Common Causes of Clogged Drains

1. Grease and Oil Buildup

Pouring grease or cooking oil down the drain can lead to serious clogs over time. As grease cools, it solidifies and sticks to the walls of your pipes, restricting water flow.

2. Hair Accumulation

Hair is a leading cause of clogs in bathroom drains. Call for after hours plumbing services in Neuse Township, NC. It binds with soap scum and other debris, forming tough blockages that are hard to remove without tools

3. Soap Residue

Traditional soaps contain fats that can combine with minerals in water to create soap scum. This scum builds up on the inside of pipes, reducing their diameter and leading to clogs.

4. Food Waste

Kitchen sinks often get clogged due to food scraps that should have been disposed of in the trash or compost. Coffee grounds, eggshells, and fibrous vegetables are common offenders.

5. Foreign Objects

Small objects like toys, jewelry, or other items accidentally dropped into drains can cause blockages. Toilets often get clogged when non-flushable items like wipes or sanitary products are flushed.

6. Tree Roots

In outdoor plumbing, tree roots can infiltrate sewer lines through tiny cracks, causing blockages as they grow and spread.

7. Mineral Buildup

Hard water can leave mineral deposits in your pipes, gradually narrowing them and increasing the risk of clogs. (Get more information)

How to Address Clogged Drains

1. Use a Plunger



A plunger is often effective for clearing minor clogs in sinks, bathtubs, or toilets.

2. Remove Debris Manually

For visible clogs caused by hair or food, use a drain snake or your hands (with gloves) to remove the blockage.

3. Try Baking Soda and Vinegar

Pour a mixture of baking soda and vinegar down the drain, followed by hot water. Learn more about emergency plumbing in Neuse Township. This natural remedy can break down minor buildups
