I have two filter on the pipe coming from my well. A 10" narrow 20 micron filter and a 10" wide 5 micron filter. They probably don't help water flow much, but are necessary to get decent water.
At garage sales recently I bought a sand filter and a 20" narrow filter housing (it takes two 10" narrow filters). The sand filter flushes easily, and I have a lot of sand.
If I pulled the 10" narrow 20 micron filter and replaced it with the 20" narrow 20 micron filter and the sand filter would you expect my flow to go up? I am figuring the sand filter shouldn't change much except to keep the first filter cleaner, and the 20" should have less resistance than the 10".
It would involve a fair amount of work, but better flow would be nice. And I sure don't want to do it and find the flow is worse for some reason I failed to anticipate.
