When you move to a smaller place outside Bangkok like Pattaya or Phuket you need to prepare yourself for the worst in another way then if you live in Bangkok.
When the water is up to your knees or there is no shower for a day you are already to late you need to act before it happen.
You need the number to some one how can fix water pumps because with out the pump no water.
You need an electrician to fix the electric system if it would fail.
You need some to collect the drain tank under your house because if it gets full you do not want to live in the house.
You need the number to the truck that delivers water if the water supply should fail in the area.
The number to the closest living police officer and doctor would be a good idea if you live far out otherwise the local number to the hospital and police station would do.
It could be a good idea to have the fire department number as well but the chance that they would come when your house is on fire if you not give them money is very slim and if you live far out just forget about it.
Try to meet all of this people before something happen, ask them to fix something small and if they really suck ask for a new one. When you deep in trouble they will use that to raise the price.
If you have any other ideas please let me know and I will post it here
