Quick Answer
Yes, foot-pump sinks can be installed in new tiny house builds, offering a low-maintenance, self-contained water storage and handling solution that reduces plumbing complexity and reliance on municipal water.
Design Considerations for Foot-Pump Sinks in Tiny Houses
When integrating a foot-pump sink into a new tiny house design, consider the following key factors to ensure a seamless installation:
- Water Storage Capacity: Aim for a minimum 10-gallon (38-liter) water tank to provide adequate water supply for basic hygiene needs. A larger tank (20-30 gallons or 75-114 liters) will offer better comfort levels and flexibility.
- Foot-Pump Efficiency: Choose a high-quality foot pump with a flow rate of at least 1.5 gallons per minute (GPM) to minimize pumping effort and maximize water pressure. This is particularly essential for larger water tanks or longer pipes.
Installation Best Practices
Proper installation of the foot-pump sink is crucial to prevent leaks, contamination, and other issues. Follow these best practices:
- Pipe Routing: Use food-grade, UV-resistant PEX tubing to route water from the tank to the sink, taking care to minimize bends and kinks that can restrict flow or harbor bacteria.
- Installation Height: Position the water tank at a comfortable pumping height (around 36 inches or 91 cm) to reduce pumping effort and prevent strain on the pump and user.
- Drainage: Ensure proper drainage from the sink by installing a suitable trap (e.g., P-trap or S-trap) to prevent sewer gases and odors from entering the tiny house.
