I plan to hook the WM outlet hose out a cat flap in the window next to
it & connect some length of hose on to that & drape it on the lawn. The
WM pump should get the water out onto the lawn ok. Problem is the WM
outlet hose is quite a bit bigger than garden hose. I don't want to pay
much money for any hosing if possible (purpose made pipe will be likely
about $100). Unless I can get my hands on 20 odd lengths of the WM
outlet hose & find a simple way of joining them I think I may be stuck
with a smaller diameter hose (like garden hose) & some mechanism to have
to narrow the diameter down. If you have any bright ideas to my dilemma
please fell free to share them.

If you have any old plastic barrells around (20l+?, preferrably
biggerr), discharge the WM outlet into that to act as a surge tank.

Sounds like you could just position that outside the window, Either on
the ground with a feed pipe with funnel on top, or on a shelf that wm
outlet pipe can empty into.
