Today, we changed our kitchen sink. We drained the system, connected new taps,sink. Put water back on - first time ever no leaks. So off for a bath! We have no hot water.Having connected the cold valve on the washing machine to the valve on the hot water tap etc. we had a small amount of hot water only for it to dry up. We then went up into loft to find that the cold tank is not filling up. How do we get the water into the tank. The mains water is rnning lovely. I hope someone knows the answer, because we have no idea! And five babies wanting bathing! ::
