Thank you for the video! I followed it step-by-step and found this part to be leaking.

As you can from the video is dripping on idle. It's rather puzzling because I find:

- all o-rings are in good shape. The exact size and thickness is hard to find even if I want to replace it
- the one part that is broken is this clamp but I don't think it's the issue, also can't find the replacement (not even sure I'm calling it correctly

Is there any specialists that repair or service water purifier?

Lifesaver I'm trying to find it on shopee what is it called exactly?

I forgot to attached the video so here's the leak.[attachmentid=11506120]

However when I applied pressure to it the water leaks went somewhere else like the bottom of the water filter so could this be a water pressure issue? I tried to close my tap and lil but to no avail.

I have finally fixed it! This wheel base thing was really the culprit. From my untrained eyes I don't see anything wrong with it, no cracks whatsoever. The only thing I suspect is the larger washer (not in the pictures) that rest inside the casing which seems flatten.

Less than rm40 to fix and 3 weeks of headache, not bad. Thanks for the link to the video I won't have known how to take it apart!
