Last 4 day camping trip we only used 1 of 10 gallons of water because it was to difficult to pump and use for brushing teeth and washing hands. I was thinking of installing a 12V water pump for my sink (10 gallon reserve). I want low flow so I don't waste all my water in a few minutes. What do you think about this Bayite 12 V DC Pump? Note: I have more wires then shown in the "underside" sink picture. Edit: Do I need to change my faucet? I plan to add a switch somewhere.
