Kitvance 110V Fresh Water Pump 6 GPM 70 PSI — Self‑Priming Diaphragm with Pressure Switch

Kitvance 110V AC Fresh Water Pump is a self-priming diaphragm pump delivering up to 6 GPM at a 70 PSI cut-off with an integrated pressure switch and brass fittings for steady household and outdoor water pressure.

This compact electric water pump is engineered to raise and maintain water pressure for taps, showers, RVs, garden hoses and small irrigation systems. Designed for straightforward installation, it includes a pressure-controlled automatic start/stop system, corrosion-resistant brass connectors and a built-in strainer. The pump is rated for 110V AC power and is optimized for continuous home use with noise-reducing bearings and a four-chamber diaphragm layout.

How much water pressure and flow can I expect?

The pump provides a maximum flow of 6 gallons per minute and a factory-set cut-off pressure of 70 PSI. Typical cut-in pressure ranges from 25–40 PSI depending on application (home or large RV), and bypass protection activates around 85–90 PSI.

• Maximum flow: 6 GPM
• Cut-off pressure: 70 PSI
• Cut-in pressure: 25–30 PSI (home) / 30–40 PSI (large RV)
• Bypass safety: 85–90 PSI

How does the automatic pressure switch simplify use?

The built-in pressure switch monitors system pressure and automatically starts or stops the pump as needed, removing the need for manual control. This ensures consistent pressure at fixtures and prevents the pump from running dry when demand stops.

• Automatic start/stop based on pressure thresholds
• Reduces manual intervention for daily use
• Protects against continuous running when no flow is present
• Suitable for faucets, showers, and hose-fed systems

Will it be loud or require special mounting?

Noise has been reduced through NSK double ball bearings and a one-piece four-chamber diaphragm design, producing quieter operation than many comparable pumps. Standard mounting on a solid, level surface with anti-vibration pads will further reduce transmitted sound.

• Low-noise NSK double ball bearings
• One-piece four-chamber diaphragm for smooth flow
• Mount on a stable surface, use vibration isolation if needed
• Suitable for indoor and sheltered outdoor installations

What fittings and installation details should I know?

The pump uses a 1/2" NPT threaded inlet/outlet (approx. 20.95 mm) and ships with two 1/2" barbed hose adaptors plus two brass fittings for quick connection to hoses or pipework. It self-primes vertically up to 10 ft and horizontally up to 155 ft under recommended conditions.

• Thread size: 1/2" NPT (Φ 0.82" / 20.95 mm)
• Included: 2x 1/2" barbed hose adaptors, 2x brass fittings
• Self-priming: up to 10 ft vertical, 155 ft horizontal
• Recommended fuse: 25–30 amps for safe operation

Who this pump is for: If you need reliable pressurization for a household tap, small RV system, garden hose station, car-wash hose, or low-volume irrigation, this Kitvance 110V diaphragm pump is built for those uses. It suits homeowners and RV owners who want automatic pressure control, quieter operation, and easy plumbing hookups without industrial complexity. The unit is backed by a 3-year factory warranty and technical support for straightforward troubleshooting and long-term service.
