Customer Questions & Answers

I already have a backup sump pump system. My main pump broke. Is it easy to install this pump to my backup pump?

Asked by: Amy
See my comments on this. I assume that you have the Watchdog backup pump, and this is a direct replacement for it. Make sure that it is the correct size (1/3 or 1/2 HP) for their different models. (If the 12v pump is yellow, it is 1/3) If it is not Watchdog, you will have to take measurements, of course.

how does this pump start andstop
Asked by: ron
The BW1033 pump comes with a BWC1 Dual Float Controller and Switch. The pump plugs into the socket on the controller portion. When both the switches are in their original downward position, there is no power coming through this socket. The switch portion of that device consists of two floats, which are buoyant discs on a stem inside a cage. When the water level reaches these discs, they float. When either of the discs is lifted ¼ inch the BWC1 system allows power to come through the socket on the controller portion. When this power comes out to the pump that is plugged into it, the pump will start up. After both of the floats are in their downward position, the controller will continue to output power to the pump for an additional 10 seconds, and then cut off power to the socket, stopping the pump.

Can a garden hose be hooked up to pump for water removal. During heavy rains, sometimes water will back up onto patio, a pump is necessary to keep water from reaching house.
Asked by: Cmele
We highly recommend using 1 ½” PVC pipe for that pump, but yes you can purchase a pipe adaptor and a reducer and connect it to a garden hose if needed. Keep in mind this will decrease the overall pumping capacity. For more information, please contact our customer support team at 800-991-0466, option 3. We are available to take incoming calls from 9am - 5pm CT Monday through Friday.

In shallow basin to avoid sucking air could you reduce the pipe size or throttle it with a valve during 10 sec run time?

Asked by: R2D2
Give us a call Directly at 800.991.0466 EXT 3 there may be some better options other than reducing the size of the pvc. It would be best if we talked to you and got a better understanding of your set up so that we can answer all of your questions and give you the best advice. We are open M-F CST 9-5

1/3 HP Submersible Sump Pump is rated 4.2 out of 5 by 13.
Rated 5 out of 5 by from In addition to being a standalone pump, this is also used as a replacement for the Watchdog combo... In addition to being a standalone pump, this is also used as a replacement for the Watchdog combo (battery backup) primary pump. More or less, it went right into place, but a few hints if that is your purpose for the purchase:: 1) You may have to move the power cord to the other side of the handle. The 12v pump's bracket goes into the side where the cable was on mine. 2) Don't use this in a sump-well that is also used for the brine discharge from a water softener. It took seven years, but the brine actually desolved the walls of the pump. The motor and switch still worked, but the water just swirled around. 3) Make sure that you can get the adapter/back-flow valve off of the old pump. They seem to glue it in at the factory, and, no matter which tool that I used, it would not budge. I finally took a hammer to it, and, owing to the degraded condition of the pumps body, it broke and I was able to get the adapter out, clean the threads and re-use it, other wise, order a new one from the manufacturer, as nothing else is available that will fit the right way. 4) Their tech support is friendly and excellent.

Rated 5 out of 5 by from great "little" pump I have a lot of ground water in the spring and my pumps goes off 2-3 times a minute so I burn our switches and sometimes pumps often. The sump area is plenty deep enough but narrow enough to make putting two full sized pumps difficult. I had a battery backup pump that was small but that finally went. Since I have a whole house generator I started looking at 120v pumps that could fit and found this one. It's only 6" in diameter and the switch can be centered over the pump so in no way interferes with my 3/4hp pump. Plus the 1/3 hp 2200gph means that it will keep up even in the spring. This is the only one i found that had the water exit out the top and a float that wouldn't interfere with the float on my second pump.... great idea....

Rated 5 out of 5 by from Small footprint, fast, quiet, good value My old pump ran every 15 minutes for 6-7 seconds, rain or shine, winter or summer and lasted 6-1/2 years. I replaced it with a new Basement Watchdog pump that only runs every few hours. The new pump is much quieter and the water does not hammer the check valve like the old 3/4 HP Flotec. Also saving on electricity, the new pump uses 3.5 amps the old one used 7 amps. With my very active rusty water sump, only time will tell how long this new pump will last. The only con I could find is the non-adjustable run time. Because of the fixed 10 second run time I had to mount the float higher then the recommended height (the upper float trip is above the drain pipe), so that the pump would not run dry.

Rated 5 out of 5 by from Keeps the water out Simply to install and works better than I expected. The on and off float is GREAT!

Rated 5 out of 5 by from Works Great, Quiet. My old sump pump was failing and I had already purchased a Watchdog battery powered sump pump. Installation was a breeze. The new 1/3 HP sump works great. Very strong, very quiet. I really like the top discharge.

Rated 3 out of 5 by from Great long as it lasts Pump lasted 3 months in a sump with very little 'run time'. Replacement pump was shipped within hours and received within 3 days. The replacement is running now. Time will tell how long this one lasts.

Rated 1 out of 5 by from Defective out of box I bought this back in March to back up my still-working sump pump in case it failed. We had a wet spring/early summer so I let the old one keep going. Fast forward to July and I just installed it and it doesn't work, won't even pump water out of a 5 gallon bucket. Just sits there and hums when directly plugged in to outlet in "continuous duty" mode. I was able to reinstall my old pump with no trouble, but unfortunately I'm beyond the 90 day HD return period so I have to pay to ship this defective pump back to the manufacturer. Moral of the story - test your pump in a bucket right away even if you're not ready to install it immediately!
