Zebra RV RV Combo Water Pump and Faucet R3700 - Polar White, Compact All-in-One with Travel Lock

The Zebra RV R3700 Polar White Combo is a compact pump-and-faucet unit that switches between tank and city water modes with a single ergonomic handle and travel lock.

This all-in-one Zebra Combo City Water Pump and Faucet is designed for confined spaces in RVs, boats and camper vans where a reliable water source and easy mode switching matter. Finished in polar white, the R3700 combines a hand-operated pump action for tank use and a simple handle movement to open a city water feed, so you don’t need separate valves or a bulky installation. Its travel-lock feature prevents accidental tank drainage while on the move, and the unit ships packaged and ready to fit most mobile living setups.

How do I switch between tank water and city water?

Changing water sources is done with the single lever on the faucet: upright short strokes activate the internal pump to draw from your onboard tank, while a downward motion gradually opens the city water valve. For quick taps keep the handle slightly down; press fully down and it locks for continuous city-supplied flow.

• Tank mode: handle upright, pump with short strokes to build pressure.
• City mode: move handle down slowly to open the city water valve.
• Quick use: hold handle partially down for intermittent flow.
• Continuous flow: press handle fully down until it clicks into the locked position.

What installation or maintenance should I expect?

The Zebra R3700 is made for straightforward installation in compact counters or sink cutouts common to RVs and boats. Routine maintenance is minimal—inspect seals and connections for leaks and rinse internal lines as part of seasonal care to avoid buildup.

• Fits standard small sink openings in mobile kitchens and heads.
• Check O-rings and hose clamps at initial install and annually.
• Flush lines when switching long-term between tank and city sources.
• Keep the travel-lock engaged during transit to prevent tank loss.

Does the travel lock protect my water tank while driving?

Yes—the handle includes a lock position specifically to prevent the pump from being accidentally left in tank mode during travel. Engaging the travel lock secures the handle so it can’t be depressed, guarding against unwanted pumping or open flow that could drain your supply.

• Mechanical lock secures handle for transit safety.
• Prevents accidental activation of pump while on the move.
• Simple push-down motion releases lock for normal use.

How does the R3700 fit into compact galley or head layouts?

The compact footprint and integrated pump-faucet design free up counter and cabinet space by removing the need for a separate external pump or city-water mixing valves. Its polar white finish offers a clean look that blends with most RV and boat interiors.

• Combined pump and faucet reduces installed components and plumbing complexity.
• Polar white finish matches many mobile interiors for a discreet appearance.
• Packaged for simple retrofit or new installations in small spaces.

Who is this for: The Zebra RV R3700 Polar White Combo is ideal for RV owners, boaters and camper van builders who need a reliable, space-saving faucet that handles both tank and city water without additional valves. It suits DIY installers and pros fitting compact galleys or wet baths who want straightforward operation, a travel lock for peace of mind, and a neat polar white aesthetic.
