Hello, I am no good at DIY but came here for help on a plumbing problem. I have a small leak as per picture attached, I think the shading machine tap needs replacing but I am not sure. Have checked the copper piping that appears fine, but the drip appears to be coming from the machine tap. The y plastic tap above appears to be fine. To repair the issue is this something easy to do myself plus the part wise? O I tried my best to seal the leak but it is not working hence the tape on the pic.
