Who Pays - Burst Pipes

[Jeff Lubeski]

We had a cold spell last week. I get a text Sunday night from a tenant that the radiator pipe is broken (4 days after the cold spell ended). What I know is that she ran the propane tank empty and did not get it refilled until Saturday (I do not know what day it ran out). It is a clearly negligence on her part that created the problem and this is the second time she ran the tank empty. Because I wanted it all checked out and fixed properly, I called the repair person in and paid. I think she should be responsible. My contract does not spell out that costs from negligence are the tenants responsibility. How would you approach this situation?
