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.

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

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.

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.

Small Diameter
Because the outlet is on top, not the side, this took up less space in small diameter hole. The float was easy to modify and extra contact provides better fail safe.

Hole In The Side After Only 1 Year Of Use
Do not buy this pump. Installed about 1 year... one afternoon my water alarm sounded on my smart phone. I was two hours away. When I got to the pump I noticed it was spraying water from the side of the pump onto my basement floor. Not good. Shut the system down to find a silver dollar sized hole in the side of the pump. When I read reviews from other sites I find the same issues. The casing of the pump is of poor quality and needs to be discontinued immediately.

Thomas,
Sorry to hear about the issues you're having with the pump. This is a water-cooled pump, high mineral content / high pH levels in the water being pumped can decrease the lifespan of the pump.

Basement Watchdog provides a 3-Year Warranty on this pump and can be reached directly @ (800) 991-0466.

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!

A few weeks back my area in upstate New York experienced significant flood damage and was declared a Nation Flood Disaster - I moved to the area last year and the prior owners had taken out the cellar sump pump...after heavy rains over 24 hours, our backyard quickly swelled to over 9 feet of watge when a nearby Creek reached flood stage...Fortunately for us we our got 3-4 inches in our basement, and the local fire department pumped us out twice....I went online and ordered this pump this same... more

Solid Pump, Timing On Vertical Float Switch Could Be Longer
I have had the BW1050 and it has been a workhorse. Our house is the lowest in the block and during moderate spring rains or heavy summer rains, our pump runs 40-60 times an hours.

The only problem I have with the BW1050 is that the Float Controller only allows the pump to run for 8-9 seconds. This results in the pump running more often due to the amount of water coming in.

Can I connect the pump to a traditional float switch so that the pump runs longer but less often?

A nice benefit... more

Good Pump But Has Shortcomings
Purchased the BW1050 pump to replace a similar pump that came as part of the Big Combo battery back-up system. The original BW1050 pump failed catastrophically after only 3 years.

The outer shell of the pump is cast aluminum and corrodes badly in the caustic sump water. Expect that this pump will likely only last a similar period.

Would be nice if the pump were made entirely of cast iron rather than aluminum and iron. As a result, the pump must be considered as a wear item and replaced... more

Peace Of Mind
I have two sump pump pits in a sub basement. The pit bottoms are 13' below grade. After the last few storms, April/May 2013 it was time to replace my ageing battery back ups. What I have done is use the same battery chargers with new batteries. I have added a 1500 watt power inverter to run these pumps in each pit. The current draw for these 1/2hp is only 4.2 amps. The inverter handles it with ease. These will pump 53GPM at a 10' lift. The adjustable 2 pole switch is a perfect match for these... more

I installed this pump with ease and it has worked great! The only complaint would be that the housing corroded after a little more than 1 year and the pump did not draw the water down to the limit depth. This was remedied very quickly with a phone call and a free replacement pump was on it's way.
I have the total watchdog system with battery backup and alarm.

We would like to also mention that if you do have a high mineral content in your water this may happen with any pump; but we do recommend that your pour a 1/4 cup of CLR, Lime away, or any variation of these products once a month in order to prevent this in the future.
