W1315000 RV Fresh Water Tank Fittings Installation & Options

The fitting dimensions alone do not establish an approved installation method for this W1315000 tank. Identify the manufacturer and exact part number of each flush fitting, fill connection and sensor, plus the tank material, wall thickness and intended fitting locations. The original question's two 1/2-inch FPT connections, fill-tube OD/ID and four sensors are not exact part identities or drilling instructions.

A fitting designed for spin welding must be installed by its manufacturer's specified process with compatible tank material and the correct driver and tooling. Custom Plastics' process guidance describes friction welding compatible materials; it does not approve gluing these unidentified fittings into this tank. Do not substitute sealant or adhesive for a required weld. A bulkhead or grommet fitting is a different design and needs its own approved hole, wall-thickness, access and sealing requirements; a universal kit is not an automatic alternative.

The current W1315000 listing is the blank-tank catalog reference. Its retained drawing is marked W1315001, revision B, and shows a configured assembly; that is not proof that the blank tank is supplied with those openings or that the pictured sensor/fitting layout applies to this installation. Confirm the exact blank-tank drawing and the fitting manufacturers' installation requirements before drilling or altering it.

The historical SPINWELD service card below is a reference only. This Page does not establish that fittings have shipped, were installed separately, that installation service is available or paused, or that a completed joint will be leak-proof. Have the exact layout and method confirmed by the tank/fitting manufacturer or a qualified tank installer. No fitting installation, service restart, shipment or leak-test outcome is promised here.
