vokera sabre 29he boiler in morning red light on and pressure at o?

hi, the sabre has a low preassure cut off switch,if it keeps losing preassure then there is a leak somewhere, check the discharge pipe first, which should be a copper pipe,that will be outside ,same wall as flue terminal normally, but lower down,check for dripping, then go round and check all rads and valves, then its only pipework left, you can buy a leak sealer made by fernox, any good plumbing merchants will stock this. comes with instructions. good luck
