I need a 12v self-priming pump. Is there a good one that anyone can recommend? I need it to be able to self-prime and suck water out of the top of a 5 gallon water container. How many PSI and GPM would be enough? How much would be overkill?

Thanks for the tip. I just ordered it.

All these sort of diaphragm pumps make enough noise to wake Ned Devine! I have that one, it’s good. Primes itself.

That's why I changed to a hand pump. they work well and make no noise....also self priming, just a hose to the water tank and it's installed! No electricity, no wiring.

PS. Who's Ned Devine? And what he doing sleeping in your van?

Don’t any of you know a good movie when you see one? Waking Ned Devine http://www.rogerebert.com/reviews/waking-ned-devine-1998
Rent

Or better- buy it you can even show it to the kids (I think)

Ned who?
How long does your pump run to have to have a hand one?

At 2 am, I get up to get a glass of water. The pump runs for 10 seconds...about 9 seconds longer than it takes to wake my wife up! The hand pump makes no noise, and doesn't vibrate half the van insides in the process.

Even when the pump runs during the day, it just makes too much noise.....others' results may vary!

In my kitchen cabinet redesign, I can use electric pumped, hand pumped, or bottled water...for most trips, bottled water wins.

Use an accumulator

Many of the people here sound like they don't have an accumulator (air bottle) in the system. My conversion didn't have one, so that when the water was turned on, the pump would start sending a steady string of "E"s at 10 WPM. (bz bz bz bz bz for non-Morse folks). I added an accumulator to the line after the pump, and now I can fill a cup of water without the pump needing to kick in. When it does run, it runs for a longer time to refill the accumulator.

The accumulator is on the pressure side of the pump acting like the pressurized water tank on a home well water system. It stores a small amount of water with air above it to soften the surges of the pump and to store a bit of water under pressure. It is not strictly necessary but might be nice.
