One of the thing you take for granted in a 'normal' house, is that, when you turn a tap, water comes out.
Up until now water consisted of lugging 20 litre containers, fulling them in town and filling kettles and pots when water was needed for cups of tea and cooking.
Now that we have the tanks, I bought a pressure pump (good old Ebay) and Jim installed it and this is what happens.
Turn the tap - water comes out. Turn the tap off - water stops coming out!
Another sad example of what some people find exciting!
