Camco Mfg 40003 Water Tank Filler with Shut Off Valve

Product Description

The CAMCO MFG 40003 is a water tank filler with an integrated shut off valve, designed for use in plumbing and water storage applications. The unit features a large 5/8 inch fill tube that helps minimize line backflow during the filling process. It is intended for installation by licensed plumbers and qualified service professionals working on water tank systems. The shut off valve allows the technician to control flow directly at the point of fill, reducing the risk of overfill and backflow into the supply line. This is a straightforward, functional fitting suited for both residential and light commercial water tank service.

The 40003 is used in water tank filling applications where controlled fill rate and backflow minimization are required. The 5/8 inch fill tube diameter accommodates typical tank inlet connections and provides adequate flow volume for standard water storage tanks. This fitting is appropriate for residential water systems, RV water tanks, and similar storage tank configurations where a dedicated fill point with shut off control is needed.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician in accordance with applicable IPC plumbing codes. Shut off the water supply and depressurize the line before removing any existing fittings or installing this unit. Inspect all connection points for proper seal after installation and verify the shut off valve operates smoothly before returning the system to service.
