In the description for the carbon filter kit that MoreBeer sells they state that the filter should be disassembled and stored dry when not in use. That's what I intend to do with the filter setup that I just put together with parts from Lowes.
I had a similar experience in England about 30 years ago.dibby33 said:remember that you can contact your local council / city people and ask them for a water report to get the chemical breakdown. Just explain to them that you require it for making beer and they are happy to provide. Here in Hobart I got it back within days with the person sending it wishing me happy brewing!
