10 Common Kitchen Sink Problems and How to Fix Them

10 Common Kitchen Sink Problems

These are the issues we encounter most frequently. Some can be handled quickly; others require professional plumbing expertise.

1. The Sink Drains Slowly

Water goes down, but slowly, like it's in no hurry. Usually it's grease and food bits sticking to the inside of the pipe. Hot water and a bit of dish soap can help for a day or two. But if it keeps coming back, the pipe needs a proper clean, not a quick fix.

2. The Sink Is Fully Blocked

No drainage at all. Water just stays in the bowl. This is often a solid clog further down the line — vegetable peels, bones, or something that shouldn't have gone in there in the first place. A plunger sometimes works. If it doesn't, we bring in proper drain rods or a small camera to see exactly where the block is.

3. Leaking Pipe Under the Sink

You open the cabinet under your sink and the base is wet. Sometimes there's a small puddle. This is almost always a loose joint or a worn-out seal. Left alone, it damages the cabinet wood and can lead to mould. It's a quick job for us — usually under an hour.

4. Bad Smell From the Drain

That smell is not "normal kitchen smell." It's usually trapped food waste or a dry P-trap (the curved pipe under your sink that's supposed to hold a little water and block sewer gas). If you've been away and the kitchen wasn't used for a while, the trap can dry out. Running the tap for a minute usually fixes that. If the smell stays, there's buildup that needs clearing out.

5. Faucet Keeps Dripping

Drip. Drip. Drip. All night. Nine times out of ten, this is a worn washer or cartridge inside the tap. Not expensive, not complicated. But it wastes real water over weeks, and honestly, it drives everyone in the house a little mad.

6. Weak Water Pressure at the Tap

If the water barely trickles out, check the aerator first — that little mesh screen at the tip of the tap. Mineral deposits build up there over time, especially with UAE's harder water. If cleaning it doesn't help, the issue could be further back in the supply line, and that needs a plumber's eye.

7. Double Sink Not Draining Evenly

This one's specific to two-basin sinks. One side drains fine, the other backs up into it. A double sink uses a shared drain line, with pipes joining at a T-connection. Both basins feed into one trap before the main line. If that shared section is blocked, or the double sink plumbing wasn't installed at the right slope, both sides suffer. Not a DIY fix — getting the connections wrong here causes repeat problems.

8. Garbage Disposal Jammed or Noisy

A sudden loud grinding sound, or the unit just humming and not spinning — that's usually something stuck inside, like a fruit pit or bone. Never put your hand in. Switch it off at the power first. If it's jammed often, the blades may need replacing.

9. New Leak After a DIY Fix

We see this a lot, honestly. Someone tightens a pipe joint themselves, it seems fine for a week, then it leaks again — sometimes worse. Plumbing joints need the right seal and the right amount of tightness. Too loose or too tight, both cause problems. If your last fix didn't hold, that's usually why.

10. Old, Corroded Pipes

In older buildings, especially ones over 10-15 years old, the pipes themselves start to wear from the inside. You'll notice discoloured water, frequent small leaks, or a metallic smell. At this point, patch fixes stop working. The pipe section usually needs replacing.

Common Mistakes People Often Make

We've seen these patterns repeat enough times to know they cause problems. Avoiding them can save you money and frustration.

What Not to Do

• Pouring hot oil down the drain — It hardens and blocks the pipe. This is one of the most common causes of backups.
• Using strong chemical cleaners repeatedly — They wear out old pipes faster and can damage rubber seals.
• Ignoring a small leak because "it's just a few drops" — It adds up to real damage over a month, plus hidden mould growth.
• Fixing a double sink issue without checking both sides together — The problem is usually in the shared section, not in one individual line.

When to Call a Professional Plumber

Some issues are simple to fix yourself. Others aren't worth the risk. Know when to call before the problem gets worse.

Call a Plumber If

• Water keeps backing up even after clearing the clog
• There's a foul smell coming from the drain that won't go away
• You have a leak you can't locate or stop
• The garbage disposal won't turn on or makes odd noises
• You're renovating and need new pipes or fixtures
