The white plastic thing is an elbow ,the white tape at the bottom of it is PTFE . THERE IS NO WAY THAT THIS IS OK DON'T DO IT
I shall simply retire to a quiet corner of my shed and gently weep myself to sleep.. Find a happy place Find a happy place Find a happy place
Here’s another tip for non plumbers. Think about your own job, imagine me trying to do it. If you think it would end in disaster and failure, apply that same logic to my job.
There is an exception to this. If said DIYer had used the ptfe tape to wrap around his own elbow. Restricting blood flow, causing the limb to become infected and leading to generalised sepsis and eventual death, thus ending his bloodline and the chance of him having offspring to copy his diy techniques. Then obviously that’s a fair use of ptfe and an elbow.
