Frequently Asked Questions - EZ100 Global Water
How do I install the EZ100 water pump?
Place the pump in the desired location (sump pit, pond, etc.) ensuring it is on a level surface. Connect the discharge hose to the 1/2 inch outlet. Plug the pump into a grounded 110-120V outlet. The float switch automatically activates the pump when water rises.
What is the maximum head of the EZ100?
The maximum vertical lift (head) is 15 feet (4.6 meters). Flow rate decreases as head increases.
Can the EZ100 pump run dry?
No, running dry can damage the mechanical seal and cause overheating. The pump has a built-in float switch that deactivates it when water level drops too low, but do not rely on it for dry-run protection.
How do I clean the EZ100 pump?
Unplug the pump first. Remove the intake screen and rinse it with clean water. If debris is inside the volute, open the housing (remove screws) and clean the impeller area gently. Reassemble and test.
What is the flow rate at 1 foot of head?
At 1 foot head, the flow rate is approximately 500 GPH (1890 L/h). Flow decreases with higher head.
Is the EZ100 suitable for saltwater?
The pump is designed for fresh water only. Saltwater or other corrosive liquids will damage the internal components and void the warranty.
Does the EZ100 come with a warranty?
Yes, it comes with a 1-year limited warranty from Global Water against defects in materials and workmanship.
Can I use the EZ100 for a fountain?
Yes, it can be used for small fountains, waterfalls, or water features. Ensure the pump is fully submerged and the outlet is properly connected to a fountain kit.
What size hose fits the EZ100 outlet?
The discharge outlet is 1/2 inch NPT. You can connect a 1/2 inch ID hose or use an adapter for larger hoses.
How do I replace the impeller on the EZ100?
Unplug the pump. Remove the screws on the bottom to open the volute. Pull out the old impeller assembly. Insert the new impeller, ensuring the shaft aligns with the motor coupling. Reassemble and test.
