one was cutting holes in the back of the new kitchen cupboards to get
the Miele hoses with their damned big non-return valves through.

I thought they were volume limiting rather than just
non-return valves, which gives more excuse for the size.


Nearly - they are an electric valve and the hose is a hose within a hose,
with a water leak sensor in the outer hose. So if the inner hose springs a
leak, the valve is shut off. I suspect, though I don't think it says
explicitly in the brochures, that is the machine detects it's full when it
shouldn't be, that the valve is is shut off too.
