This really is exceptional but can happen with household appliances if for example they are all purchased at the same time. Ten to fifteen years down the road they all wear out.
This year I've replaced the multi locking mechanism on the plastic back door and replaced several double glazed panels that were misting.
Renewed the garage alarm.
Replaced the synchronous motor on the CH motorised mid position valve.
Replace the washers on the two water tanks in the loft.
Yesterday I replaced the kitchen sink waste pipe. It's south facing and had disintegrated with sunlight.
What I consider a fairly quiet year for household breakdowns so far, but if I had to pay someone to do them, the cost would mount up.
