Leaving Room to Open the Strainer Bowl
I used SketchUp to plan the interior and put body openings ahead of the framing, floor and wall panels.
My Interior Preparation notes included the shower drain and openings for three water tanks in that preparation sequence.
I removed cargo tie-down hardware for later framing mounts and door trim for the later insulation and paneling.

My Takeaway for the Build
I planned the tank openings while the interior was still accessible. That same access-first approach is useful for the Shurflo strainer purchase: the clear bowl and removable screen need space around the connection. The alternatives change the housing and end fittings, so service access belongs in the comparison alongside nominal pipe size.

Model
255-313
Screen
50-mesh stainless steel
Ports
1/2 in NPSM inlet and outlet
Bowl
Transparent, removable
The 255-313 sits at the pump inlet to collect debris before it reaches the pump mechanism. Its transparent bowl lets the screen be inspected without taking the whole assembly apart. Pentair identifies this version with half-inch NPSM connections; other 255-series versions use hose-barb or swivel arrangements. That difference matters when matching an existing pump connection. In a camper-van cabinet, the useful planning detail is room to remove the bowl and clean the screen after the surrounding equipment is in place. The linked data sheet identifies the model variants and provides a compact reference for replacement-part selection.
Are All SHURFLO 255 Strainers Connected The Same Way?
No. The 255-313 uses half-inch NPSM ports. Other 255-series models use different inlet or outlet arrangements.
Alternative products
Two Alternatives to Compare
The SEAFLO option uses an inline body with female NPT connections. The larger Shurflo raw-water strainer has a different housing and screen arrangement, so connection type and service space distinguish the alternatives.
