Pressure had dropped on our combi boiler this morning, it often does, so wife repressurised, she thought as normal but within about 5 minutes boiler was making a loud noise and pressure needle going bananas. Phoned my boiler insurance and whle on the phone the boiler started to leak water from the casing. I have shut the mains supply but that means I only have cold water till my insurers arrive on Monday What is the likely damage to the boiler, any suggestions. Thanks
