How Does it Work?


Frequently Asked Question

What happens to your sump pump when the power fails.
With no power the electric pump fails, water can get into the basement and cause costly damage to the water heater, furnace, and anything else in the basement.
 
I have a battery back up for my sump pump, I should be safe shouldn’t I?
A, Battery back up pumps are fine for short power outages, but will it last 4, 6, 8 hours? How about, two days, 5 days, a week?
 
I have my own generator, do I still need the Guardian?
Probably. Think about how much gasoline you have on site and how long it will last in the event of an emergency. Most people have only what is in the gas tank on the generator itself and that won’t last for long? If you run out can you get gas quickly and easily especially if the whole region has no power? Also, are you home 24/7? Do you ever go on vacation?  Who will start the generator if you are not there.
 
How does the Guardian work?
The Guardian uses pressurized city water and a principal called the “Venturi Effect” to create a vacuum and draw in sump water. This is a tested and proven technology. The Guardian has been on the market and performing superbly for years.
