If you own a holiday home in France, you might not be aware that you have to turn the water off at the main when you leave.
In case of any water damage, you wouldn't be covered by your insurance company.
Some insurance companies advise you to turn the water off if you leave your house 3 or 4 days even if it is your main residence. Double-check your contract or contact your insurance company. Each company is different.
I've had to deal with several claims due to water damage for my clients and it is never good news when the repairs cost about €10,000 and the insurance company only covers 50%....
If you have a holiday home in France, do remember to drain the pipes in the winter before your departure.
