1. Low Water Pressure

Low water pressure is a common problem in Dubai. It often happens in older buildings or places with an unreliable supply.

Causes:

• Mineral buildup inside pipes due to hard water

• Leakage within the plumbing system

• Faulty pressure regulator

• Blocked aerators on taps and showers

How to Fix It:

1. Clean the aerator Unscrew the tap aerator and clean out mineral deposits. This alone often restores proper flow.

2. Check for leaks Look for damp spots, mold patches, or wet walls indicating a hidden leak. If leakage is suspected, calling a licensed plumber is the safest option.

3. Descale the plumbing system Dubai’s hard water leads to scale buildup. Professional descaling helps restore water pressure.

4. Replace old pipes In older homes, corroded or clogged pipes may need replacing for long-term results.

2. Clogged Drains

Blocked sinks, showers, and floor drains are extremely common due to the accumulation of hair, grease, food particles, or soap scum.

Causes:

• Hair buildup in shower drains

• Food waste and grease in kitchen sinks

• Sand and debris, especially in villas

• Poor installation or misaligned pipes

How to Fix It:

1. Use boiling water Pour boiling water into the drain to break down grease and soap.

2. Apply a drain cleaner Enzyme-based cleaners are safer and effective. Avoid excessive use of harsh chemicals.

3. Use a plunger or drain snake A plunger works for minor blockages; a drain snake can remove deeper clogs.

4. Call a professional If the clog is persistent, the pipe may be blocked further down and will need expert cleaning.

3. Running Toilets

A running toilet wastes water and increases your DEWA bill significantly—sometimes hundreds of dirhams per month.

Causes:

• Faulty flapper

• Broken fill valve

• Loose or worn-out flush handle

• Mineral deposits affecting toilet components

How to Fix It:

1. Replace the flapper This is a cheap and simple fix that stops most running toilet issues.

2. Check the float height Adjust the float to regulate water levels inside the tank.

3. Replace the fill valve If the toilet does not stop running even after adjustment, the fill valve is likely defective.

4. Professional servicing If the issue keeps returning, you may need a complete toilet mechanism replacement.

4. Water Heater Problems

Dubai residents often face issues like no hot water, inconsistent temperature, or unusual noises from the heater.

Causes:

• Sediment buildup

• Faulty thermostat

• Heating element failure

• Poor water pressure

• Old or corroded tank

How to Fix It:

1. Reset the water heater Sometimes a simple reset restores functionality.

2. Flush the tank Professional flushing removes sediment that affects heating efficiency.

3. Replace thermostat or heating element Faulty components are easily replaceable by a plumber.

4. Upgrade old heaters If your heater is more than 7–10 years old, replacement is often more cost-effective.

5. Pipe Leaks

Hidden leaks are one of the most damaging plumbing problems in Dubai. They can lead to mold, structural issues, and large water bills.

Causes:

• High water pressure

• Corroded or cracked pipes

• Construction vibrations

• Poor-quality installation

• Hard water leading to scaling and cracks

How to Fix It:

1. Identify and repair visible leaks Tightening loose connections or replacing worn-out washers may solve minor leaks.

2. Use sealing tape Temporary fixes like plumber’s tape can help until professional help arrives.

3. Call a plumber for hidden leaks Professional leak detection tools (thermal imaging, pressure testing) are required.

4. Replace damaged pipes If pipe corrosion is severe, replacement is the only long-term solution.

6. Dripping Faucets

A dripping faucet may seem minor, but it can waste hundreds of liters of water per month.

Causes:

• Worn-out washers

• Damaged O-rings

• Corroded valve seats

• Loose parts

How to Fix It:

1. Replace the washer or cartridge Modern faucets often require cartridge replacement rather than washers.

2. Tighten loose components Use proper tools to avoid damaging the fixture.

3. Replace the faucet If corrosion is severe or the design outdated, replacement is better than repair.

7. Sewer Line Problems

Sewer line blockages create foul smells and can cause wastewater to back up into your home—a serious hygiene hazard.

Causes:

• Tree root intrusion (common in villas)

• Grease accumulation

• Old or damaged sewer pipes

• Foreign objects flushed into toilets

How to Fix It:

1. Use sewer-safe cleaners Mild sewer cleaners may help with minor blockages.

2. Hydrojetting Professionals use high-pressure water jets to clear major blockages.

3. Camera inspection A CCTV camera inspection identifies the exact cause and location of the blockage.

4. Pipe repair or relining Broken sewer pipes require professional repair or relining.

8. Hard Water Damage

Dubai’s hard water causes scale buildup on fixtures, heaters, faucets, and pipes.

Effects:

• Reduced water pressure

• Limescale on taps and showerheads

• Reduced lifespan of appliances

• Blocked pipes

Solutions:

1. Install a water softener The most effective long-term solution for villas and large apartments.

2. Use descaling agents regularly Helps prevent thick limescale buildup.

3. Replace badly scaled fixtures Sometimes cleaning is not enough.
