I've just moved into my first property and I'm clueless when it comes to plumbing, I'm tight on cash right now so I'm looking for some advice please. I'm looking for general advice on what I will possibly need to connect a trap to my sink. I have no idea what the white modified connection is and if I can use a 40mm tee to connect to it. From what I can see I need a tee but the connection to the tee and the trap wont be possible without some other pipe/connector? And I'm unsure if I can connect a tee to the white connection. Thanks for your time.
