## Questions & Answers

**Q: Can the additional 10 seconds run time be extended, such as 20 seconds and how?**
A: If you know how to solder you can. It's a standard 555 timer circuit. Resister R4 is a 200k ohm. Replace it with a 400k and you'll get about 20 sec. It's linear so for example if you want 30 sec you'd do 600k. I did mine with the existing 200k and in series added a 200k potentiometer so I get a variable 10-20 sec delay. So far so good.

**Q: Mine keeps getting stuck On. The float drops, but the sump continues to run. Any ideas? It is pretty clean..**
A: I did some testing on mine and found something interesting with the relay that turns the pump on/off.  My relay would energize with a minimum of 6.8 Vdc applied across its coil.  To cause the relay to turn off, the applied voltage had to be less than 1.8 Vdc.  This is where I see a potential problem.  That is really close to the voltage that exists during normal operation and would be higher if the line voltage to your AC outlet is higher.  So I could see how the pump could turn on and then never turn off.  Unplug the watchdog, plug it back in, pump would be off but when energized again it would just keep running.  I modified my circuit to make sure the voltage across the relay was about 1.1 Vdc when it was supposed to be off.

**Q: If I use this on the ground at what water level would it activate?**
A: After attaching it to your sump pump you can adjust it to any level however I don't thing it is meant to be used at ground level.

**Q: What hp pump is it rated for? i have a 1/3 hp pump but i don't know if this ill work for my system.**
A: The BWC1 float controller is rated for 12 amps. I'm sure it will run a 1/3 HP pump

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for tight spaces
*by R***S on December 23, 2024*

I really like these electric float switches. I have a sump pump that is down in a deep hole that is not very wide. The problem with normal ball style floats is that in a tight space the ball can get stuck and not float up or fall back down like it is suppose to. The watchdog uses 2 floats in side a little cage. Since they are inside the cage they cant get stuck on their surroundings. The cage can be attached to the side of the pipe as high or low as you like. This allows precise control over the water level.I have used a couple of these Watchdog sump pump switches and I really like them. I would definitely purchase them again.

### ⭐⭐⭐⭐⭐ Piece of Mind
*by A***Y on January 3, 2025*

We had a sump pump fail last year, and the insurance goons required that I devise a backup in order to keep the policy.Well, instead of shelling out hundreds of dollars for an expensive system, I bought this unit and clamped it to the pipe. Then I connected it to a spare submersible pump, and voila! Problem solved.I've had the unit for several months and tested it. It works very well. When water moves the float, the backup pump turns on every time.

### ⭐⭐⭐⭐⭐ So Far so Good, and still good, and a life saver after 7 years!!
*by E***U on March 25, 2011*

So far this unit works perfectly. I have had water issues for many years on and off due to faulty pump switches and switch systems that stick in the on or off position. After doing a lot of research I found that there are no integrated pump switch systems that are completely reliable. Plumbers have fixes similar to this one that cost anywhere from $100 TO $300. But this solution thus far is the most elegantly simple, low cost and about the only thing that I can see that might fail is the electronics that turn the pump timer on and off. I have had this unit in for about 6 weeks and so far so good it works every time.It's been almost a year now and this switch is still working well, it has saved me a lot of worry and I trust it to work every time. As for the 10 second delay that seems to trouble some people, you can easily adjust the height of the float to make sure you empty the sump completely or make sure it doesn't drain before timer shuts down. This is no big deal. I still recommend this product 100%Coming up on 4 years and this product is still working great not 1 single failure!I originally purchased in 2011, 7 years later the back up float system saved me from flooding. The fist magnetic float switch failed and the second one kicked in as advertised and kept the pump working. I noticed one day that the sump hole water level was higher than I had originally set. After some preliminary investigation I realized that the primary switch float wasn't working but the back up kicked in just as designed.I quickly purchased a new unit which arrived in a few days. I just finished replacing the unit and I'm back to normal. I took the time to disassemble the failed float unit (which is easy to do) and I cleaned up all the caked up silt, and once i did this the old float switch unit is working again! Now I have a reconditioned backup. What I learned is that after 7 years of flawless performance, the unit developed some silt/muddy build up that interfered with the magnet sensing on the primary float inside the cage. Once cleaned all was good again. hence if you have one, it worth the few minutes it takes to clean it up once in a while. So now I'm a 7 year test lab with nothing but excellent results. if I could give it 6 stars I would!
