Is that Odor Coming From the Faucet Water or the Drain?
Having clean water to drink is a priority and you need to make sure you have a proper working whole house water filtration system in your home. Sometimes people smell odors in the kitchen from the sink and most people think it is the water and not the sink drain, however it is generally the drain and not the running water.
Are you catching a whiff of a stinky unpleasant smell in one of your sinks? Are you wondering if it’s coming from your drain or your sink water? After letting water run for a bit, pour water into a glass and take it outside to smell and drink it. If there’s no smell then its the drains.
Most drains can be cleaned without harsh chemicals. Smelly drains are often the result of buildup from hair, soap, grease, food, and other debris. The classic way to handle this problem is with vinegar or lemon juice.

“For a more effective and equally simple way to clean the drain, use dishwashing liquid and hot water. Choose a dishwashing liquid designed to break up grease, such as Dawn, Ivory or Palmolive. Bring a pan or kettle of water to a boil, then turn off the heat.
Pour 2 or 3 tablespoons of dishwashing liquid into the drain, then slowly pour in the hot water. Wait 15 minutes, then prepare another pan of boiling hot water. Pour the water down the drain to flush away the loosened debris.
A smelly bathroom sink drain is a common problem, as odor, residue and bacteria accumulate regularly in the drain. Luckily, keeping the drain clean and odor-free is a fairly easy task, and requires only a couple of inexpensive household ingredients. Avoid expensive and chemically-based drain cleaners sold at supermarkets and home improvement stores; they are often ineffective and use chemicals that you do not want around your home or family.”
