Hi wanted to ask advise on water leaking issue at my house. I live in a double storey house. I've detected a leaking at the stop cork below my ground floor kitchen sink. As the pipes are concealed, i've requested the plumber to re-pipe (external) from main to my water tank to bypass the internal pipes. After repiping, the stop cork area is still leaking water after 3 days.


I was thinking it could be residue water in the internal pipes that haven't cleared, but it seems to be still leaking after 3 days. Anyone has similar experience and how you resolved it?

It was my idea to repipe as there is problem with my internal pipings, it is giving way one by one. Most of the other residents in my Taman also face the same issue. Hmm..maybe it is a good idea to ask him to check if the rubber seal worn out at the stop cock. Anyway since the pipes have been bypassed, there shouldn't be any water running through the said pipe right? My friend has asked me to monitor for another day or two to see if it is the remaining water in the pipes. Thanks.

Hi this is the picture of my stop cock. It is below my kitchen sink.

Hi Mini Orchard,
For the water to my kitchen sink it is from the roof. My kitchen is at the back of the house. So there is a new external pipe from the roof which connects back from the back of the house to my kitchen to supply the water to my sink. Yes, you are right, there shouldn't be water in the old pipe. I am still trying to figure out the issue.

When i close the stop cock, water still flows out.

Thanks for all the inputs. I will take into consideration. Will update how the issue is resolved here.

I've removed the stop cock and there seems to be no water coming out of the pipe. But there are water seeping out from the surrounding surface of the pipe. I'm just thinking now it could be a leak from the neighbour as I am living in a double storey terrace house and share the same wall with a neighbour.

Yes i agree, with this experience, quite fearful of concealed pipes now. Once there is problem, it can be a nightmare.

I requested my neighbour to switch off the main supply for his house. After one night, the leaking stopped. The leak is coming from my neighbour. Moreover, my neighbour's house is slightly higher than mine.
