Leaking pipe connection.
This leak was quite obvious with water spraying out of the pipe fitting.
After Isolating the water supply. I removed and replaced the fitting. I also cut out a small section of the pipe, as the fitting cuts into the pipe to make the join. Generally if you try to remake the join the thread doesn’t sit in the right place and will leak again. Once the water was back, check the area for leaks, this includes connections that may have been disturbed further along the pipe work.
For any signs of a leak, give me a call. Meeting your plumbing needs.
