Shurflo 105-013 RV 12V On-Demand Potable Water Supply Pump – 1.0 GPM

This compact automatic demand fresh water pump offers durability and dependability making it ideal for low volume, intermittent duty applications. The SLV pump self-primes up to 2.5 vertical feet while delivering 1.0 GPM at open flow. The 12 volt low power consumption motor, equipped with thermal protection and a long life pressure switch rated to 30 PSI, provides high pump performance and reliability.

• On-Demand: Turns on when pressure decreases
• Single-Fixture: Designed to handle plumbing systems with one fixture
• 3-Chamber Diaphragm: Three independent pump chambers for a smooth, even flow
• Small Camper System: Mounts between the water tank and the distribution piping for single fixture cold water systems

An on-demand pump moves water through the fresh water system. It should be installed between the water storage tank and the distribution piping system. The pump turns itself on by an internal switch that activates when the water system pressure decreases. The internal pressure switch shuts the pump off when pressure is reestablished. Opening a faucet will reduce the internal water system pressure, and this turns on the pump.
