I'm not sure if image desciptrion is correct: As for me it looks like one 65mm hose (one on the left) is supplying water to three 38 hoses and one other 65mm hose. There are also two 65-38 mm converters.
Look at the second 65mm hose (the one connected using converter) - It looks like it isn't pressuised. Mibars (talk) 15:38, 23 October 2011 (UTC)
