Product Description

Amazon.ca Product Description

The Basement Watchdog Dual Float Sump Pump Switch with Controller activates your sump pump using a large, protective case-enclosed float that detects a 1/4 in. water level rise. The second float acts as a failsafe that activates your sump pump in the event that the first float does not, helping ensure that your pump drains effectively. Both floats drop easily as your pump runs for an additional 10 seconds to drain excess water, making sump water level maintenance easy. Compatible with most sump pumps, detects excess water rises and activates your sump pump to drain it.

Product Description

Sold as each. 2 floats provide added protection. Protective cage prevents debris from interfering with float operation. Activation height adjustable to any level. 20' float cord. Mounting hose clamp included. Manufacturer's number: BWC1. Country of origin: Taiwan. Distributed by Glentronics, Inc.

Like this over the old float type. No more worries that float will get stuck. Thank you.

I wish there was a setting that you could control as to how long it would run once the high level start was reached.

Works well, good for simple applications... Dec 26 2009
By James Hayes - Published on Amazon.com
Verified Purchase
This pump controller works well for simple applications. The float is well designed, and though "dual float" may lead you to believe that it comes with two separate float assemblies, it's really one assembly with two floats inside. The floats are designed for redundancy. If the lower float fails to signal the pump, you get another chance with the upper float. The key design win here is that the floats are not mechanically linked to the electrical system of the controller. The floats are actually two floating magnets resembling small doughnuts, slid onto a pole running through their centers. The floats, um, "float" freely on the pole, and two magnetic sensors embedded in the pole detect when either of the floats are in the right position to trigger the pump. This is a great design and appears to be *very* reliable. Once the pump is triggered, it runs until the float returns to just below the trigger position, then stays on for a few seconds more. This is good enough to keep a basement sump from overflowing. You could even turn the float assembly upside-down and and create a "auto filler" for use in ponds (or other applications) where the pump is triggered when the water level is too low.

Great for ground-level sump pumps Feb. 25 2010
By Eldho Thomas - Published on Amazon.com
Verified Purchase
I am using this with a sump pump installed on the ground level (without a sump pit). I have installed it for the once-in-a-life-time experience of a sewer backup. So, mine hardly ever wakes up. But, what I like about this switch is that it can be installed very easily. I have it tied to a chair's leg with the bottom touching the ground. I occasionally lift it with a screw driver to make sure it works. I can see that it switches on when the float is about 1/4th inch high.

Don't worry. Be happy. Feb. 18 2009

I can finally sleep without having to worry the float for my sump pump getting stuck. Well worth the money for the peace of mind! I'm amazed I couldn't find this switch in the major hardware stores.

The picture throw me off. I thought it was going to be two separate floats but that's OK.

Works fine; yet another power vampire April 1 2013
By LimehouseBlues - Published on Amazon.com

The basement watchdog arrived today; mounted it on my sump pump, and, behold, it works!


The float unit is 2 inches in diameter and 5 inches tall. It fits in my small sump bucket with room to spare. Nice - other float switches won't work in my cramped space. In the fabulous future of flying cars and robotic maids, I expect sumps to be 18, 20, or even 24 inches across. But for now, I must be content with a 12 inch diameter muckhole.

Even better: the float unit apparently runs on low voltage. This is a good thing, since it'll live around water. When it activates, I hear the guy call out, "Click" ... a sure sign that the wallwart has changed states (well, it stays in California, but perhaps it's yearning to return to its birthplace in Shanghai)

I'm happy with its timer, which keeps the pump going for 10 seconds beyond the float hitting the low end. During this time, my sump-pump slurps the last half inch out of delicious sump-syrup from the bucket.

What's wrong with it? Other pump switch connoisseurs and sump-o-philes will object to its color. It is, alas, all black. Hey - everything around a sump is black: the bucket. the hole. The mud is black. The ABS pipes. And it's the darkest corner of my cellar. Why can't someone make a float switch that shows up when I shine my flashlight there? How about a reflective or white float? Especially, a white cord, so I can see where it's twisted amidst the mud, muck, and debris?

Then, too, this is one big wallwart. A 4x3 inch lump that sticks out two inches from your wall outlet. It weighs a shade under a pound; if you often go hiking with your sump pump, you'll eventually notice this weight in your backpack.

A very useful feature would be a glowing green LED to say that, Yes, power is reaching the switch. This would save time during those all-too-wet emergencies -- is there power getting to that cellar outlet? ? ? Ideally, the light would glow green when the pump is switched off, yellow when the pump should be powered, and red when the planet Saturn is about to collide with Earth.

Sadly, this is a power vampire (even without any LED!). Using an ammeter, I measured it eating 2 watts in standby (which is what it'll do 99 percent of the time). This translates into $3/year for those of us who enjoy the flavorful electricity from Pacific Gas and Electric. So the little guy does not qualify for Energy Star (Level-V requires less than 0.5 watts in standby).

In addition, it's quite silent after the sump has been drained. I'd hoped that it would play a rousing Sousa march during the pump action, and then improvise on a few riffs by Thelonius Monk followed by a Bach cantata with a tromba da tirarsi. No such luck.

Is it good or bad? March 13 2013
By Lucky One - Published on Amazon.com
I bought this dual float switch for my sump pump in 2011. It has worked well until two days ago. The problem was that the pump ran continuously with low elevation in the sump pit. One of the reviewers mentioned this problem. Luckily, I found the problem early enough so my sump pump was not burned out by running dry. But, a strange thing happened. After I shut off the power for about one hour and tested the switch again, the switch was back to normal working condition. My guess is that some of the electric parts inside the controller were malfunctioning after running too long and getting warm. My suspicion was the transistors inside the box(there are two of them). The product warranty is one-year for using the switch to control other brand of sump pump (for my case) so I am out of luck. Although the dual float is very reliable (excellent idea), but the electronics may still be malfunction. Therefore, there is no such thing of 100% trouble free for a sump pump system.
