I have a 2023 Solitiude 380FL-R. Wondering if there would be any downside to adding a bypass to the Flow-pur on board water filter so I can drain and remove the housing and just fill the rest of the system with antifreeze. The only downside I can think of is maybe the o-ring in the housing would dry out before the next use, but that could be overcome with some silicone grease.
