Dear Ms. Landlady,
This letter is to follow up on our March 10th phone conversation about the water heater in the rental at 222 Study Lane, which is not working. This plumbing defect is causing us significant convenience, we need hot water to bathe and wash dishes. We are also concerned that the water leaking from it will damage your floor and we do not want to be held responsible for it, or for the increased water bill.

As of today, the water heater has not been repaired, and no one has contacted us with definite plans about when repairs will be made. We presume you understand that you are required by California law (Civil code 1941.1 – see attached) to keep all “pluming… maintained in good working order.”

We would appreciate hearing from you as soon as possible about this. You can contact me at my personal email address.

Sincerely, 
Terry Tenant
