## Why a yearly check pays off

Most plumbing problems start small. A cistern that runs a little. A floor trap that drains a bit slower. A stain on the ceiling that only shows after rain. Caught early, these are cheap and quick to fix. Left alone, they become ceiling repairs, hacked walls and arguments with the neighbour below. This checklist from our 

home plumbing guide for Kuala Lumpur

[/ →](/)

 gives you a simple yearly routine, with separate lists for landed houses and condo units. Start with the meter test in our 

High Water Bill guide

[/guide/high-water-bill-meter-leak-check/ →](/guide/high-water-bill-meter-leak-check/)

, because it tells you quickly whether anything is leaking out of sight.

Set a date once a year, and add a short gutter and floor trap check before the heaviest rain.

## The checks every home needs

### 1\. Meter leak test

Close every tap and appliance, note the meter reading, and read it again after a few hours with nothing used. Any movement points to a leak after the meter. Our 

Water Meter Leak Test Calculator

[/tools/meter-leak-test-calculator/ →](/tools/meter-leak-test-calculator/)

 turns your two readings into litres per day.

### 2\. Taps and mixers

Look for drips at the spout and around the base. Open and close each tap. One that needs force to shut off usually has a worn washer or cartridge.

### 3\. Under sinks and basins

Open the cabinets with a torch. Feel the flexible hoses and the waste trap for damp. Look for swollen boards or stains, which show an old slow leak.

### 4\. Toilets

Listen for a cistern that keeps hissing or trickling after it has refilled. Check the floor around the base for damp. A few drops of food colouring in the cistern will show if it is leaking into the bowl.

### 5\. Floor traps and drains

Pour water into floor traps in rooms you rarely use, so the water seal does not dry out and let smells in. Lift the covers and clear hair and debris. Note any drain that is slower than it should be.

### 6\. Water heater

Check that it heats, that the breaker does not trip, and that there are no drips at the pipe joints or casing. Look for rust stains below a storage heater.

## Extra checks for landed houses

-   **Roof tank.** If you can reach it safely, look for rust, cracks, damp below the tank and a lid that fits. Look at the water for sediment or algae.
-   **Overflow pipe.** An overflow that drips all the time means the float valve is not shutting fully.
-   **Booster pump.** Listen for unusual noise, and notice if it starts when no tap is open. That points to a leak or a failing part.
-   **Exposed pipes.** Check outdoor pipes and the area around the meter for rust, damp ground or green growth.
-   **Gutters and downpipes.** Clear leaves and silt before heavy rain. Make sure downpipes empty into a drain that can carry the water.

-   **Outdoor drains.** Clear silt and leaves from the drain around the house so rainwater can get away.

## The shorter list for condo units

In a condo, building management looks after the shared tanks, pumps, risers and roof. Your yearly list covers the inside of your unit:

-   Meter test on your unit meter (ask management where it is if you are not sure)
-   Taps, mixers, bidet sprays and the hoses under sinks
-   Toilets, including the base and the cistern
-   Floor traps in every bathroom, balcony and service yard
-   Water heater checks
-   Bathroom and balcony floors: look for cracked grout or tiles that sound hollow, which can let water through to the unit below

If you find damp in your ceiling, tell building management. It may be coming from the unit above.

## A simple timing plan

You do not need to do everything on one day. Before you start, make sure everyone at home knows 

how to turn off your main water supply

[/guide/how-to-turn-off-main-water-supply/ →](/guide/how-to-turn-off-main-water-supply/)

. Many owners split the checks like this:

| When | Landed house | Condo unit |
| --- | --- | --- |
| Once a year | Meter test, tank, pump, heater, exposed pipes | Meter test, heater, bathroom floors |
| Before heavy rain | Gutters, downpipes, outdoor drains, roof stains | Balcony drain, window seals, ceiling stains |
| Every few weeks | Top up floor traps in unused rooms | Top up floor traps in unused rooms |
| After a water cut | Brown water, toilet refill, pump prime | Brown water, toilet refill |
| Between tenants | Full list plus photo record | Full list plus photo record |

## What a yearly check will not find

A visual check catches most early signs, but not all of them. It will not show you the condition of pipes buried in walls and floors, and it will not tell you how much life an old heater or tank has left. If your house is older and still has galvanised iron pipes, look out for brown water, weak flow at every tap and leaks that keep coming back. Those are signs to read the 

Pipe Replacement section

[/pipe-replacement/ →](/pipe-replacement/)

 and plan ahead rather than fixing one leak at a time.

It also does not replace a proper inspection when you buy an older house. If you are buying, ask about the age of the pipes, tank and heater, and look at the last few water bills for unexplained jumps.

## Keep a simple record

Write down the date, the meter readings and anything you found. Take photos of the tank, the heater and any stains. A record helps you see whether something is getting worse. It also helps if you rent the property out or later need to show when a problem started. Landlords can use our 

handover checklist between tenants

[/guide/landlord-plumbing-checks-between-tenants/ →](/guide/landlord-plumbing-checks-between-tenants/)

 as well.

## When to call a plumber

Call a plumber if your meter moves with everything closed and you cannot find the cause, if the tank leaks or keeps overflowing, if a drain stays slow after cleaning the trap, or if you see damp you cannot explain. For a water heater that trips the breaker, switch it off and get a qualified person to check the wiring. Book planned repairs at a time that suits you, after reading the 

Plumbing Costs section

[/plumbing-costs/ →](/plumbing-costs/)

 so you know what to expect.

## Questions people ask

When is the best time to check gutters?expand\_more

Before the heaviest rain months and again after big storms. In the Klang Valley rain falls through the year, so many owners check gutters at least twice a year and after any storm that drops a lot of leaves.

Does a condo owner need the same checklist?expand\_more

No. Shared tanks, pumps, risers and the roof are building management's job, so a condo list is shorter. Focus on your meter test, floor traps, taps, toilets, the water heater and any bathroom leaks that could reach the unit below.

How do I test for a hidden leak?expand\_more

Close every tap and water-using appliance, note the water meter reading, wait a few hours or overnight without using any water, then read it again. If the meter has moved, you probably have a leak on your side of the meter.

Do I need a plumber for a yearly check?expand\_more

Not usually. Most of the checks are visual and safe for an owner to do. Call a plumber if you find a fault, such as a meter that moves with everything closed, a tank that leaks, or a heater that trips the breaker.
