The hot water went out in our rental 3 days ago, and the landlord has been out to fix it the last two days. While it does last for a few hours, it goes back out. I have texted him about it and never get a response, he just shows up does whatever to fix it and leaves without informing us what the problem is, or respond at all by call or text or knock on the door to let us know what's going on. The water heater is in the adjoining unit below us, so we cannot access it on our own. What steps should we be taking to document this if needed? What are our legal rights as far as getting it fixed for good? Thank you in advance!
