Questions & Answers

The specs state that the switch can be set on and off at any height

It appears the float is mounted above the pump. Can the float be set for a lower on and off than the pump height.

I asked this question on 10-01-15 and got an answer on 03-07-16. How does that help you buy a product? I had already bought another product so this answer was no help to me.

Would this pump be suitable for running outside during a heavy rain (to keep a patio from flooding)? I can probably mount the bottom of the pump 3-4" below the concrete level.
Asked by: Mark
As long as the Basement Watchdog Dual Float Controller can be connected inside, and not exposed to the elements, that application would be just fine for this pump. 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.

Need a pump that operates on its own.

Doe this turn on automatically when water is present?
Asked by: DougM
Please note that this pump usually is paired with our dual float switch, which is a piggy back switch which will allow the pump to operate when lifted by incoming water. if the pump is plugged directly into the outlet it will run continuously. If you should have any further questions please contact us at 800.991.0466 ext 3 M-F 9-5 CST

1/2 HP Submersible Sump Pump is rated 4.7 out of 5 by 46.

I can't commit to 5 stars yet because I haven't had it for very long (only one rain so far heavy enough to raise the water to float switch level). This is the only line of pumps that will fit in my sump pit -- my late '50s house has a 7"x7" square sump pit so having the discharge pipe coming off the top of the pump was an absolute necessity. This replaced a utility pump that the previous homeowners had been using as a sump pump, so I'm glad to be able to have something for a permanent installation.

This is a backup pump to a 1/3 hp zoeller. The only issue I have, is once I Added the check valve, the height of the 1.5" pipe was higher than the top of the tank. What watchdod needs is a low profile check valve to make this fit in standard sump basins. The dual float was easy to mount. And when this pump kicks on, it has the power to drain a full basin in less than the 10 seconds it kicks on for. It was worth the price.

Rated 5 out of 5 by from Great little sump pump I really like this unit because it is small and light enough that you can actually suspend it from the bottom of the pit so it doesn't sit in sediment like the heavier units and only last a quarter of their life expectancy. This guy has lasted the longest of any pump I've had. I always keep an extra at home now just in case. The old one lasted 3 years and I would put that up against any bigger unit that sits in sediment. Great pump!

I like that after the water drops below the switch, the pump runs an additional 10 seconds. You get a longer cycle run time versus pumps that turn off and immediately turn back on. Its compact and fits into the sump pit without having to worry if the switch or any other part of the pump is going to interfere with a back up pump or sit correctly in the pit.

Very quiet and low power consumption and also comes with a very dependable float switch. also has a great warranty. I bought this over 3 years ago and just ordered another for backup.
