Best Water Pump Specs for Camper Sink

For a camper sink, the ideal water pump specifications balance adequate pressure for effective use and efficient water flow to conserve resources. Here's a concise recommendation:

**Pressure (PSI):**
- **40–55 PSI**: This range provides sufficient pressure for a strong stream without risking damage to the plumbing. Most RV pumps operate in this range to mimic household pressure.

**Flow Rate (LPM):**
- **5–8 LPM** (1.3–2.1 GPM): Adequate for washing dishes while conserving water. However, many standard RV pumps are rated higher (e.g., 11–15 LPM or 3–4 GPM) to accommodate multiple fixtures (showers, toilets). For a sink-only setup, a lower flow rate is acceptable, but standard pumps are often designed for broader use.

**Key Considerations:**
1. **Energy Efficiency**: Opt for a 12V DC diaphragm pump (quieter and more efficient).
2. **Self-Priming**: Ensures reliable water pickup from the tank.
3. **Duty Cycle**: Look for pumps rated for intermittent use (10–15 minutes continuous operation).
4. **Noise Level**: Diaphragm pumps are quieter than piston pumps.
5. **Adjustability**: Faucet flow restrictors can reduce actual usage, even if the pump has a higher capacity.

**Example Pumps:**

- **Singflo HY-304551R: 55 PSI, 11.36 LPM (3 GPM) or 7.6LPM (2GPM) 12v

— common in RVs, versatile for sinks or larger systems.

- **Lower-Capacity Options

**: For sinks only, consider pumps around 5–8 LPM, though they may be less common.

**Final Recommendation:**

Choose a **40–55 PSI pump with ~5–8 LPM** for a sink-focused setup, but consider standard RV pumps (11–15 LPM) if future expansion (e.g., adding a shower) is possible. Ensure compatibility with your camper’s plumbing and electrical system.
