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

I dunno how your piping work, but usually the pipe will not go so near with the drainage pipe...

Old condo pipe some are pipe go from ground and go up.. some are from up to down..

But for ur case, maybe u ask for drawing from management..
And usually condo unit pipe rarely burst one la... usually la
If there is a burst, the leak will be very powerful and spread round round area watermark one.. i dunno for ur case la.

Best option now is do PU injection and hope it works..
If dun works, then only do hacking..

Water pressure low in old condo is very common..
Probably due to common pipe outside already rusted inside with dirt and mud eating up the spaces already. Or u got a outdoor filter never change.. or u are staying at the top 2 floor and condo do not have water pump to pump pressure.

If pipe burst, will maybe temporary solve using pu injection.
Pipe burst case ofcuz is change the whole pipe lo.

But since u say is from top to down.. meaning that pipe is ur downstair neighbor sendiri punya pipe lo..

Like this lok hai lo..
Do a new one from inlet to all over ur place lo.. haha

Full.. so wad u plan to do?
Hack and lay new pipe? Or use install pipe using hidden by trunking? (Mean outside laying pipe)

Well it actually depend on your condo how it is build..
If u got plaster ceiling.. then run from plaster ceilng top lo..

If not then put trunking lo.. haha..
If bare laid.. then also ok one.. but will sekat dust and see nail rust at those support point

Good quality grey color pvc pipe will do.. make sure they seal the join properly to avoid joint leaking

Stainless steel will be expensive

Whole house will cost less than 3k la i guess since is a condo..

Hack n find pipe.. tile and replace.. then when hack tat time maybe other parts of pipe weaken by the hacking shake..
Then next time other place burst again.. lol
