I’ve had to undertake a lot of practical research into the phenomenon of blocked drains, lately…we are talking toilets here actually, I’m afraid. I’ve been astonished by how poorly a sink plunger performed, even when combined with gallons of chemical unblocker. There is no way to form the required seal, so I resorted to a different tactic.
Ideally, I’d use a high-pressure hose, but if the drain isn’t clear within about 10 seconds, the entire house fills with effluent: -nasty. Turbulent vortices, created by a flapping motion under the water surface, are the answer, I’ve discovered. These can be made energetic enough to erode and dislodge the most stubborn of blockages.
Today’s invention is an attempt to achieve the intense flapping required without having to use your hand. Instead, a variant on this trash picker device is suggested, with a flipper in place of the ‘beak’ and the whole thing encased in some kind of ezy-clene rubber sleeve. I still haven’t thought up a way to make this flexible enough to go around a U bend, but fortunately, water is sufficiently incompressible for pressure waves to be transmitted over longish distances -making this usually unnecessary.
