To be honest, until recently I was extremely disappointed in our plumbers. I called service to my house three times to re-plan our communications. But so far none of them have answered me. I don’t know what the difficulty of this task was for them, but I already thought that you can forget about the repair. But I got lucky with the last one. I accidentally found out about POM Group Plumbing
https://pomplumbing.ca/mixing-valves...ce-and-repair/. To date, they have all the drawings for my object ready and we have a ready action plan. So, if necessary, only contact them. This is my friendly advice.
