Flojet Water Pump Mini-Strainer | 01740300A | 40 Mesh | Quick Connect

Protect your Flojet RV water pump from debris-induced failure with the Flojet 01740300A Water Pump Mini-Strainer. This compact inlet-side filter sits between your freshwater tank and your Flojet pump — catching dust, dirt, sand, and debris before they reach the pump's internal components. With a 40-mesh wire screen, quick-connect installation, and a clear viewing window for at-a-glance monitoring, this is the kind of small accessory that prevents the expensive failure: a clogged or damaged pump from contaminated freshwater supply.

What This Strainer Does

The Flojet mini-strainer is preventive protection for your water pump:

• Filters incoming water from your freshwater tank or supply line
• Catches debris before it reaches the pump — dust, dirt, sand, particulates
• Prevents premature pump failure from contaminated freshwater supply
• Mounts on the inlet side (between freshwater source and pump)
• Allows visual inspection via the clear viewing window

Real-world relevance: campground freshwater connections often carry sediment, sand, or rust particles from aging infrastructure. RV freshwater tanks can also accumulate debris over time, especially with infrequently-cleaned tanks. Without an inlet strainer, all that debris travels straight into your pump's internal mechanism — accelerating wear and shortening service life.

For Flojet Pumps with Quad Port Fittings

The 01740300A is designed for use on the inlet side of Flojet pumps or any device using quad port type fittings. Specifically compatible with:

• Flojet Triplex pump: 52673
• Flojet Quad II pumps: 52675, 52681
• Flojet 03526 series pumps
• Flojet 4406 series pumps

If your pump uses quad port type fittings, this strainer is a likely fit. Verify your existing pump model and fitting type before ordering.

⚠️ For Flojet Pumps — Not Shurflo or Other Brands

The 01740300A is specifically designed for Flojet pumps. While the general concept of inlet-side strainers applies to all RV water pumps, this specific strainer's fittings and dimensions are matched to Flojet's pump architecture. If you have a Shurflo, Aquatec, or other non-Flojet pump, this strainer will NOT be the correct fit — those pumps use brand-specific strainer designs with different fitting standards.

Perfect for RV Poly Tank Connections

The 01740300A is particularly well-suited for RV applications where the pump draws from a poly freshwater tank:

• Keeps debris from poly tanks from entering the pump inlet
• Standard RV freshwater setup compatibility
• Compact size fits in typical RV plumbing compartments
• Easy access for routine cleaning

For most RV installations, this is the standard inlet protection that pump manufacturers recommend (and many require) for warranty coverage.

40 Mesh Wire Screen — Effective Filtration

The 01740300A features a 40-mesh wire screen:

• Catches small particles — fine enough to protect pump internals
• Wire construction — durable, doesn't degrade over time
• Won't shred or fail like cheaper mesh alternatives
• Standard mesh size for RV pump inlet applications

Removable Screen with Clear Viewing Window

The 01740300A is designed for easy maintenance:

• Removable screen — click the tabs to release the mesh
• Clear viewing window — visually monitor debris accumulation without disassembly
• Quick visual check during routine maintenance walks
• Easy cleaning — rinse the removed screen and reinstall

The clear window in particular is meaningful for ongoing maintenance — you can quickly check whether the strainer needs cleaning without taking the system apart.

Quick Connect System

The 01740300A features a quick connect system — simplifying installation and removal:

• Fast installation on compatible Flojet pump inlets
• Tool-free disconnection for cleaning
• Secure connection that holds under operational pressure
• Reduces installation complexity vs threaded fitting alternatives

Specifications That Matter

• Maximum Flow Rate: 3.5 GPM
• Maximum Pressure: 15 PSI
• Mesh Screen: 40 mesh wire
• Dimensions: 6.8" × 5.1" × 2.5"

⚠️ Pressure Rating Note

The 01740300A is rated for a maximum pressure of 15 PSI. This is the inlet-side pressure rating — the strainer sits BEFORE the pump in the freshwater flow path, where pressure is from tank head (gravity) rather than pump output. The 15 PSI rating is well above typical inlet-side pressure for RV poly tank applications. For installations where shore water pressure exceeds 15 PSI on the inlet side (unusual), a pressure regulator should be installed upstream.

Maintenance Best Practices

To get the longest service life from both your strainer and your pump:

• Check the strainer monthly via the clear viewing window
• Clean the screen quarterly or whenever you see significant debris accumulation
• Replace the screen if it shows damage or excessive scaling
• Inspect annually as part of broader RV plumbing maintenance

When You Don't Have a Strainer Yet

Many RVs ship without inlet-side strainers — especially older models, budget-tier RVs, or DIY plumbing installations. If you're running a Flojet pump without inlet protection, adding this 01740300A is one of the most cost-effective preventive maintenance upgrades you can make. Pump replacement costs many times more than this strainer, and a single significant debris event can damage the pump beyond repair.

⚠️ Installation Notes

Installation is generally a DIY-friendly job for owners comfortable with basic plumbing work. For first-time installations or unfamiliar pump configurations, a qualified RV service technician can ensure proper fitment, leak-free connection, and verification that flow direction matches the strainer's design orientation. The strainer must be installed in the correct flow direction (water flows IN through one port, OUT through the other — verify the orientation per the included instructions).
