Designed with advanced impeller resistance technology, this 12V pump automatically detects water levels between 1\/8\" and 3\/8\" without the need for a float switch. It activates every 2-1\/2 minutes to check for water, ensuring continuous protection against bilge flooding while conserving power. When water is detected, the pump runs until the bilge is dry, then resumes sensing, making it ideal for efficient water management on boats and vessels.\u003c\/p\u003e\u003cp\u003eConstructed for durability and safety, the Rule 20SA features a stainless-steel shaft, high-efficiency low amp motor, and ignition protection, ensuring safe operation even in challenging marine environments. It includes a check valve with a hidden air vent to prevent airlocking and a backflow preventer to stop water from reversing. The built-in thermal switch protects the motor and vessel from overheating, while electromagnetic suppression (EMC) minimizes electrical interference. These compact, automatic bilge pumps are the smallest on the market, providing space-saving installation options without sacrificing performance.\u003c\/p\u003e\u003cp\u003eIdeal for boat owners seeking a dependable, easy-to-install bilge pump that requires no float switches, the Rule 20SA combines advanced sensing technology with rugged construction. Whether used in fresh or saltwater, this pump ensures your vessel remains dry and safe, all while conserving power and reducing maintenance. Please note, this product contains chemicals known to the State of California to cause reproductive harm, as detailed in Prop 65 warnings.
