GROCO 1/2" Fresh Water Strainer w/Plastic Basket

The GROCO 1/2" Fresh Water Strainer with Plastic Basket is engineered to protect fresh water pump systems from debris, sediment, and particulate contamination. Designed for marine, RV, and off-grid water supply applications, this strainer acts as a critical pre-filter that extends pump life and maintains consistent water flow. Marine plumbers and system integrators rely on this unit to prevent costly pump damage caused by sand, scale, and foreign particles common in untreated water sources.

This strainer features a white nylon strainer head paired with a clear plastic sight glass, allowing operators to visually assess filter loading without disassembly. The removable plastic basket traps debris while maintaining optimal flow rates through the 1/2" port connection. The transparent sight glass design enables quick condition checks during routine maintenance, and the basket unscrews for straightforward cleaning and replacement. The plastic construction resists corrosion in saltwater environments and freshwater systems alike, making it ideal for marine and coastal installations where metal components would degrade.

This strainer is best suited for boat water systems, RV fresh water tanks, cabin water supplies, and any 1/2" potable water line requiring debris filtration. The compact 5 x 3 x 7 inch profile fits easily in engine compartments, under-sink locations, and tight installation spaces. Installation requires standard 1/2" NPT or compression fittings depending on your plumbing configuration. Regular basket inspection every 50–100 operating hours ensures reliable protection; replacement baskets are readily available for extended service life.
