Mcgivered Water Line
I just purchased a home with an older 2016ish GE profile fridge. The fridge uses a GE MWF filter but had a diverter installed I place of the filter.
I noticed the water still ran with the diverter removed and noticed that the water line was being manually routed through a different filter taped to the back of the fridge.
Why would someone do this and should I just reroute the water line back through the normal water filter?
