Pumping water in small quantities

I would start right here on CR4/Globalspec.

I'm not sure if they can lift that far or not, but fountain pumps (for decorative waterfalls) are about as cheap as you can get. If one can't do it, I'm sure two could (first one pumping into a container that supplies the second) and I suspect two fountain pumps will still be significantly cheaper than a single industrial pump.

You will also want either a sensor (float or weight-operated switch) or a timer to ensure the motor does not run for long periods with no water to pump.

Is freezing a concern in BA? I suspect it is only rarely a problem.

Hi:

No, very cold weather in winter here means not less than 5 ºC

" but fountain pumps (for decorative waterfalls)"

Hi: I´ll consider that pumps. Thanks a lot.

Collect the water in a 5gall tank the use a small submersible with an integral float switch, this will pump when there is liquid and shut down when there isn't.

Hi Gabriel,

Have you considered to use a commercially available condensate pump - also known as condensate lifting unit? It consists of a small container collecting the fluid, a level sensor and a small pump. For more information please refer to : http://www.wilo.com/cps/rde/xchg/en/layout.xsl/3525.htm

The easiest and cheapest solution would be to attach a hose or downspout (drain pipe) and run it down to a place where it won't discharge water across the path below such as a garden, somebodys flower pots, or an outdoor drain. If this is a possibility it's a lot better and ceaper than pumping it upward. If you must pump upward, I like the fountain pump idea - cheap and not a lot of power consumption. Use floats to turn them on and off.

Of course there is always the option of putting an awning over the path to catch the water so it drips down on the far side, keeping the path and passers by dry.
