Within the last decade, do-it-yourself home improvement projects have become more and more popular, as people have realized they do not always need professionals to complete a job for them. One area where this is especially true is with plumbing installation of drains in your home, particularly with sinks.
Most sinks in your home can be found in either your bathroom or your kitchen, thus you will most likely be installing sink drains in one of these two areas. If you are doing drain plumbing installation in the kitchen you will use a 1-1/2″ drain, while in a bathroom you will most likely use 1-1/4″. Usually the drain will be made from PVC plastic, but some older drains are brass and chrome.
