7 Common Kitchen Plumbing Issues and How to Fix Them  

Clogged Sink Drains

When food particles, grease, soap residue, and other things accumulate in the pipes, they restrict the flow of water. With time, this leads to complete blockages and calls out for the worst nightmare of people, standing water in the sink with all the germs and bacteria from the pipe.  

Here’s how to fix it:

Use a plunger to create suction and dislodge the clog. Once the water is clear, add a good amount of baking soda to the drain and let it settle. After 5 minutes, add vinegar and let it react and clear out all the dirt and grease that it stuck in the pipe. After leaving it in for 10 minutes, pour boiling water to clear it out.  

Leaky Faucets

Leaky faucets may seem to be a small issue, but they can give a very high rise on your water bills and damage your items if left unsupervised. This usually happens when some components inside the faucet are worn out; it can include a washer, valve seat, or even corrosion due to the minerals depositing from the hard water.

Here’s how to fix it:

Turn off your water supply and take the faucet out. Once you open it, there are three things you need to check:

  • Inside the faucet handle, you will see a round ring-like thing. If it seems loose, replace it. 
  • Clean or replace the valve seat if it’s corroded.
  • If the faucet is old, consider replacing it with a new, water-efficient model.

If the leaks are persistent, you can always call for a professional plumber in Cibolo, Schertz, New Braunfels, San Antonio or any other surrounding areas.

Low Water Pressure

Weak water flow from your kitchen faucet can make washing dishes and cooking difficult. This issue is often caused by blockages in the aerator, water-line problems, or pressure issues in the main water supply. 

Here’s how to fix it:

  • Clean the aerator: Unscrew it from the faucet, soak it in vinegar, and scrub off any deposits.
  • Check the shut-off valves: check if they are fully opening to allow maximum water flow.
  • Inspect for leaks: Look for signs of leaks under the sink or in the main water line leading to your kitchen.

Garbage Disposal Problems

If your garbage disposer is not turning on and keeps making grinding noises. This could be due to a jammed blade because of fibrous food or bones, electrical issues, or clogged disposal from improper waste disposal.

Here’s how to fix it:

  • Press the reset button on the bottom of the disposal unit.
  • Use an Allen wrench to rotate the blades and remove jams.
  • Avoid disposing of fibrous foods like celery, potato peels, or coffee grounds in the disposal.
  • Flush with ice-cold water after every use to clear debris.

Leaky Pipes Under the Sink

Due to a loose connection between the pipe and joint, faulty fitting, or corrosion, your pipe tends to leak underneath the sink. These leaks can lead to a very unhygienic kitchen as they attract bugs, grow mold, and even cause water damage to the other parts of the kitchen.

Here’s how to fix it:

  • Apply plumber’s tape to minor leaks in pipe joints.
  • Replace damaged pipes or fittings if corrosion is present.
  • Check the P-trap (curved pipe under the sink) for blockages that may cause leaks.

Dishwasher Drainage Issues

If your dishwasher doesn’t drain properly, it can leave standing water inside the appliance, leading to bad odors and poor cleaning performance. It may be due to a clogged drain, a blocked airgap, or a failing drain pump.

Here’s how to fix it:

  • Inspect the dishwasher filter and clean out food particles.
  • Check the drain hose for clogs and clear any obstructions.
  • Ensure the air gap is clear to prevent backflow issues.

Water Heater Issues Affecting Kitchen Plumbing

If your kitchen sink isn’t supplying hot water, there could be some issue with your water heater. In an electric water heater, the inner elements could have malfunctioned, hard water sediments could build up in the tank, or a faulty thermostat could give you inconsistent water temperatures. 

Here’s how to fix it:

  • Flush the water heater tank regularly to remove sediments.
  • Check the thermostat settings and adjust them if necessary.
  • If your heating element is defective, replace it.
