Some Information about Plumbing and Plumbing tools
In plumbing, a sink is a bowl-shaped fixture, usually made of porcelain (or, especially in the kitchen, stainless steel), that is used for washing hands or small objects such as dishes, nylons, socks or underwear. Old sinks were often made of enameled steel or cast iron. In American plumbing parlance, a bathroom sink is known as a lavatory. Sinks generally have faucets, usually cold and hot, and a drain. When a sink becomes stopped-up or clogged, a person will often resort to use of chemical drain cleaner or a plunger.

plunge your drains before they stop up.

overflow. If you have a small type spring brush, use to clean
