u may wanna ask them to show u how the filter looks like after installation...

Most of the membrane filters in malaysia are HOLLOW FIBRE MEMBRANE and they look like this after installation (on the left) while we actually got our supplier to manufacture a better design (on the right) with new generation membrane MultiPore system

You do regular back wash, is ok. There also the timer will do daily 1min back wash. My mom membrane filter already more than 5 years. Only recently the piping outside leaking, and the timer die plus membrane need replacement so plan to try other small.  I remember membrane is about 400+ few years back.

And btw, my mom house piping not ugly, is all about how the installer do for you.

Is depend the space, how is being installed and was the preparation work done earlier for filtration piping or not. There are plumber installing it "cincai" and look ugly there plumber installing it neat and nice. If I sell a product, i can give you a neat completed product photo to market to you.

You can take photo of how your incoming are, and consult the filter seller or installer, ask them draw how the piping flow or you can plan your own and ask them to confirm if it work.

Forgot already, many years back got it from expo, and they came install, after that did chemical backwash for few time. Now lost the contact and didn't came do chemical back wash. Thinking to change for other type to try out.

Yeah will check that out too. Need to recover from the Amway filter "wound" first.

Hi, So you also bought the amway external water filter ya?
