Is this pump capable of handling water softener and washing machine discharge? if not, which brand/model can?
Steve K 
from Wisconsin 
June 06, 2013
Answer
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.

What does min. sump basin size mean?
John D 
from Massachusetts 
February 02, 2013
Answer
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.

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.
Tom B. 
from New York 
September 03, 2012
Answer
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.

Jim, can i purchase only the battery?
Mokke 
from Illinois 
August 16, 2012
Answer
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.

What kind of warranty do you have on your pumps?
John 
from Pennsylvania 
July 03, 2012
Answer
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.

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
Dick Denhup 
from Connecticut 
August 28, 2011
Answer
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.

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
Ayad Bakir 
from Illinois 
June 08, 2011
Answer
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.

Would this pump be suitable for a 12' x 12' basement?
Cody Dix 
from Ohio 
January 10, 2011
Answer
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.
