Same can be said about the water heather and the dishwasher. If they both failed so close one another it was either an Act-of-God (and outlier that no one ought to experience more than once, statistically speaking) or more likely the result of malign neglect. If the GP had just bought the house, he/she ought to have made a better job at surveying the infrastructure and considering repair cost in the total price. If that's the case, it reflects poorly on them to have been taken by surprise by those events.
