Why does my bidet system add two water lines? I’m trying to exchange the one I inherited for a new one.

Faucet removal question

Complete novice here. My kitchen faucet broke and, this being the first time I've had such a situation, I decided to buy a replacement myself and see if I was up to the task of an installation. After disconnecting the lines and hose from the old faucet, the time came to remove the gasket on the old faucet and this plastic sheath made its presence known. For the life of me, I cannot figure out how to remove it. It seems completely stuck in place. Any advice about what it is and how I could be removed would be greatly appreciated.

What is this white hard puddy?

Whats the technical name of this.

I need to replace this but I can't find it online. Its attached to a spigot on a green roof.

What is this, and how do I get it to work normally?

Need to water our lawn. Just bought the house recently, and this faucet just trickles when I turn it. Why is it doing that? How can I get it to function normally?

How can I take this shit off? I tried everything for two days

Can I repair this myself?

Ran over this sewage pipe connector outside of our rented home. The landlord has Covid and is generally very difficult to deal with. Curious if I could replace it myself. If it’s possible to fix this on my own without too much trouble, how might I go about that?

Need help to find this part
