<p>A self-priming siphon has an inverted U-shaped tube filled with a hydrophilic material where one end of the tube is connected to a smaller diameter tube such that when the other end of the tube is immersed in a liquid, capillary action causes the fluid to rise in the tube above the level of the water and thereafter fall through said one tube end causing a suction which primes the siphon.</p> |
