you mean the pump will burn out if I try to force water through a

odd metres down the SAME diameter pipe?

Both. My understanding of WM pumps are that they are generally designed
to pump out the WM for a maximum head of about 1 metre, aka the height
of the generic laundry tub.


My wife may let me get away with a crap looking length of pipe but not
likely a big bin outside the window.

2nd hand laundry tub with a couple of water (or water loving) plants in
it in pots {:-).
