I’m officially a plumber

I am cheap, yes I own it. My sons house had a leak under both bathroom sinks and of course I am not calling a plumber. I took my pink girl tool kit and took it apart. Two trips to Lowe’s and it is fixed and working like new for a total of 12 dollars in parts. The other side is leaking from the connector at top so I need to find a tool to loosen as it is cranked down. YouTube will help me with this. Don’t be afraid to try do it yourself, the satisfaction of learning something new and it working is fantastic.
