Blocked Drain in Multan: Causes, Fixes and When to Call

A sink that drains slowly on Monday is often a sink that will not drain at all by Friday. Most people try whatever is under the kitchen counter, pour it down, and hope. This guide to blocked drain Multan homeowners deal with every month explains what usually causes the blockage, what you can safely try yourself, and the signs that mean the problem is deeper than one sink.

The Short Answer

Find out whether one drain is slow or several. One slow drain is usually a local blockage you can clear with a plunger or by cleaning the trap under the sink. If several drains are slow, or water comes back up in another fixture, the blockage is in the main line and needs a plumber.

Common Causes of a Blocked Drain

• Grease and food in the kitchen sink. Cooking oil cools and sticks to the inside of the pipe, and food scraps collect on it.
• Hair and soap in the bathroom. Hair binds with soap scum and forms a plug in the trap or just below the drain.
• Wipes, tissue and other items in the toilet. Wet wipes do not break down the way toilet paper does, even when the pack says flushable.
• Small objects. Bottle caps, cloth pieces and children’s toys can lodge in the bend of a pipe.
• Scale and old pipes. Mineral deposits can narrow older pipes over time, which makes every other cause worse.
• Problems outside the house. A choked outside line or a poorly sloped pipe causes slow drains that keep coming back.

Signs to Look For

• Water drains slowly or stands in the sink or basin.
• A gurgling sound from the drain after water runs.
• A bad smell coming from the drain.
• Water backing up in a second fixture when you use another one, for example the floor drain bubbling when you flush.

Safe Steps You Can Try Yourself

1. Remove any visible debris and the strainer, and clean them.
2. Run very hot tap water for a minute to loosen grease. Avoid pouring boiling water into plastic pipes or into a cracked basin.
3. Use a plunger with a good seal over the drain. Block the overflow hole with a damp cloth, and plunge firmly in a steady rhythm.
4. Place a bucket under the sink, unscrew the trap, and clean out what has collected. Wear gloves and refit it tightly.
5. Run water again to check the flow, and look for leaks around the trap.

A mix of baking soda followed by vinegar can freshen a drain and loosen light residue, but it will not clear a solid blockage.

What Not to Do

• Do not pour strong chemical drain cleaners into a drain and then plunge, because the liquid can splash back onto your skin and eyes.
• Do not mix different cleaning products. Some combinations give off harmful fumes.
• Do not push a stiff wire or a sharp object hard into the pipe, which can scratch or puncture it.
• Do not keep repeating chemical cleaners on the same blockage. If it does not clear after one try, the cause is elsewhere.

When to Call a Plumber

• More than one drain is slow, or water appears in another fixture.
• The blockage comes back within days of clearing it.
• There is a sewage smell, or water leaks around the pipe or trap.
• The plunger and trap cleaning have not worked.
• The drain is outside the house or under the floor.

Keeping Drains Clear

• Fit a strainer in every sink, basin and shower drain, and empty it daily.
• Wipe greasy pans with tissue before washing, and put the tissue in the bin.
• Flush only toilet paper. Wipes, cotton and cloth go in the bin.
• Run hot water down the kitchen drain after washing up.
