I have a dumb question regarding water filters......
We use copious amounts of fresh water on board (two dogs, fresh water flush, showers, etc.) so make water daily. In the PNW there is lots of algae so the supply water to the water maker goes through a 50 mesh stainless algae filter, then a 20 micron spun filter, then the 5 micron pleated filter the manufacturer requires. In replacing these (they last anywhere from 4 to 8 days), I see that the water flows into the middle of the cartridges, then out. This makes them tough to clean and re-use since getting the gunk out of the inside of the filter is harder than if the crud were on the outside.
Is there any reason not to plumb these filters backwards, so the flow is from the outside of the filter to the inside? I can't see one, but there may be a reason. Anyone know the answer?
