"Ask for it by name"
Basepump is an extremely reliable, very powerful, water powered backup sump pump system. With no battery to wear out or maintain, no charger to plug in or monitor, it is designed as an automatic, independent system from the primary sump pump. Basepump is essentially in a class by itself. Mounted on the ceiling, high above the sump, it doesn't have to fight the downward force of the water that most competitors' pumps must push up vertically. For this reason, Basepump consistently removes more water per hour than other water powered backup sump pumps and even rivals the best battery powered backup sump pumps, short- and long- term. Period. So instead of a flooded basement because of a sump pump failure or a power failure, install a water powered Basepump backup sump pump before it happens.
When the water in your sump rises above normal for any reason, the Basepump float is lifted. This activates a valve, sending municipal water under pressure through the Basepump Ejector. Then, acting like a giant soda straw, it draws the sump water up and ejects it to the outdoors. As the float returns to its lowest level, the pumping stops after a preset period of time, draining the sump down until the water rises above normal again and the cycle starts all over again.

This chart simply means that if you have the given water pressure in your home, with all faucets and Basepump turned OFF, the pumping rates shown in this chart are the rates you should expect from the model you choose. The pumping rate in your home may vary depending on factors such as restrictions in your water lines or long discharge pipes.
Included Water Alarm
"How do you know what size to buy?"
Two primary factors, other than money, influence this decision. Typically you determine the pumping NEED first and then determine how large a pump your water supply in your home can support. Here's how you do that:
- Your pumping need: How often does your electric sump pump run during a fairly rainy period Generally speaking:
If the time between pumping cycles is more than 4 minutes then you would probably need an RB750.
If the time between pumping cycles is less than 4 minutes then you would probably need an HB1000.
If the time between pumping cycles is less than 2 minutes then you would probably need a CB1500; this model is rarely used in residential homes. The reason will become clear in the next section.
Now that you've answered that question, do this simple test:
- Your pumping capability: How much pump is your municipal water supply capable of running?
To calculate this, do a 5 Gallon Bucket Test. It's simple and easy to do and requires no special equipment: just a bucket and a watch.
Fill a 5 Gallon bucket to the 5 Gallon Level as quickly as you can at your standard outside hose spigot, without the hose, and time it with a watch or stopwatch.
If you can fill 5 gallons in less than 40 seconds, the RB750 will work.
If you can fill 5 Gallons in less than 30 seconds, you may use the HB1000 or the RB750.
If you can fill 5 Gallons in less than 20 seconds, you may use the CB1500, or the HB1000, or the RB750.
Now put your pumping need, #1, together with your pumping capability, #2, and you have the answer; you can use a smaller pump than the bucket test shows, but not a larger one, even if your "pumping need" appears higher. There are a few exceptions to be aware of as seen here: 5 Gallon Bucket Test, as shown on our Homeowners Page.
Once you have the answers to those two questions, all the rest is about installation.

- Discharge relief tee to provide back-pressure and to keep pump running even when the drain is plugged.
- Cable tie nylon straps to keep things neat.
- PVC fittings to connect your suction and discharge piping.
- Flexible PVC discharge hose, 6 feet long, to help make the discharge piping easier.
- Float assembly to operate the ejector valve.
