Clogged Kitchen or Bathroom Drain — Causes, Fixes & Cost in KL
Water drains slowly, sits in the sink or shower tray, or backs up when you run multiple taps.
Estimated professional fix: RM 150–RM 700+ depending on clog severity
A slow or clogged drain in a Malaysian kitchen or bathroom is almost always one of three things building up over months: grease in the kitchen P-trap and the horizontal run, hair in the bathroom traps, or — the one that surprises people — a foreign object (wet wipe, sanitary product, a lost bottle cap) that has worked its way into the toilet line. The tell is the pattern. A kitchen drain that slows after every fry points at grease. A bathroom drain that slows in weeks points at hair. A sudden total blockage with gurgling from another drain points at an object or a main-line problem. The fix depends on the cause: mechanical clearing first, enzyme treatment to keep it clean, and high-pressure jetting only where the line is badly crusted.
Common causes
Professional solutions
Safe DIY checks first
- 1Note which fixtures are slow: one sink points local, several at once points to the shared line
- 2Run water into the slowest fixture and watch another drain — bubbling or rising water elsewhere marks the main line
- 3Check the P-trap under the sink for visible grease film or a partial blockage you can reach
- 4Smell: a sewage note (not just stale water) points below the trap, toward the main line
When to call a pro
What affects the cost
Manual snaking or rodding of a single fixture starts around RM150–RM250. Where the kitchen line is badly crusted with grease, high-pressure water jetting of the full run runs RM350–RM700. A camera inspection is added where the blockage keeps returning, so the actual obstruction is seen and priced correctly. We clear the line mechanically first — strong caustic chemicals damage older PVC joints and make follow-up work unsafe — and the work carries the standard warranty.

Are chemical drain openers safe for my pipes?
Strong caustic chemicals can damage older PVC joints and are unsafe for enclosed spaces. We recommend mechanical clearing plus enzyme treatments — safer and longer-lasting.
How much to unblock a kitchen drain?
Manual snaking: RM 150 to RM 250. High-pressure jetting: RM 350 to RM 700 for a full kitchen line.
How can I prevent future kitchen clogs?
Never pour cooking grease down the sink; use a mesh strainer; and run hot water + a monthly enzyme treatment to keep the line clean.
