Landed house or condo unit? The answer changes.
Landed house
Air Selangor looks after pipes up to your water meter. Pipes after the meter are yours. A meter that keeps moving with every tap closed points to a leak on your side. Roof tanks, booster pumps and outdoor drains are yours to look after too.
Condo unit
Building management looks after the shared tanks and main pipes. You look after the pipes inside your unit, including your floor trap, taps and toilet. Ceiling leaks from the unit above follow the Strata Management Act 2013 process, with an inspection and a Form 28 Certificate of Inspection.
Who is responsible for a leak or repair?
| Where the problem is | Landed house | Condo unit |
|---|---|---|
| Public main and pipe up to your meter | Air Selangor | Air Selangor, then building management |
| Shared tanks, pumps and main risers | Not applicable | Building management (JMB or MC) |
| Pipes after your meter or unit valve | Owner | Unit owner |
| Ceiling leak from the unit above | Not applicable | Decided by inspection and Form 28 |
| Repairs in a rented home | Usually tenancy agreement and cause | Usually tenancy agreement and cause |

Why this handbook exists
Most people face a plumbing problem without knowing if it is urgent, what it should cost or who is responsible. This handbook explains each problem in plain language, with one guide per plumbing problem, for the way homes in Kuala Lumpur and the Klang Valley are actually built and supplied.
We do not sell repairs, give quotes or take bookings. Where a guide says you need a plumber, it names one partner provider, KL1 Plumber, and says who that partner is.
Written for Klang Valley homes
Guides cover homes across Kuala Lumpur, Petaling, Hulu Langat, Gombak and Klang districts: terrace and semi-D houses with roof tanks and booster pumps, older Petaling Jaya houses with galvanised iron pipes, and condo units with shared risers and floor traps.
- Kuala Lumpur Cheras, Kepong, Setapak, Wangsa Maju, Sentul and more
- Petaling District Petaling Jaya, Subang Jaya, Shah Alam, Puchong, Damansara and more
- Hulu Langat District Ampang, Kajang, Bangi, Semenyih

High water bill? Check for a hidden leak
Close every tap, take two water meter readings a few hours apart, and our free calculator turns them into litres lost per day. It is the quickest way to confirm or rule out a hidden leak.
Home plumbing questions in Kuala Lumpur
Is a leak before the water meter my problem or Air Selangor's?
In a landed house, pipes up to the customer's meter are Air Selangor's responsibility and pipes after the meter are the owner's. Report a leak on the supply side to Air Selangor; a leak after the meter is yours to repair.
How do I check for a hidden leak with my water meter?
Close every tap and water-using appliance, note the meter reading, and check it again after a period with nothing running. If the meter keeps moving with every tap closed, there is likely a leak on the owner's side. Check toilet cisterns and the tank first, as they are common hidden sources.
Who pays for a ceiling leak from the unit above in a condo?
It depends on the cause. Under the Strata Management Act 2013 and its 2015 regulations, building management inspects the leak and issues a Certificate of Inspection (Form 28) naming the cause and the responsible party. Confirm the process with your building management; this is not legal advice.
Does a plumber need a permit in Malaysia?
Yes, for work on water pipes and fittings that carry water from the public mains in Peninsular Malaysia. That work needs a plumber with an IPA Type A permit from SPAN, the National Water Services Commission. Ask to see the permit and confirm details with SPAN.
Is there a charge just to inspect a plumbing problem?
Often, yes. KL1 Plumber's published on-site checking fee is RM30, waived if the quotation is accepted, while its water pump inspection is RM80 and is not waived even if the job goes ahead (read 15 November 2026). Ask any plumber how their fee works before the visit.
Why does my water heater keep tripping the breaker?
Usually an electrical fault in the heater, such as a failing element, moisture, or a wiring problem, is making the ELCB or RCCB trip. Stop using the heater and have a qualified person check it. Do not keep resetting the breaker.
