You Should Avoid
Undersizing Pump Capacity
Selecting a pump with insufficient GPH for your vessel size creates a dangerous false sense of security that could prove disastrous in emergency situations.
Ignoring Amperage Draw Specifications
High-capacity pumps with excessive power demands can quickly drain batteries, leaving you without electrical systems when needed most.
Overlooking Installation Requirements
Failing to properly mount, wire, and plumb bilge pumps according to manufacturer specifications significantly reduces reliability and performance.
Neglecting Backup Systems
- Relying solely on an automatic electric pump without manual backup options leaves you vulnerable during electrical failures or battery depletion.
