How Basepump
Works:
 |
Basepump
Ejector is mounted on the ceiling joist above the sump, unaffected by scale,
corrosion, clogging, or debris. |
|
A PVC
pipe with a screen on the end extends from the Ejector down into the sump. |
|
For Outdoor Installation the separate discharge pipe
from Basepump goes directly outdoors through a hole in the wall. |
|
For AVB installation, the separate
discharge pipe slopes down and away from Basepump for free-flowing
drainage. |
|
For Indoor Installation the discharge pipe from the main pump is used
by Basepump for it's discharge pipe. |
|
A float is
mounted in the sump pit above the normal high water mark. Under
normal conditions, your main electric powered sump pump will handle all the pumping
duties. |
|
When
water rises higher than normal for any reason, the Basepump float
in the sump is lifted
and hydraulically activates the Basepump Ejector on the ceiling
through a pressurized plastic tube. |
|
As
municipal water rushes through the ejector, it creates a powerful suction force
which causes the PVC pipe to act like a giant soda straw,
drawing water up from the sump and ejecting it outdoors.
|
|
As
the water level falls, the float drops back down and a pre-set timing control
keeps the ejector running for about 30-45 seconds
before shutting off the system. This allows a full pump-down of
the sump, unlike some other pumps. |
|
No impellers,
turbines, motors, or mechanical parts
to wear out.
|
|
No batteries,
wires, or chargers to monitor, tend to, or replace. Ever!
|
|
Fully automatic
operation. Works whether you're home or away, for as long as it is
needed. |
|
Basepump can
supplement the primary pump when water flow is excessive. |
|
Installs
and performs
independently from the primary sump pump system. |
|
Reliable, heavy duty, and durable. |
|
Discharge
Relief Tee keeps Basepump working in cases when the discharge pipe
becomes frozen or clogged. |
|
Easy,
step by step, illustrated instructions are included. |

| Take a look at the various features of several water powered backup
sump pumps currently on the market. The information on our competitor's
models comes directly from their published information and we do not
take responsibility for their figures. All we are doing is reporting
them and giving you, the consumer, an easy-to-use comparison chart to
make your decision process easier. We hope this helps. After all, it's
not just about price. It's also about Quality. |

water usage figures are given using
10 Foot Lift and 50 PSI average water Pressure (unless noted)

When comparing, it is
essential to do your best to compare accurately.
| Manufacturer: Base Products
Corporation specializes in Backup Sump Pumps. It's not a sideline
for us. |
| Sizes: Three models to choose
from: Essentially "Small", "Medium",
"Large". |
| Pumping Rates: Basepump has the
highest pumping rates in the industry. |
| Efficient use of water: 1 Gallon
of city water removes 2 Gallons of sump water, at 10 feet and 60 lbs
PSI. |
| Easy-to-Use installation kits are
available for the water supply and the suction and discharge. |
| Water Alarm: Included with every
pump to warn homeowner of high water. |
| Small Sumps: Basepump only needs
a small area of the sump in order for the float to operate. |
| Float Action: Reliable hydraulic
operation with no moving parts and NO electrical parts. Adjustable for pumping down the
sump. This is key when comparing pumps. You don't want a pump that
turns on and off quickly or one that only maintains a water level.
You want one that can empty the sump on each cycle. |
| Radon Cover: Basepump can be
installed safely in a sump that has a sealed Radon Cover. |
| Warranty: Longest warranty in the
industry. We stand behind what we make. |
| Cycles: Basepump can be set to
run long enough to pump down the sump each time before turning off. |
