How do I replace the KDF/GAC filter when it stops removing chlorine?

A. Remove the filter housing using the wrench supplied with your water filter system. The housing has two parts: the base with the metal fittings, or the wide part, and the longer half, called the sump, that screws into the base.

Place the wrench over the narrow end of the sump housing and move towards the wider end until it stops. Turn the sump counterclockwise to remove, keeping it over a sink or pail to catch the water. Remove the old cartridge and slide the replacement cartridge into the sump part of the housing with the gold end down (it will only fit one way); on the top of the cartridge you'll see the words "this end up."

Place the base of the housing on the sump and tighten (clockwise) completely to prevent leaking.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
