Drip no drop

Something exciting is happening in our house. We have lived here for 9 years & never had a shower (we do bath so we're not smelly). Well we are having our bathroom done by builders, we will have a shower in the next couple of weeks. Mr KC has been doing 'things' too. He has fitted a water softener to stop the limescale from our hard water (you can see the scale on the tap). Today he's done something in the loft with the water tank. As a result we have no water, just a few drips. As you can see. He says it's air trapped. So no bath for the kiddies tonight....
