Dear [your landlord’s name],
I am a tenant at [your address] and I am writing to let you know about [a leak/a problem with the water pipes] in [the bathroom/the toilet/the kitchen/the living room/the hall/ the bedroom/another location within your flat/the shared corridor/ the block/another flat number].
{There is a slow leak which is depositing water [in/on] [location]}
{While the pipe is not yet leaking, it is clear that it is on the verge of failing, with potentially disastrous consequences.}
{This pipe has been incorrectly installed and it is clear that it will cause leaks in the near future}
{Not only [is this causing/could this cause] damage to the [property/furnishings/carpeting/flooring/paintwork], but it is also a health hazard.}
{In the first instance I would be grateful if you could arrange for repairs, but I would also like to explore claiming for the damage to my [furnishing/possessions] on the insurance, which I believe must be done through yourselves as landlord}.
I would be grateful if you could get in touch to arrange a visit at your earliest convenience, so that I can show you the issue in person.
You can contact me on [phone number] or via this email address. I look forward to receiving your reply as a matter of urgency, but by [date, two weeks in the future] at the latest.
Yours sincerely,
[Sign your name]
