Turning off your stopcock will prevent flooding, but water can still be hiding in every pipe and inside the boiler, which when frozen, can cause huge amounts of damage. A drain down protects by removing water from the pipes and preparing any systems which contain or use water (such as boilers, showers, toilets etc). By booking your drain down with Haven, you will not need to worry about damage like this ruining your holiday home and taking the fun out of ownership.
