SHURflo 255 Water Pump Strainers — Connection & Parts Diagram
SHURflo's 255-series strainers sit on the inlet side of compatible fresh-water pumps and keep sediment away from the pump mechanism. All four versions use a removable clear bowl and a 50-mesh stainless-steel screen. The main difference is the inlet fitting and how the strainer attaches to the pump. Use the connections on your existing setup to select the correct one.

SHURflo 255 strainer components — exploded view
The manufacturer's drawing identifies four parts inside the strainer assembly:
- Top housing: contains the water-line and pump connections.
- Gasket: seals the removable bowl to the housing.
- Screen: traps sediment and can be lifted out for cleaning.
- Clear bowl: catches debris and lets you see when cleaning is needed.

Cleaning the strainer
- Switch off power to the fresh-water pump and relieve water pressure.
- Unscrew the clear bowl counterclockwise and remove the screen.
- Rinse debris from the screen and bowl, then check the gasket and housing for damage.
- Return the screen to the top housing, seat the gasket in the bowl and screw the bowl back on clockwise. Check for leaks after restarting the system.
Install the strainer on the suction side of the pump, never on the pressurized outlet line. Pentair specifies a maximum liquid temperature of 120°F (48°C) for this series. See SHURflo's installation and maintenance instructions (PDF).
