Flojet RV Water Pump Strainers: Barb, Threaded & Quad Ports
A Flojet inlet strainer helps keep sediment and debris out of the RV's freshwater pump. These six 1740-series products use 40-mesh stainless-steel screens, but have different fittings. The key choice is whether the pump needs a straight inline strainer or a 90-degree strainer that plugs into a compatible Quad port.

Where the strainer is installed
Freshwater supply
Water travels from the RV tank or other approved freshwater supply toward the pump.
40-mesh strainer
Installed upstream of the pump to collect debris before it reaches the pressure-switch and valve components.
Pump inlet
The chosen hose-barb, thread or Quad fitting must match the installed pump connection.
Downstream RV fixtures
The pump sends pressurized freshwater toward sinks, showers and other approved fixtures.
A hose-barb fitting needs correctly sized hose and clamps. A male pipe-thread fitting needs a compatible threaded connection. A Quad-port outlet must engage the correct Flojet snap-in inlet; similar-looking strainers are not automatically interchangeable.
Before fitting or cleaning a strainer
- Read your installed pump's inlet design and compare both ends of the original strainer, not just the hose diameter.
- Disconnect the pump's power and release water pressure before removing the fitting.
- Keep the clear bowl accessible for cleaning and use the correct seals or retaining clips for the connection.
- After installation, restore water and power and check carefully for leaks, air entering the inlet and proper pump operation.

A strainer protects the pump from larger particles but does not disinfect or purify water for drinking. For service of the matching pump body and pressure switch, consult the manufacturer's documentation for your exact pump model.
