Hi guys, wanna ask that why there is still dirt come out from the pipe even outdoor filtration has been installed? (has backflush the filter multiple time, but the water filter has been installed many years ago). Is there any solution for this issue?

is the dirt water seen at output of filter or from the tanki ?

if confirm from filter then
how many years is the sand in the filter ?
the filter sand need to change at least every 3 years.

Corrosion of GI pipe after the filter.

from the filter. I guess already over 3 years. as this filter was brought by my parent and they dont even know need to change the filter sand. The filter looks like below. is it changeable?

the dirt only comes out occasionally, maybe is like the person above said is because the filter did not change for too long

ok this one is a sand filter . yes can change the sand in the filter . every 3 years . need to call the service tech to do . in KL will cost about 350 RM to change the sand filter.

the filter system need backwash every 1 to 2 weeks depends on the incoming water quality .
i guess your parents did not do backwash cos dont know about it.
i guess long time not do backwash so much dirt stuck in the sand filter.

I use an automatic timer to turn on backwash.
Much more convinient...don't have to go out and manually turn on the tap to backwash everyday.

Timer doesn't work on this sand filter.
Yours should be membrane filter.

Yaya, it's membrane filter.

With that price you might as well buy a new 1 and install yourself

350 rm for a new one ? please provide link
you bought this or talk only ?

what sand type they put in the filter ??
is overall product Quality good ?

I found this less than 300 je,

If you survey around hardware stores some really throw the price as low as 180 also can get but exclude installation
Sand type filters usually are cheap, UF je expensive and doesn't really last long need frequent maintenance
Quality wise are debatable and subjective unless you go test the water quality each time you change the filter

i will not buy if i dont know the Quality . and specs info about the product and some figures
you need to evaluate the product. so no need to debate about quality.

what is important is the sand they fill and the weight . you need to see the specs

compare with this sand , need 2 bags / filter = 320 RM

Better to buy something you know is sure good,
you need to check this !
