The grease problem, explained
Hot cooking oil poured into a sink does not stay liquid. It cools quickly against the pipe wall (especially the cooler sections behind the cabinet) and forms a thin film. Each pour adds to that film. In our climate the film stays soft and sticky for longer, which means it catches every coffee ground, rice grain and noodle fragment that follows.
After about three months of normal cooking, that film has narrowed your kitchen drain noticeably. After a year, it has formed a hard rim that a chemical pour will not budge.
Three weekly habits that pay for themselves
- Wipe pans before washing. A used paper towel or kitchen tissue in the bin removes most of the residual oil before any of it reaches the sink. This single habit prevents more clogs than any product on the market.
- Run hot tap for 30 seconds after dishwashing. Hot water mobilises whatever soft grease is still in the trap and pushes it further down the line, where it has space to clear naturally.
- Pour a kettle of boiling water down the kitchen sink once a week. No chemicals needed. The thermal shock dislodges most fresh film before it hardens.
Hair in the bathroom — the simplest fix
A two-ringgit silicone hair catcher in the shower drain is the single best plumbing investment most KL households can make. We replace bottle traps full of hair every week that would never have clogged with a catcher in place.
What to keep out of the toilet (no matter what the packet says)
- Baby wipes labelled “flushable”. They are not, in any plumber’s definition.
- Sanitary products and cotton buds. They get caught at the first bend.
- Kitchen paper towel. Designed not to dissolve quickly — the opposite of what you want.
- Cooking grease, leftover paint, expired medicine. Each has a proper disposal route.
If you remember nothing else: only the three Ps belong in a toilet — pee, poo and (toilet) paper.
When a drain stays slow despite the right habits
If you are doing everything right and a particular drain still slows every couple of months, the cause is usually structural: a back-fall in the pipe, an old joint catching debris, or (more rarely) a root intrusion at the outflow. A short camera inspection settles it once. We’ll send you the recording so you can see it for yourself.
