Product Information

Full details

The Roma Caravan Shower Mixer Water Tap is designed for caravan and motorhome owners seeking a durable, domestic-style fixture for their mobile water systems. It provides the key benefit of precise flow and temperature control through a high-quality ceramic cartridge, making it an excellent upgrade for standard RV taps; however, installers should note that it requires a minimum mounting hole diameter of 33mm, which may necessitate modifications if replacing smaller, legacy fixtures.

FAQs

Does this tap work with high-pressure home systems?

This tap is specifically designed for caravan and motorhome systems; it is not recommended for high-pressure residential mains water.

Can I install this on a thin countertop?

Yes, as long as the counter is sturdy enough to support the base diameter of 50mm, though you may need a backing plate if the material is too flexible.

Is the hose replacement standard?

The hose is integrated into the Roma system; always use manufacturer-approved parts for replacements to ensure compatibility.

What happens if the internal cartridge fails?

The ceramic cartridge is a replaceable component, which helps extend the overall lifespan of the tap unit.

Do I need a transformer for the 12V switch?

If your caravan already has a 12V system, the switch simply acts as a trigger; you do not need an additional transformer.

Troubleshooting

Water flow is restricted

Check the pull-out hose for kinks underneath the counter or inspect the 10mm barb connections for debris.

Tap handle feels loose

Check the mounting nut underneath the surface to ensure it has not vibrated loose during transit.

Pump does not start when handle is lifted

Verify the electrical connection to the micro-switch and ensure all spade connectors are tight.

  • Compatible with both pressurized and micro-switched pumps
  • Generous 1500mm pull-out hose length
  • Compact 120mm height fits most caravan cabinets
  • Precision water flow control

Setup, Compatibility & Care

Installation requires a 33mm mounting hole and a flat surface area of at least 50mm in diameter for the tap base to sit securely.

  1. Ensure the water system is depressurized before beginning installation.
  2. Pass the hoses through the 33mm hole and secure the base nut underneath the counter.
  3. Connect the 10mm barb fittings to your existing water lines using appropriate clamps to prevent leaks.
  4. If using a micro-switched system, ensure the electrical connectors are wired securely to your pump circuit.

For maintenance, wipe the exterior with a soft, damp cloth. Avoid harsh abrasive cleaners that may scratch the finish. During winterization, ensure the tap is opened and fully drained to prevent freezing damage to the ceramic cartridge.
