Yes, it does mate. Most filter systems are required to work at below the pressure that most municipalities supply water to the front gate. Just check with the vendor from whom you bought the filter system and they should be able to tell you. Our filter system has this stated on the documentation that came with it.
If your vendor cant help you, Attilio from CosmoreX Coffee is very au fait with such things and should be able to provide you with valuable advice. All the best, :)
