Crosswater DV416FA1 Diverter Mechanism from DE416FC

SUMMARY

Crosswater DV416FA1 Diverter Mechanism with Chrome Cap for DE416FC and PRO416FC Bath Shower Mixers

The Crosswater DV416FA1 is a diverter mechanism with a chrome cap for selected Crosswater floor-standing bath shower mixers. It is used in the Crosswater Design DE416FC and MPRO PRO416FC models, controlling the diversion of water between the bath spout and handheld shower.

The diverter mechanism allows water to be directed to the required outlet without replacing the complete bath shower mixer. A worn or damaged diverter may cause difficulty switching between the bath and shower outlets, water passing through the unintended outlet or the diverter failing to operate correctly.

Common Problems and Troubleshooting

Symptom: Water does not divert correctly between the bath spout and shower handset.

Likely Cause: The diverter mechanism may be worn, damaged or unable to operate correctly.

Solution: Inspect the existing mechanism and its seals. If the diverter is faulty, replace it with the correct part for the mixer.

Symptom: Water continues dripping from the bath spout or shower handset when the mixer is turned off.

Likely Cause: The main mixer cartridge may be worn or failing to shut off the water completely, rather than the diverter mechanism itself.

Solution: Check the main mixer cartridge and identify the source of the leak before ordering replacement components.

Before Ordering

Confirm that your bath shower mixer is the Crosswater DE416FC or PRO416FC model. Compare the removed diverter with the dimensions listed above, paying particular attention to the fitting thread, upper thread, overall height, operating cap and sealing arrangement. Other Crosswater bath shower mixers may use different diverter assemblies, and matching dimensions alone do not establish correct fitment.

Installation Notes

Isolate the water supply before dismantling the mixer. Inspect the diverter housing and sealing surfaces for damage or debris. A small amount of suitable silicone grease may be applied to the O-rings and seals during installation to help prevent twisting or damage. Ensure the mechanism is correctly fitted and test both water outlets after reassembly.
