Space is limited in an RV kitchen. A faucet that works well in a residential kitchen may extend too far over a compact sink, interfere with a cover, or prevent the galley area from being secured for travel.
A fold-down faucet solves part of that problem by allowing the spout to move into a lower, more compact position when the sink is not being used. This can be especially helpful in small travel trailers, camper vans, boat galleys, and other mobile kitchens.
The Dometic 3313070-001 Fold-Down RV Galley Faucet is listed with a chrome finish, single control handle, fold-down spout, and 12-inch hot and cold hoses. It is designed as a compact galley faucet for compatible RV and marine installations.
Before ordering, verify the mounting hole, water connections, counter thickness, hose routing, and available clearance. A faucet can be visually similar to the original and still require modifications if the connection layout is different.

Why a Fold-Down Faucet Works Well in an RV
A fold-down spout provides a practical advantage in a compact galley. When the faucet is not needed, the spout can be lowered to reduce interference with nearby surfaces.
This design may help when:
-
The sink has a cover
-
Counter space is limited
-
The faucet is near a window or cabinet
-
The kitchen must be secured before travel
-
The galley is installed in a narrow aisle
-
The RV uses a compact one-piece sink and faucet area
The fold-down function should be tested before final installation. Make sure the spout moves smoothly and does not strike the sink, wall, window, lid, backsplash, or nearby appliance.
Single-Handle Water Control
The single lever controls hot and cold water through one handle. This allows the user to adjust water temperature and flow without operating two separate valves.
A single-control faucet can be convenient in an RV because:
-
It requires less counter space
-
It is easier to operate with one hand
-
It simplifies temperature adjustment
-
It reduces the number of exposed controls
-
It suits compact kitchen layouts
A single-handle faucet still depends on the RV’s hot-water system, pump, water heater, and mixing conditions. If water temperature fluctuates, the problem may be in the water heater or plumbing system rather than the faucet.
The 12V RV water systems guide explains how the pump, tank, water heater, faucet, and city-water connection work together.
Check Fitment Before Ordering
The most important fitment measurements include:
-
Existing mounting-hole diameter
-
Counter or sink thickness
-
Faucet base footprint
-
Distance to the backsplash
-
Spout height
-
Spout reach
-
Fold-down clearance
-
Hot-water hose length
-
Cold-water hose length
-
Supply-line connection type
-
Access beneath the sink
Remove the old faucet only after confirming that the new faucet can be installed through the existing opening.
If the old faucet uses different supply connections, you may need approved adapters or replacement lines. Do not force mismatched threads together. Cross-threading can damage the valve, supply line, or fitting and create a difficult-to-find leak.
What the 12-Inch Hoses Offer
The included 12-inch hot and cold hoses can simplify installation when the water connections are located close beneath the sink.
A short hose length can help by:
-
Reducing excess tubing under the counter
-
Keeping the plumbing area more organized
-
Minimizing large loops
-
Making the cabinet easier to use
-
Reducing the chance of hose contact with moving parts
However, 12 inches may not be long enough for every RV. Measure from the faucet connection to the hot- and cold-water supply lines before installation.
The hoses should not be stretched, sharply bent, twisted, or placed under constant tension. If the connections are farther away, use compatible replacement supply lines rather than pulling the included hoses into position.
Step-by-Step Faucet Replacement
1. Turn off all water sources
Turn off the RV water pump and disconnect city water. If the RV is connected to a pressure regulator or campground supply, close the supply valve.
Open the faucet briefly to relieve pressure in the lines.
2. Turn off and cool the water heater
If the hot-water line will be disconnected, turn off the water heater and allow it to cool. Never remove a pressurized hot-water connection.
3. Protect the cabinet
Place a towel or shallow container below the sink. Water may remain inside the supply lines even after the pump is switched off.
Remove stored items so you can see the fittings clearly.
4. Disconnect the old hoses
Loosen the hot and cold connections carefully. Keep track of which line connects to each side.
If a fitting is stuck, avoid applying excessive force to the faucet body or RV plumbing. Hold the stationary fitting while loosening the connection.
5. Remove the old faucet
Remove the mounting hardware from below the sink or counter. Lift the faucet out and clean the mounting surface.
Inspect the opening for old sealant, corrosion, cracks, or damage.
6. Position the new faucet
Place the Dometic faucet into the mounting opening. Confirm that the handle faces the desired direction and that the spout folds down without hitting surrounding surfaces.
7. Connect the hoses
Connect the hot and cold hoses to the correct water lines. Use the supplied sealing washers or the connection components specified by the product instructions.
Do not apply thread tape to a connection that seals with a washer unless the manufacturer specifically instructs you to do so.
8. Tighten the mounting hardware
Secure the faucet from below. Tighten it firmly enough to prevent movement, but do not over-tighten and damage the sink, counter, or faucet base.
9. Restore water pressure gradually
Turn on the pump or city-water supply slowly. Inspect every connection under the sink.
Run cold and hot water separately, then operate the handle through its normal range.
10. Test the fold-down movement
Move the spout through its full range. Make sure it folds down smoothly and does not contact the sink, cover, wall, window, or cabinet.
Leak Testing After Installation
A new faucet should be tested in more than one operating condition.
Check for leaks:
-
With the pump running
-
With the faucet closed
-
With the cold side open
-
With the hot side open
-
While moving the handle
-
While folding the spout
-
After the pump cycles off
-
After several minutes of pressurization
Look for moisture around:
-
Faucet base
-
Hot-water hose
-
Cold-water hose
-
Supply-line fittings
-
Sink opening
-
Cabinet floor
-
Water pump area
A slow drip may not appear immediately. Dry the connections, pressurize the system, and inspect again after several minutes.
Using the Faucet With a 12V Water Pump
When the RV is using its fresh-water tank, the 12V water pump supplies pressure to the faucet. The pump normally starts when the faucet opens and stops when the system reaches its pressure setting.
If the faucet has weak flow, check:
-
Fresh-water tank level
-
Pump inlet screen
-
Water filter
-
Kinked supply lines
-
Partially closed valves
-
Clogged aerator
-
Low battery voltage
-
Pump pressure setting
The RV water pump buying guide explains how flow rate, pressure, fittings, and pump selection affect faucet performance.
When connected to city water, the faucet may receive pressure directly from the external supply. Use a suitable pressure regulator if required by the RV manufacturer or plumbing system.
Why the Fold-Down Position Matters During Travel
The faucet should be placed in its travel position before the RV moves. A raised or extended spout may strike a cover, cabinet, window, or other object during vibration.
Before departure:
-
Fold the spout down
-
Close the faucet handle
-
Turn off the water pump
-
Disconnect city water
-
Check for water in the cabinet
-
Secure nearby sink covers
-
Make sure the handle cannot be bumped
-
Confirm that hoses are not pinched
Do not use the faucet as a handle or support point when entering, exiting, or moving around the RV kitchen.
Winter Storage and Freeze Protection
Water trapped in a faucet or supply hose can freeze and damage internal components. Before freezing weather, follow the RV manufacturer’s winterization procedure.
A general preparation may include:
-
Turn off the water supply.
-
Drain the fresh-water tank.
-
Open faucets and low-point drains.
-
Drain the hot-water system after it has cooled.
-
Bypass the water heater if required.
-
Remove standing water from the faucet and hoses.
-
Use approved RV antifreeze only when permitted by the system instructions.
-
Leave the faucet in a position that allows remaining water to drain.
The off-road camper winterization guide provides additional information about protecting RV plumbing, tanks, faucets, and water lines in cold weather.
Cleaning the Chrome Finish
Chrome surfaces can be damaged by abrasive cleaners, harsh chemicals, and rough scrubbing.
For routine cleaning:
-
Use a soft cloth
-
Use mild soap and clean water
-
Rinse away cleaning residue
-
Dry the faucet after cleaning
-
Wipe mineral deposits gently
-
Avoid abrasive pads and powders
-
Do not use strong chemicals unless approved
Clean the faucet aerator if water flow becomes uneven. Mineral buildup at the outlet can reduce flow even when the pump and supply lines are working correctly.
Common Problems and Solutions
The faucet leaks at the base
Check the mounting seal, mounting hardware, sink surface, and faucet alignment. A damaged seal or uneven installation surface may need attention.
A hose connection leaks
Inspect the washer, thread alignment, and fitting condition. Do not simply tighten repeatedly, especially if the connection uses a sealing washer.
The faucet has weak flow
Check the pump, filter, tank level, aerator, hose routing, and water pressure. A restricted line can affect the faucet even when the faucet itself is new.
The spout will not fold smoothly
Check for contact with the sink, backsplash, window, cover, or nearby hardware. Do not force the spout through an obstructed range of motion.
The water temperature is inconsistent
Inspect the water heater, mixing system, pump pressure, and hot-water supply. If only this faucet has the problem, check its hoses and internal cartridge.
