GROCO 3/4" Fresh Water Strainer w/Plastic Basket

The GROCO 3/4" Fresh Water Strainer with Plastic Basket is a marine-grade intake protection system designed to prevent debris, sediment, and particulates from entering fresh water pump circuits aboard vessels, RVs, and off-grid water systems. The 3/4-inch port size accommodates standard water line connections while the clear plastic sight glass allows visual monitoring of filter saturation without system shutdown.

The strainer head is constructed from white nylon, a corrosion-resistant material suited for extended freshwater exposure. The clear plastic basket and removable sight glass simplify maintenance—unscrew the glass bowl to access and rinse the filter basket, eliminating the need for proprietary tools or system disassembly. A mounting bracket is included to secure the unit to bulkheads, engine bays, or tank compartments with minimal installation complexity. The plastic basket construction keeps the overall weight at 0.6 lbs, reducing vibration in high-movement environments while remaining durable enough for continuous operation.

This strainer is engineered for freshwater applications where pump longevity depends on inlet cleanliness. Cruising sailors, RV water system operators, and off-grid homeowners depend on strainers like this to extend pump life and reduce sediment-related clogs in downstream filters. GROCO offers the WSB-P variant for saltwater or continuous AC/genset duty applications where higher-specification materials are required; this WSB-750-P model is purpose-built for protected freshwater circuits where cost-effective maintenance and reliable debris capture take priority.
