Hi,
I'm staying at Condo. And today, neighbor from downstairs informed that there's water dripping from the ceiling of his toilet (as Video shown).

Before I call the contractor, may I have your advice from your previous experience?
My doubt is whether it's caused by floor leaking or pipe in the wall cracked? Can you tell?

Hi, couldn't see the video, perhaps you can try reupload it

Meanwhile, if the leak is a consistent stream / the water leaked is colored (i.e. brownish or soapy) chances are its the pipe

If its white and leaves a crusted stain after wiping, its floor / cement cracks

go to your water meter, observe the running numbers.
dont use water at home for 30min, come back see again.

if numbers increase, means you got clean water leak.
repeat the test by switching off parts of your incoming, eg to toilet

if number no increase, means is dirty water leak. can be toilet, sink seals fail.

in both case, need to call in plumber.

if your house pipes are blue ABS, no need to investigate, straight change whole house pipe.

Appreciate all your advices and suggestions!

Ya hor, don't know why video wasn't attached?!🤔
But my pipe has converted to PVC, shouldn't have brownish water?

Oh? Mine is Blue Pipes leh... Why so sure it's that issue? Always cracked?

You shouldn’t call your plumber. You should ask your management office arrange person to check where is the source of the leak. Sometime the fault belong to the owner below - not yours. Follow strata law to solve this

ask your building mgmt first before hiring any plumber. normally, mgmt have dedicated plumber to check all this thing. if the plumber said you need to hire outside plumber to fix the issue, then only go for it

get ur management to check. usually anything above, the unit above must fix it by strata law.

Usually the gully trap will be the first one that will leak below when it is not properly waterproofed..

That is not true. There are times the pipe that leak belongs to owner below

I got the idea but our management owned by the resident, haha ...
In fact, I'm curious, it could be leak from unit downstairs?any piping on the ceiling?

Our old place a little special, as mentioned, managed by resident, haha ... Most probably deal between relevant units.

I'm the Upper Unit 🤣

*Sad that could not attached video. Someone could help?*
From the water dripping pattern, I'm curious whether it's floor leaking or pipe inside the wall cracked?

Any idea how to...?

Sorry, I still can't attach video. Hopefully the screenshot picture would let all understand a little about the leaking point.


Attached thumbnail(s)

well that is what i was told by JMB rep unless the leak is clearly reported as unit below's fault

better also get a third party contractor/plumber to give his assessment la

Looks like your toilet is covered with plaster ceiling.

So your downstair neighbor got leaking from the floor, is obviously from your toilet.

From my experience, got a few potential point

1. Water floor trap side dun have good finishing, hence water go in seep inside

2. The WC dun have proper water proof at the bottom during installation

3. The floor dont have proper water proofing or floor cement crack due to floor expand from heat or minor shaking, so causing the water proof layer to tear off, hence got leaking.

Quick solution is using PU injection from neighbor toilet ceiling. They will drill a few holes and inject the solution and hardened up.. so lesser mess to ur side..

If not u need to crack all tiles and redo .. bigger mess.. will cost u around 3k to do it

Wow... Wow... Real experienced advices! Thanks!
Anyways, the floor should waterproof good enough since renovation 15 years ago! And, I think your 3rd point perhaps the issue of the current incident!

Ok. The injection, yes I saw that works before in my office! And it seems quite work well ya!

Another consideration, whether those Acrylic Waterproof Liquid products Ok for my leaking issue? I heard many of them out there used it and quiet happy with the result! What do you think?

Lastly, as your experience, that's definitely not the Pipes Cracked (inside wall) ?

These 2. Re gully trap, if old condo, just need to replace the screw in cap.

Thanks! In fact what is Gully Trap? And, which screw in cap means?

Update:
6 hours of Not Using Toilet, neighbor reports "Still Leaking/water dripping"!

What does it mean?

It means internal piping is leaking water.

Find the plumber that use sonar to identify leaking point. No need hack.

Fast and efficient. Don't use low tech plumber. He go hack all your ceiling and floor you will die.

Another confirmation is turn off all water.

Release all water until all pipe no water

Flush the toilet bowl until no water

Stay one night in hotel



Then come back ask if the leaking still got

If don't have 100% pipe leaked
