Tenancy law: What to do in case of leakage and maintenance?

Questioner

Hello, I am renting a house from a private individual, I have been renting it since 1982. It is an old house with overdue maintenance. The landlord is of the opinion that given the low rent we are responsible for all maintenance ourselves. Now yesterday I discovered that a water pipe has burst under the floor, which means I will get a very high annual bill. I called a plumber and he says that a pipe has burst under the floor, which means my concrete floor has to be opened up. We reported this to the landlord immediately yesterday, he says I have nothing to do with it, just blame it on your insurance, I will not discuss this, the costs are for you. This is not possible and allowed, is it? What should I do, I can't go to the toilet, wash, shower, etc.

If the water pipe has burst due to overdue maintenance of the pipework at the landlord's expense, he is also obliged to compensate you for your damage.
