay is only 20 seconds as opposed to 30 seconds on the old one. Shorter delay means the pump doesn't draw down as much as the old one and will cycle a little faster when the water level is up.

Works As Advertised
I have installed the pump and tested it. It works exactly as advertised. My under house area is rock, dirt and sand. The hardest part of installing the pump was digging a pit to put it in. After installing it I tested it and it turned on and off as it was supposed to do. We have not had a heavy rain, 2 or more inches, since I installed the pump. So it is untested in heavy rain condition, but based on the test I ran I believe it will do the job.

Works Great
I bought this to replace our 16 year old sump pump which had been acting up. This pump is louder than the old one, however, it stays on less time per cycle and shoots the sump water about 5 feet away from the discharge pipe. I'm also impressed with the float switch design. So far, I'm very impressed.
Pros: Exceeded Expectations, Fast, High Quality, Large Diameter Discharge Pipe Really Moves The Water
Cons: Noisier Than Old One
