A useful battery powered pump for emptying cisterns etc

I came across this useful little pump the other day. Works using re-chargeable AA batteries It's very handy for those hard-to-get-at places. You can use it to empty or fill without any spillage !!

I got it from http://www.dohead.com/   Phone me if you have difficulty getting it.

So far I've found several uses for it. Saved me a pile of time the other day when I needed to empty a header tank that was really close to the roof.
