Planning notes

Before you buy
Verify the receiving device can accept the float-valve connection and that the reservoir can be mounted safely above it.
Strengths noted

- A float valve helps maintain a stable receiving-tank water level.
Considerations
- The supply reservoir must be positioned more than eight inches above the receiver.
