YoungTree 12V RV Fresh Water Pressure Pump 5.5 GPM 70 PSI — Diaphragm Self-Priming with 3/4" Garden Hose Adapters

YOUNGTREE's 12V diaphragm water pump delivers up to 5.5 GPM and 70 PSI of on-demand water pressure for RVs, boats, trailers and off-grid cabins.

If you need a compact, reliable DC pump that supplies steady household-style water from tanks or temporary sources, this model is built to run multiple fixtures, resist overheating and simplify installation. Designed as a direct-replacement style pump, it includes garden-hose fittings and sealing tape so you can get flowing quickly. The combination of automatic pressure switching and adjustable cut-in pressure gives practical control over performance without extra accessories.

How much water flow and pressure can I expect?

This pump provides a maximum flow of about 5.5 gallons per minute and a top pressure rating of 70 PSI, enough to support several low-demand fixtures simultaneously. Real-world output varies with inlet conditions and pipe layout, but it’s sized to serve showers, sinks and light irrigation from the same system.

• Peak flow: approximately 5.5 GPM for steady delivery
• Maximum pressure: 70 PSI for strong spray and consistent faucets
• Suitable for handling 3–4 typical faucets running at once
• Performance depends on tank head, hose diameter and fittings

Will it turn on and off automatically?

Yes — the pump includes an integrated pressure switch that starts the motor when a faucet opens and stops it when the line is closed, enabling hands-free, on-demand water. The cut-in pressure is adjustable so you can tailor how sensitive the switch is to flow requirements.

• Automatic on/off with built-in pressure switch
• Adjustable cut-in range from roughly 40 to 80 PSI
• Prevents continuous cycling by matching cut-in to system needs
• Ideal for conserving power in off-grid setups

How is the pump protected from damage or dry running?

The pump uses thermal protection to shut the motor down if temperatures climb too high, helping avoid heat-related failures. It is also designed to tolerate short periods without water, offering temporary dry-run protection until supply is restored, though extended dry operation should be avoided.

• Thermal cutout at about 158°F (70°C) for motor safety
• Short-term dry-run resilience reduces risk during brief outages
• Recommended fuse sizing (20–30 A) for circuit protection
• Follow good plumbing practice to prevent prolonged dry running

What comes in the box and is installation difficult?

The pump ships as a complete kit including 3/4-inch garden-hose adapters and Teflon tape so you can make leak-free connections from the start. Installation is straightforward for anyone comfortable with basic 12V wiring and threaded plumbing connections; mounting hardware and simple electrical protection are recommended for safe operation.

• Includes 3/4" garden hose adapters and Teflon tape
• Requires a 12V DC power source and recommended 20–30A fuse
• Direct-replacement form factor fits many same-type pumps
• Simple plumbing connections and mounting for DIY installs

Who this pump is for: Owners of RVs, campers, boats, trailers, tiny homes and off-grid cabins who need a compact, high-pressure 12V pump that balances strong flow with automatic on-demand control. It’s suited for those replacing a like-for-like pump or upgrading to achieve household-style pressure from a tank system, and for DIY installers who want a ready-to-fit kit plus dependable thermal and dry-run protection.
