Blocked Drain or Toilet Choke — Causes, Fixes & Cost in KL
Water drains slowly, backs up, smells bad, or toilet water rises after flushing.
Estimated professional fix: RM150–RM500+ depending on blockage severity
A blocked drain or toilet choke is one of the most common plumbing calls in KL and Selangor homes, and it usually builds up slowly — hair, soap scum, and grease narrow the pipe until one day the water stops draining. What makes it urgent is when the blockage is in the main drain or the toilet: waste water has nowhere to go and can back up into the lowest floor of the house.
Common causes
Professional solutions
Safe DIY checks first
- 1Stop using the affected sink, shower, or toilet immediately — each flush pushes the blockage deeper
- 2Check whether other drains are slow too — that points to the main line, not one fixture
- 3Use a plunger with a full seal around the drain mouth; do not mix it with chemicals
- 4Watch for water rising in floor traps or a smell of sewage, which signals a main drain issue
When to call a pro

Simple fixture clearing with a manual or spring tool starts around RM150. Toilet removal, floor-trap cleaning, or a main-drain obstruction can reach RM500 and above. We confirm the blockage depth and method before starting, and workmanship is covered by the standard warranty.

Can I use chemical drain cleaner?
Avoid strong chemicals for severe clogs because they can damage pipes and make technician work unsafe.
How long does drain clearing take?
Simple clogs may take under an hour; deeper blockages need more tools and time.
Why does my toilet keep clogging?
Recurring toilet choke can be caused by trapped objects, weak flush, or deeper drain-line restrictions.
Is there a warranty after clearing?
Workmanship warranty applies to the clearing work, but new foreign objects or grease buildup are separate causes.
