This is my second Watch Dog I have had like this. It is great the other one saved me from getting my basement flooded 4 times. Put a price on that. I had it for so many years I can't begin to remember when I got it. So when it died I went right after another. I have praised this pump to anyone who will stand still and listen to me.
Please with the overall solution, several hours to install but the instructions are very good.

Very pleased with unit & service

This was recommended to me by my plumber, who installed the unit. I am very pleased with it so far. The warning light was on once & I just had to reset it. It indicated that it went on during a power outage. I had occasion to call the company with a question & the tech connected me with management who were so helpful & explained in detail their answer to my query. 6 mos. of usage & it has saved me several times from a flooded basement.
Can't ask for a better back up sump pump

Can't ask for a better back up sump pump. Gives you all sorts of warnings, when it goes off, battery low, power loss. I have finally replace our old watch dog after 12 years. A must when your sump pump goes off every 15 minutes in the spring and early summer time.
Great for emergency, occasional use

I have a garage that occasionally will flood during heavy rains because the garage is at the end of the driveway and the garage end of the driveway is about 5 feet lower than street level. Such flooding would occur 1 or 2 times a year and would last for less than 1/2 hour. I needed a pump that would turn on automatically when water was present, had a battery backup and would tell me that it had activated. This unit does all this and has worked flawlessly for almost 2 years now.
