A: This product does now work in concert with or communicate with other pumps on the job site. It is installed in parallel with them. It is typically installed so that it turns on at a water level higher than that of the primary pump. This way if the primary pump either does not come on or can’t keep up, the rising water level will then turn on this pump as supplemental or replacement capacity. Therefore the fact that you have a pedestal pump does not definitively tell me that this product is or is not appropriate for your application. To know if this pump could effectively be installed in parallel with your pump I would need to be on sight; as every installation is different. For a definitive opinion you would should as a qualified local licensed plumber to take a look. I can share with you that I do not like pedestal pumps due to the danger of electrical shock if they tip over. Before I spent money on a water actuated back up pump, I would invest in a quality submersible pump to replace the pedestal unit.
A: This product can work in as little as three inches of water. The float has a two inch range of motion and then we are adding one inch of water depth below that. With your installation I would do the fallowing. I would find out the water level at which the primary Zoeller brand pump comes on. Then I would install the float for this pump so that it comes on if the water level gets one to two inches beyond that. Why? You want the the Zoeller pump to be the primary pump. You only want this back up to come on in the even the primary pump fails or can't keep up.
A: The model number for this pump is RB750-EZ. You will see the model number in the upper right of the Home Depot product listing page.
A: The notion that the pumps would recognize each other assumes there is a built in intelligence that allows them to be aware of each other and to work in concert. That is not the case. The logic is much more simple. The primary pump is typically installed in the bottom of the sump. The water driven pump is installed above it. As a result when the sump fills the primary pump is turned on first. If it fails to pump or lacks the capacity, to keep up, the water will continue to rise. When this occurs the water will eventually actuate the float for the second pump. Another way to describe this is your thought the pumps were installed in parallel. They are not. They are installed in series. If you look at he videos on the Home Depot product listing page this is shown.
A: Yes. It has its own float that turns it on. It also has a battery powered high water alarm so you know if there is a problem.
