I have no space for plumbed-in d/washer and no cash for redesigned kitchen so interested in table top models. Can these be attached to the taps using a T-junction (so water can still be drawn from tap for kettle etc, with waste hose hooked into sink (like the old spin dryers did) rather than integral fit with permanent plumbing? Maker sells as table top then when asked says has to be permanently set in under work top! Trade descriptions?! Anyone know of REAL table top? Not bought one yet
