Changing the water filter

I’ve written about the water situation in Penang in the past.  Water from the tap or faucet is supposed to be clean enough to drink.  That’s what they say anyway.  I won’t drink it unfiltered though.  I’ve got this water filter right outside where the water comes into the house.  I have to change the filter every month, and here’s some photographs to show you how necessary the filter is.

Our water filter is hooked up right next to the meter on the pipe going into the house.  All the water flows through it.  It has been a full month since I last changed this filter.

The technician who installed the unit told me that we get pretty good water pressure at our house.  Above average, he called it.  What he installed is the 5 micron filter.  We have strong enough pressure that we could consider using a 1 micron filter without worrying that the water pressure in the house will be reduced to a trickle.

Once the water main is turned off, I open the housing for the water filter to change it.  The unit came with this special wrench that fits over it perfectly.

As you can see the water filter is catching a lot of dirt.  I don’t want that in my showers or my drinking water for sure.

Drinking water filter

I don’t think this water filter is good enough for my drinking water either.  I have a kitchen sink water filter that I use for drinking and cooking.

I had this unit installed in July.  The first stage uses the same filter that is outside on the street, the 5 micron filter.  The second stage, the one on the left, is a carbon filter.  I’ve yet to have to change either of these filter.  The first stage is not showing any signs of dirtiness, mostly because the water that passes through the outside filter will pass through this filter.

The second stage filter probably needs to be changed soon.  It’s the one that catches the stuff that’s alive in the water — the microbes and such.  So I’ll go get these done soon.

How much?

The outside unit cost me RM 80.  The inside unit cost me RM 120.  The water filters themselves are RM 20 for a pack of 5. I think it’s been a great investment in the health of my family.
