What Does Mold Around Faucets Mean?

While it is hard to find mold growth inside water pipes and filters, mold around the kitchen and bathroom faucet is a common occurrence. When you fill up a cup of water, you want it to be clean, odorless and tasteless.

Unfortunately, it is possible for mold to get into your drinking water, and seeing strings or small pieces of black substances can come as an unpleasant surprise. The small black pieces are mold strings and can start forming in your faucet. This article focuses on the implications of mold growth on faucets, how to recognize signs of mold growth and how to eliminate them. If the growth persists, you need to call professional plumbers to remove and replace the faucet.

Mold growth

Mold requires water, oxygen and food to survive. If these elements are not complete, their growth will be inhibited. Mold is usually spread through airborne spores. These spores are transferable, land and develop on any material that offers them the required components for survival. Water lines typically do not have the oxygen and organic food molds need to thrive, which makes their occurrence there rare. Yet, some circumstances may encourage mold to thrive in your drinking water.

How can my water get mold?

If your water source is a well, then you might be at risk of getting mold in your water faucet if the way cap is not properly sealed or damaged. There is also a chance of mold survival even if your water supply is from the town or city. If your system has high amounts of oxygen and organic food material (could be anything as harmless as a paper filter cartridge), mold can thrive in the water.

Additionally, you should know that mold can contaminate your water delivery pipes, water softeners, water well, water storage tanks and any other form of water distribution system.

Getting rid of mold growth

Eliminate leaks

The first step in eliminating mold growth from your kitchen or bathroom faucet is to get rid of any leaks. Molds require a constant supply of water to survive, and removing drips help to stop mold growth. You may need to check the seal around the base of the faucet. If the fixture is leaking, you may need to tighten it. If the drip remains persistent, the faucet may have rusted and needs a replacement.


Another way to eliminate mold growth around the faucet is by using bleach to clean the faucet. You can do this by diluting a 10 percent bleach solution and using a clean washcloth to scrub the head, stem and handles of the faucet once daily. The bleach harms the mold and its spores. Ensure you allow water to run continuously from the faucet for one minute after washing the faucet head to clean out the bleach.

Replace the aerator

If the mold is present in the aerator only, extract and clean it with a bleach solution. If the aerator has rusted or is in a bad state, buy a new one. If you do not know how to change the aerator, your plumber can help you.
