RV kitchens have to make every inch count. A faucet that works well over the sink may still interfere with a cutting board, storage lid, window, cabinet, or travel cover when the galley is not in use.
The Dometic 3313070-001 Fold-Down RV Galley Faucet is designed with a fold-down configuration and is listed with 12-inch hot and cold hoses in a chrome finish. Its folding design may help RV owners create more usable clearance around the sink and countertop.
The main benefit of a fold-down faucet is not only appearance. It is the ability to manage the space above the sink more efficiently during cooking, cleaning, storage, and travel.

Why Choose a Fold-Down Faucet for an RV?
A fixed faucet can limit how the area above the sink is used. In a compact galley, the faucet may need to share space with:
-
A sink cover
-
A cutting board
-
A storage lid
-
A window
-
A drying rack
-
A dish tray
-
A travel cover
-
A fold-out countertop
A fold-down faucet may help create a more flexible workspace when the sink is not being used.
Potential benefits include:
-
Improved clearance over the sink
-
Easier use of a sink cover
-
More practical counter organization
-
Better access to overhead storage
-
Reduced interference during travel preparation
-
A cleaner appearance in a compact kitchen
The folding mechanism should still be used gently. Do not force the faucet beyond its intended movement or use it as a handle.
Measure the Galley Before Ordering
A replacement faucet should be selected by measurement, not appearance alone.
Check the following areas.
Mounting-hole size
Measure the existing faucet opening and compare it with the replacement requirements. A faucet that looks compatible may still require a different hole size or mounting arrangement.
Countertop thickness
The mounting hardware must fit through the counter or sink deck securely. Thick, reinforced, or unusually thin surfaces may require special consideration.
Sink clearance
Measure the distance between the faucet base, sink basin, window, cabinet, and any cover used over the sink.
Folded height
Check how low the faucet sits when folded. It should clear any sink cover, cutting board, or storage lid.
Hose length
The product is listed with 12-inch hot and cold hoses. Confirm that this length can reach the water connections without stretching, sharp bends, or excessive tension.
Travel movement
Make sure the faucet can remain secure when the RV is moving. The folded position should not allow the faucet to swing into a cabinet, window, or sink cover.
How the Fold-Down Design Can Improve Kitchen Workflow
Food preparation
A fold-down faucet may create more room for a cutting board or sink cover when water is not needed. Keep food preparation surfaces clean and separate from plumbing maintenance tasks.
Dishwashing
After washing dishes, the faucet can be folded when the sink area needs to dry or when the counter must be cleared.
Storage
The additional clearance may make it easier to use a sink cover or place lightweight items above the basin. Items should never be stored where they can fall onto or damage the faucet.
Travel preparation
Before departure, folding the faucet can help reduce the chance of contact with overhead components. Always confirm that the faucet is fully seated and that hoses are not being pulled.
Understanding the Hot and Cold Water Connections
The Dometic 3313070-001 is listed with 12-inch hot and cold hoses. Before installation, identify the RV’s hot and cold supply lines.
Check:
-
Which line comes from the hot-water system
-
Which line supplies cold water
-
Whether the hose connectors match
-
Whether adapters are required
-
Whether the water pressure is within the faucet’s limits
-
Whether shutoff valves are accessible
-
Whether the hoses can be routed without twisting
Do not rely solely on hose color. Verify the plumbing layout before disconnecting the original faucet.

Installation Planning
1. Turn off the water supply
Disconnect city water if connected and turn off the RV water pump. Open the faucet to relieve pressure from the lines.
2. Protect the cabinet
Place a towel or container under the connections to catch residual water. Remove stored items from beneath the sink.
3. Disconnect the old hoses
Loosen the hot and cold connections carefully. Avoid twisting the RV plumbing lines or applying excessive force to the valves.
4. Remove the old faucet
Remove the mounting hardware and lift the faucet from the sink deck or countertop.
5. Clean the mounting surface
Remove old residue, mineral buildup, or debris. The new faucet should sit on a clean and stable surface.
6. Position the new faucet
Place the Dometic faucet in the correct orientation and confirm that the folding movement is clear.
7. Connect the hot and cold hoses
Attach the hoses to the correct supply lines. Follow the faucet instructions for sealing washers, fittings, and tightening requirements.
8. Restore water pressure gradually
Turn on the water supply slowly. Check both connections for leaks before operating the faucet normally.
Avoid Overtightening
A common installation mistake is tightening water connections too aggressively. Excessive force may damage:
-
Threaded fittings
-
Sealing washers
-
Faucet connections
-
Shutoff valves
-
Flexible hoses
-
Countertop hardware
Begin connections by hand to prevent cross-threading. Tighten according to the product instructions and inspect the connection under pressure.
If the faucet leaks after installation, do not keep tightening without identifying the cause. The problem may be a damaged washer, misaligned fitting, cracked hose, or damaged valve.
Testing the Faucet After Installation
Perform a complete test before loading the kitchen.
Check:
-
Cold water flow
-
Hot water flow
-
Temperature adjustment
-
Faucet movement
-
Folded position
-
Base stability
-
Hose routing
-
Cabinet clearance
-
Sink drainage
-
Connections under pressure
Operate the faucet in both raised and folded positions if the design allows it. Make sure the hoses do not pull, kink, or rub against sharp cabinet edges.
Check the cabinet beneath the sink again after several minutes. Slow leaks may not appear immediately.
Protect the Faucet During Travel
A fold-down design can help reduce height, but it does not eliminate the need for travel preparation.
Before driving:
-
Remove objects from the sink.
-
Fold the faucet carefully.
-
Confirm that it is seated in the intended position.
-
Make sure the sink cover does not press against it.
-
Check that the hoses are not stretched.
-
Secure nearby items so they cannot strike the faucet.
-
Inspect the base for movement.
Do not use the faucet as a support point when entering, leaving, or moving around the RV kitchen.
Water Pressure and System Compatibility
RV water systems may use a pump, city-water connection, or both. The faucet must be suitable for the pressure conditions of the installation.
Before use, verify:
-
RV pump pressure
-
City-water pressure
-
Pressure regulator settings
-
Hose and fitting compatibility
-
Hot-water temperature
-
Valve condition
-
Manufacturer limits
A pressure regulator may be necessary in some campground hookups, depending on the RV system and water source.
Maintenance Checklist
Inspect the faucet regularly:
-
Check the base for movement
-
Look for water around the hoses
-
Inspect washers and connectors
-
Clean mineral deposits
-
Confirm smooth folding movement
-
Check for cracks or discoloration
-
Look for hose rubbing
-
Inspect the cabinet below the sink
-
Test hot and cold water flow
Use cleaning products that are suitable for the chrome finish. Avoid abrasive pads that may scratch the surface.
The RV outside shower kit guide includes additional ideas for managing RV water use and keeping outdoor cleaning tasks away from the main galley.
Winter Storage Considerations
Water trapped in the faucet or hoses may freeze and cause damage. Before freezing temperatures:
-
Turn off the water supply
-
Drain the relevant lines
-
Open the faucet
-
Follow the RV manufacturer’s winterization procedure
-
Protect hot and cold connections
-
Check the faucet again before the next trip
Do not apply antifreeze or cleaning chemicals unless the RV and faucet instructions specifically permit the method.
Common Mistakes to Avoid
Buying without measuring
A fold-down faucet still needs the correct mounting hole, clearance, and hose reach.
Connecting hot and cold lines incorrectly
Verify the plumbing layout before installation.
Folding the faucet with force
Use the movement provided by the design. Do not force or twist the mechanism.
Leaving the faucet unsecured during travel
The folded position should be checked before every departure.
Ignoring slow leaks
A small leak beneath the sink can damage cabinetry and flooring over time.
Using excessive water pressure
Protect the faucet and RV plumbing by staying within the recommended pressure range.
Treating the faucet as a grab handle
The faucet is a water fixture, not a structural support.
