All my taps and shower heads etc keep getting clogged up with bits of dirt. 

The water supply into my condo is full of dirty bits. I already have a 4 stage filter for drinking water. But I want to filter all the large particles out as it enters my condo.

 

Any ideas? I need the filter and someone to install it.

Lanna Water on chang Pruak road across   from  the uni should be useful.

We had the same problem - this works perfectly - easy to fit yourself or they will fit for you
