Re: Water Butt Solar Pump

You may need more head than you think...
When the lower tank is nearly empty and the upper tank is nearly full, this
could add another 2+ metres of head alone...

Bilge pumps are very robust and pretty cheap off Ebay, but check the max.
head figures, are some of them can barely pump one metre...
