Hey all, so I am at a loss here! Firstly, I should advise I am new home owner that wanted to learn some plumbing "on the job" and figured this would be an ideal DIY job. For the most part, it has gone pretty well. However...I have some leaks that seemingly no matter what I do will not stop leaking! Sometimes I manage to get to ALMOST stop as in , one drip every hour or so... but never fully stop. As you can see from the picture, I have done the following starting from the bottom: 1) The cold inlet wrapped in PTFE wape clockwise. (Initially I put maybe 6 complete wraps but had to up this when the leaking first appeared which slowed it down but not solved) 2) The white/grey junction (I forgot their name) is then screwed onto the cold inlet of the Water Heater. 3) Wrapped PTFE tape (quite a fair bit like in item 1 above) 4) Screwed down a 1/2inch > 15mm copper pressure fit connector (sorry not sure of the official name) and wrapped PTFE tape around the threads of this too. 5) Screwed the pressure fitting over the PTFE tape. Through various attempts to dismantle, remove and reapply PTFE tape and so and so on... I have found various scenarios occur... I can sometimes get the top Pressure fitting (item 4-5) to not leak but then the inlet (item 1) will leak slowly. I am not thinking maybe I need something else instead of PTFE tape? I haven't tried or used Jointing Compound but I have read this is very good too. Looking for any advice at this stage, greatly appreciated thanks guys!
