Yes, plumbing change is another repair. In Toronto, I really like the people who work with high rise building plumbing - they can definitely solve any of your questions in a short time so that you don't have any excuses for worry. I propose to pay attention to their list of services - as you can see, the range is quite wide, from banal household solutions to a whole complex repair or replacement of pipes. So you can be sure that you have already found the right option.
