Hi Community,
I have recently brought a property, unfortunately we discovered a leakage under my outdoor tap connected to mains water meter. I dug out the mud under the tap and found there is a water leak near the coupling (not sure what they are called). Can someone help me fix this issue? I'm good with my own hands if I know the right technique and tools. I'm really not sure what they are called and how to fix them? Could you please guide me the fix and what are the tools needed? Uploaded pictures for your reference. Please have a look. Cheers.
