Q. How do you install a waste coupling?

Answer

If you do not already have a waste coupling in the wall, you should have a plumber install one for you. Make several calls to plumbers in the region and explain to them where you would want to put the sink. You should collect price quotations from each plumber, and then pick the one whose services are within your financial means. Permit the plumber to install a new waste coupling on the main waste line in your house, which will run from the wall where you want the sink to the main waste line. In order to get rid of unclean water, your home is outfitted with a waste coupling that runs throughout the whole house and connects to subterranean sewage lines. Do not try to install a new waste line on your own since doing so might potentially expose you to raw sewage.
