Single-Lever Faucet Issues
 

My landlord recently installed a new single-level faucet in our kitchen (ball-type, I think). We have two problems:

1. It is very loose where the bottom of the spout sleeve meets the faucet base. We are worried that will pull the whole lever out with the tubes. How do I tighten it?

2. We added a Brita filter to the tap and now we have to play with it to get it to turn off completely. Any suggestions?

Thanks.

call the landlord and have them fix this.
You pay for it in your rent.

No need to do DIY work when you pay for a working liveable dwelling in my opinion.

Ditto. You rent.
