The water pump provided by HH emit high pitch bang bang sound like machine guns... Initially I thought that is normal but I begin to realise the golfers looking at my house whenever someone is showering on 2nd floor... (Initially I thought they are admire me showering..) Finally I realise my pump is really faulty..
The german pump (can't remember the name is selling at 1500rm..) I found a good alternative at the DIY shop beside the kopi shop at Bukit Indah 2.. just outside Nusa Idaman..
The brand is GCE... from Korea.. price is 350rm.. I got it installed and think it is not bad, very quiet and sufficient for 3 persons to shower (in different rooms of course) at the same time.... For guys with water pump issues and don't want to spend >1000rm, can consider this..
Lobang to share..don't say I don't tell you!
