### Instruction: Write a letter to my landlord, Dave, asking them to hire a plumber to repair a leaking faucet.
### Response: Hi Dave, I'm reaching out about our leaking sink faucet. The sink has been leaking for about a week now, and I've tried tightening the faucet and making sure that the faucet is fully closed, but it still seems to be leaking. It is a pretty constant drip, and is filling a cup up every hour. I think it probably needs to be seen by a plumber who can decide if it is fixable or needs to be replaced. Could you call a plumber and ask them to step by?
