You probably spend more time at your kitchen sink than you spend thinking about your kitchen sink. The kitchen sink is a hub of activity and a vital part of any household. It can also be a hub of unpleasant activity that can cause problems in your happy home. Today, we’re going to take a few minutes to look at your kitchen sink and how to care for it. Your kitchen sink is most likely mounted to a countertop. Most kitchen sinks are made from stainless steel, porcelain-coated cast iron, resins, acrylic, copper or some kind of stone (or stone composites) like quartz, granite, or marble. The durability of the material is important because sinks can be bacterial reservoirs. The less durable the material, the more often you’ll need to replace your sink to avoid problems that bacterial growth can cause.
Underneath your sink is the sink drain. A sink drain consists of the pipe that run from the drain hole that’s visible in the sink to the main drain in the house. Directly under the sink, you’ll also see a p-trap – a curved piece of pipe. The p-trap is an essential element of any drain. The p-trap retains a bit of water, which forms a seal. This seal prevents gases from further down the drain from escaping into the house. The plumbing code requires p-traps in drain lines. If your sink doesn’t have a p-trap, or your p-trap is damaged, you’re going to encounter some really unpleasant smells.
Many kitchen sinks also feature a garbage disposal. A dishwasher may also be integrated into the garbage disposal or sink drain. No one disputes the utility of either a garbage disposal or a dishwasher, but they can also be a source of problems for your kitchen sink and drain.
Kitchen sink do’s
Do clean your sink regularly. Cleaning the sink surface can help reduce bacteria and odors, remove food particles and prevent staining. If you stack dirty dishes in the sink, clean the sink after washing the dishes. Also clean the sink if unprepared foods – raw meat, eggs, etc., come into contact with it. Sanitize the surface with bleach to kill bacteria and remove stains.
Do use the right cleaning products on your sink. Follow the manufacturer’s guidelines for caring for your sink, based on the materials it’s made from. Surface scratches can eventually lead to a breakdown of the sink surface. This can promote rust and surface cracks, or encourage staining.
Do look for leaks. Your faucet can leak, sending a stream of clean water into the sink. Your drain can also leak. Unlike the faucet, the drain leaks dirty, potentially hazardous water. Drain leaks can be sneaky, so periodically check the drain for leaks. Signs include scale build-up, obvious water accumulations or water stains, and mold or mildew growth under the sink. Drains can leak if the sink mounting flange is not set well, or the plumber’s putty underneath it is deteriorating. Couplings around the drain stem and p-trap can also deteriorate or loosen. Periodically, check the drain couplings. Especially if you have a dishwasher or garbage disposal, make sure your drain couplings are tight. Vibrations from these machines can loosen the joints in your drains and cause leaks – or worse – a cruddy flood.
Do check the water shut-off valves periodically. Local shut-off valves are notoriously cheap. Check your valves periodically to make sure they can still shut off the water. If the valve shut-off spins continuously, replace it.
Do use cold water in the disposal. Hot water just allows grease to congeal farther down the drainpipe.
Kitchen sink don’ts
Don’t put grease down the drain.
Grease hardens when it cools and it makes a pretty effective stopper. Unfortunately, a grease plug usually doesn’t form in a convenient, easy-to-reach place. And unless you throw a bunch of grease down the drain at once, a grease plug forms slowly over time. To dispose of grease, pour it into a tin can and freeze or refrigerate it until it hardens. Then toss it out. You could also pour the grease into a plastic bottle or jar with a lid and trash it.
Choose what you dispose of carefully. If you have a garbage disposal, don’t put coffee grounds down the drain. Coffee grounds combine with other things in your drain (like grease), and turn into an impossibly hard substance. Also on the no-fly list: eggshells. Same problem; same result. In fact, avoid putting fats, oils, stringy vegetables, potato peels, pasta, rice, beans and non-food items down the disposal. Pasta, rice and beans all swell in water, so they take up a lot more room in the drain. If they collect in a place that’s normally wet, (even in their ground-up state), the diameter of your drain pipe will shrink.
Don’t use chemical drain cleaners in the kitchen sink. Chemical drain cleaners are really hard on your pipes. They’re also dangerous to you! To keep your drain clean and clear, you can put a cup of baking soda and a cup of vinegar down the drain. Let it sit for a few minutes and then wash it down the drain with hot water. You can also use an enzymatic drain cleaner to clear out the kitchen drain.
Don’t ignore drips and leaks. Even a small leak can do a lot of water damage. If you have a household plumbing problem you’d like us to take care of for you, contact us at (617) 362-0377
