I have the freshwater shower option (seldom used) which I've converted to a freshwater washdown by simply inserting a T joint which allows the water to be used by either the shower head or a handspray. The problem is that the freshwater tank is only 10 gallons and requires constant refilling. I'd like to convert my livewell to a raw water washdown. I suspect the livewell pump is smaller and less powerful than the typical raw water washdown pump. Has anyone out there tried this. Any negatives I've overlooked ?
