I installed a SeaGull IV drinking water purifier when doing all this other plumbing. I had tried the regular water filters you can get from boat stores or Home Depot and found that they did not remove the tank taste. I am hopeful that the SeaGull purifier lives up to its reputation as taking out all tank taste. This filter is only for drawing drinking water from the tank. It does not purify all the boat water.
