About This Product
Designed as an Easy-To-Install, Do-It-Yourself backup sump pump, it includes a back-flow preventer and battery powered high water alarm. The pump is mounted on the ceiling, keeping it clean and dry until needed and uses water pressure to pump water. This design meets most local plumbing codes for back-flow prevention, includes many of the installation parts, and means greater efficiency and higher pumping rates. It connects directly to your home water supply, using push-fit pipe fittings for copper, PEX, or CPVC piping. Suitable for use with Radon covers. This model includes a brass dual check valve, brass shutoff valve, and a push-fit tee and adapter, so it is easy to install right out of the box.

Questions & Answers
how many horsepower is the RB 750
Pumps are not rated in horsepower. Motors or spinning shafts are rated in horsepower. I know that many pump manufacturers call out the horsepower of the motors they use in their pumps but there is only tangential relationship with motor HP and how much fluid the actual pump will move or how high it will pump. The horsepower ratings have always done more to confuse and misrepresent more than help. But one manufacturer did it and all felt the need to follow. This is a water driven pump, so it has no motor and therefore there is no horsepower rating. Water driven pumps are powered by a combination of water pressure and water volume. Assuming you can provide the pump with a flow rate of 7 GPM at a water pressure of 40 PSI the unit will pump 700 Gallons per hour. The same volume at 60 PSI will pump 750 Gallons per hour. At 80 PSI the output jumps to 800 Gallons per hour. If from a desktop computer, you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find PDFs of the product documents. They outline this and additional information.
How much water does it use to pump out water in the catch basin?
The efficiency of all water driven sump pumps is about the same and it depends on the water pressure. The higher the water pressure the more energy it contains. When supplied with a 40 PSI water source the ratio is roughly 1:1. You use one gallon of water to pump out one gallon of water. At 90 PSI you will typically achieve a 2:1 ratio. For every gallon of water used you will remove 2 gallons from the sump.
what size is water inlet to the backflow preventer
If from a desktop computer, you scroll down the Home Depot product listing page you will come to a section entitled Product Details. When you expand that section, you will find PDFs of the product documents. The brochure shows that the connection to the backflow preventor is ¾”
What is the size of the ball float and how much room does it require to move properly?
The ball float is approx. 5" in dia. and requires 2" upward rise to operate the pump
The installation instructions require the pump to be installed on the ceiling joists, which is about 10 feet above floor. Can I install pump at a lower height on the wall (say about 4 or 5 feet) instead?
Yes, the Basepump can be mounted lower than our recommended ceiling joist location. Please keep in mind that water power pumps are suction generating devices and perform best when they do not "push" water on the discharge. So keep the discharge elevation as short as possible
will this work with a pedestal style sump pump?
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.
does this work with 18" deep sump pit ? is there a minimum depth requirement ? primary pump is Zoeller and it works well.
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.
Is this model Basepump RB750-EZ?
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.
