The simple solution is to bung the vent and feed pipes in the attic, or
wherever (see elsewhere for details) and cut the pipe, catching the 1/2 pint
or so that flows out into a container. An automatic pipe cutter will cut a
pipe within an inch of a parallel wall, and is less that a tenner. You then
might need a straight coupler to repair the cut pipe - less than 75p.

It's still a good trick. I've used an injector pump to do the same
thing. (Or whatever they're called: one of those things that attaches
to a mains water outlet and sucks when you turn on the water. Jet of
water entrains the air, and "pulls" it out). Found in waterbed stores,
nonelectric, cheap, fine dirt and sludge don't bother it.

It'll also pull a lot more head than a wet-n-dry, so beware crushing
something.
