When the water in your kitchen sink swirls into the drain, it is entering the sink basket strainer. Sink basket strainers collect food and particles from the sink water. When the basket is filling with refuse, it can be cleaned from the side. Basket striners are usually found in commercial and or industrial applications.
The metal rim surrounding the sink drain is the top of the piece, and the sides of the "basket" gradually come together below the sink narrowing into a metal tube which interfaces with the sink tail piece. Over time, a basket strainer will wear out and this is first noticed as a leak under the sink. When the piece corrodes and begins to leak, it needs to be replaced.
Magic plumbing.com is located in San Francisco, and is not your typcial urban plumbing service company. In their sink repair Magic Plumbing San Francisco video, which can be found at http://www.youtube.com/watch?v=DB1b-b2 xiLk, you can watch one of their service men replacing a basket strainer underneath a kitchen sink in a restaurant. The basket strainer, as the video demonstrates, is that metal piece which fits into the drain opening of your sink and which conencts, on the under side of the sink, to the sink the tail piece.
Why do basket strainers wear out? Basically there's time, and there's the occasional bumps plus there's the flow of hot and cold water. Hot water, as you may recall expands metal, and cold water contracts it. The alternating contraction and expansion of the part, over the years, can lead to a corroded and or leaky basket strainer.
The first thing you might notice, when your basket strainer corrodes, is leaky water under the sink. However, a leaky basket strainer is only one of the plumbing problems that can cause water leakage under the sink. To test if the problem is a leaky basket strainer fill your sink with water, and then gently touch a piece of tissue to the rim of the basket, where it appears under the sink. If the tissue fills up with water that tells you the basket strainer is leaking, and needs to be replaced.
Next you can either call a plumber or try to do the repair job yourself. If you decide to make the repair, you will need to purchase a new strainer basket and tail piece. The tail piece is a short straight metal piece that connects the bottom of the basket strainer to the copper plumbing of the house. The copper pipes won't need to be replaced, in this replacement job.
Next you will need to remove the old basket strainer. The most important thing to keep in mind is lesson number one that plumbers learn in plumbing school "Righty Tighty Lefty Loosy."
Once the strainer basket and tail piece are removed you want to put the new custom fitted tail piece into the top of the copper piping under the sink. Next, fit the strainer basket into the drain hole of the sink, from above. The lips of the basket will keep it from falling into the drain hole, however, before actually inserting the basket, you will want to add a ring of plumbers putty around the underside of the lips of the strainer basket to make a nice seal and prevent leaking.
The rest of the installation takes place under the sink. Tighten the nuts and washers that connect the copper piping tail piece and basket strainer. Don't over tighten anything as that may cause cracking. When everything is in place, turn on the water and check for leaks.
