Kitchen Plumbing Issues? Here’s How to Diagnose the Problem First

Let's start by identifying the symptoms, which may give you a better indication of what is happening in your kitchen. Ask yourself these questions:

  1. Are you seeing slow drainage in the sink drain?

  2. Do you hear strange noises in your kitchen? Where are those noises coming from?

  3. Do you notice any leaks, and if so, where?

  4. When did the issue start, and is it getting worse?

This information will help make the proper diagnosis. Some issues are surface-level and easy to fix. Others point to more serious plumbing trouble. Let’s walk through the most common kitchen plumbing problems homeowners in Arizona face!

1. Leaky Kitchen Faucets

Potential Cause:

That constant drip isn’t just annoying—it drives up your water bill. Leaks usually happen due to worn-out washers, corroded valve seats, or loose parts.

What To Do:

  1. You can check for external leaks by feeling around the base of the faucet or under the sink. When fixing leaks, be sure to use plumber's tape on threaded connections to ensure a tight, leak-free seal.

  2. Internal leaks often require replacement parts or a complete replacement of the faucet. If you need to replace the faucet, proper faucet installation is crucial to prevent future leaks and ensure consistent water flow.

If tightening the faucet doesn’t stop the drip, it’s time to bring in a professional.

2. Slow or Clogged Drains

Potential Cause:

If your sink takes forever to drain, the culprit is usually grease, soap, or food buildup in the pipes. Overusing your garbage disposal or rinsing food scraps down the sink makes things worse.

What To Do:

  1. Avoid using chemical drain cleaners—they can damage your pipes.

  2. Try plunging. Fill the sink with enough water to cover the plunger cup, and ensure a tight seal between the plunger and the sink surface for effective suction. This helps ensure the water drains properly after the clog is cleared.

  3. Try a drain snake, or consider removing and cleaning the drain pipe to clear stubborn blockages.

  4. For a homemade solution, pour half a cup of baking soda followed by half a cup of vinegar down the drain.

If these DIY solutions don't work, Parker & Sons offers professional drain cleaning services that safely and effectively clear out buildup.

3. Low Water Pressure at the Sink

Potential Cause:

If the water pressure suddenly drops, check your faucet’s aerator for debris. That’s a quick fix you can handle.

What To Do:

  1. If pressure is low throughout your kitchen or home, it could signal a more significant issue, such as a partially closed shut-off valve, a supply line leak, a problem with your main water supply line, or corrosion inside your pipes.

  2. Improper installation of fixtures can also sometimes lead to pressure problems. In that case, it’s best to call in an expert.

4. Garbage Disposal Not Working or Leaking

Potential Cause:

A garbage disposal may stop working or start leaking due to a jammed blade, a tripped reset button, a failed internal seal, or improper installation.
What To Do:

  1. When your disposal won’t turn on or is making grinding noises, first check the reset button under the unit.

  2. If that doesn’t work, avoid sticking your hand inside. Safety first!

  3. Leaks from the bottom of the unit often indicate that the internal seal has failed, and the unit requires replacement. Proper installation is crucial when replacing a garbage disposal to prevent leaks and malfunctions.

This is a job best left to professionals. Our technicians can repair or replace your garbage disposal quickly and safely.

5. Under-Sink Pipe Leaks

Potential Cause:

Leaks under the sink are often due to loose slip joints, loose connections, cracked pipes, or a worn-out drain trap. You might notice water pooling, musty smells, or even mold.

What To Do:

  1. Inspect the area under the sink for visible signs of water, such as pooling water, dampness, or mold growth.

  2. Check all slip joints, connections, and the drain trap for looseness or corrosion, and gently tighten any loose fittings using plumber's tape if needed.

  3. Place a dry paper towel or cloth under the pipes and observe it over time to identify any slow leaks or drips. If a leak is confirmed or suspected, consider calling a professional plumber for repair.

These issues can worsen over time and lead to bigger problems. Catching them early means leaks can often be quickly fixed, making repairs easier and less expensive.

6. Dishwasher Backups or Leaks

Potential Cause:

If water pools at the bottom of your dishwasher or spills onto the floor, the problem could be a clogged drain hose, a faulty air gap, or a blocked filter.

What To Do:

  1. Check and clear the dishwasher drain hose to ensure it is not clogged or kinked, which can cause backups or leaks.

  2. Inspect the connection between the dishwasher and the kitchen plumbing to make sure all fittings are secure and free of leaks.

  3. If the problem persists, call a professional plumber to diagnose and fix any underlying drainage or leak issues safely and effectively.

7. Smelly Kitchen Drains

Potential Cause:

Foul odors coming from your sink usually mean there’s buildup inside the drain or the P-trap has dried out, leading to foul odors in your kitchen.

What to Do:

  1. Try flushing it with a mix of baking soda and vinegar, followed by hot water.

  2. If the foul odors return quickly, it could be a sewer gas issue or a venting problem that needs professional attention.

Frequently Asked Questions

How often does kitchen plumbing need maintenance?

Most kitchen plumbing requires minimal maintenance. We recommend checking for leaks seasonally and professional drain cleaning annually. In Arizona homes, where hard water is common, you should clean faucet aerators every 3-4 months to prevent mineral deposits from restricting water flow.

Can you help with financing options for major repairs?

Yes! We offer several financing options and payment plans for larger kitchen plumbing projects, making essential repairs more affordable. Our following financing options provide flexible terms that enable you to address critical plumbing issues promptly, protecting your home from water damage while respecting your budget.

Do you provide ongoing maintenance services?

Absolutely! We offer maintenance packages to keep your kitchen plumbing functioning optimally and prevent costly emergency repairs. Regular maintenance helps extend the life of your plumbing fixtures, prevents clogs in your kitchen drain, and ensures that your garbage disposal and dishwasher continue to work correctly.

How do I know if I need to replace my kitchen faucet or repair it?

If your faucet leaks despite replacing washers and O-rings, or if it’s more than 8-10 years old, replacement is often more cost-effective than continued repairs. Upgrading to a new faucet can also improve water efficiency and kitchen functionality with modern features.

Can you install a water filtration system as part of kitchen plumbing service?

Yes, we can install under-sink or whole-house filtration systems to address Arizona’s complex water issues. These systems protect your plumbing fixtures from mineral buildup and improve the taste and quality of water for cooking and drinking.
