Pressure at P same as the pressure at Q
Siphon cannot function if there is a leak between P and Q
Pressure in the rubber tube at R must be equal to the pressure at P to ensure the continuous flowing of water
Siphon is not functioning if end of rubber tube, R is at higher level than the surface of the water in the aquarium
