I get it now, maeve...

Actually, if you could just send 220 volts down the 3 wires (red and black hot and white ground) to the pump it would pump water to where yer old connection was that went to the house... A 220V rated switch or "disconnect box" with lever would do fine as a shut off... Nuthin' would get hurt by doing this and you really aren't violating any codes that I know of... Might of fact it would probably make you pump happy to run now and then...

Of course there wouldn't be a pressure tank but it doesn't matter since all you are doing is kinda using the pump direct... Very basic but virtually free water...
