GROCO 1-1/4" Fresh Water Strainer w/#304 SS Basket

The GROCO 1-1/4" Fresh Water Strainer with #304 stainless steel basket is engineered to protect fresh water system pumps from sediment, debris, and contaminants that can cause cavitation, reduced flow, and catastrophic pump failure. Whether you're running a marine auxiliary system, RV water supply, or any pressurized fresh water circuit, this strainer acts as the first line of defense by capturing particles before they reach critical pump components. A quality strainer is non-negotiable for system longevity—neglecting one invites expensive repairs and downtime.

Built with a white nylon strainer head and clear plastic sight glass, this unit allows you to visually inspect filter saturation without breaking down the system. The #304 stainless steel basket resists corrosion in saltwater and freshwater environments, maintaining structural integrity and flow characteristics over years of service. The 1-1/4" port size handles moderate flow rates typical of auxiliary and deck wash systems, while the unscrewing design of the sight glass makes basket cleaning straightforward—simply unscrew, rinse the basket free of trapped sediment, and reinstall. Compact dimensions (4 x 4 x 6 inches) and 1-pound weight make integration into tight engine compartments or utility spaces practical.

Marine technicians, RV owners, and system builders rely on this strainer to prevent costly downtime and pump replacement. Install it upstream of your fresh water pump, ideally in a location where the sight glass remains accessible for routine inspection and maintenance. Compatibility extends to any 1-1/4" NPT port on standard fresh water distribution systems; verify your pump inlet and plumbing fittings before ordering to ensure a direct fit. Regular basket cleaning—especially after initial system fill or after extended storage—ensures peak performance and maximum pump service life.
