I installed a Whole house filter a few years ago, it is piped out with .75" copper. They no longer make the unit and I have to buy GE filters for it, plus it very hard to replace the filters. I want to replace it with a GE, but the GE I would like to use is 1 inch. I know there would be a flow problem if went from 1" to .75" back to 1", so my question is this; is there a problem going from .75" to 1"(the filter unit) and back to .75". would this create a water flow problems?
Thanks in advance,
Joe
