hey guys winterized my water system by draining and filling with antifreeze. I think it did not totally drain had problem with clogged filter screen. did not relize it was clogged water stopped coming out of faucets so I thought it was empty. filled 10 gallons antifreeze and nothing came through then relized I had to clean the screen. opened faucets water came out first then finally the antifreeze came out. I am a little nervous now thinking that the antifreeze is diluted with the water. Will I have a problem, I used -50 antifreeze. someone said I should be ok but that I should help the system stay vented by opening the relief valve on the water heater????????<br />Boat is already shrink wrapped/I have a zipper door to get in if I have to. <br /><br />Thanks<br />Cool it
