I wouldn't change it. Way to early. 4/1 is the ealiest I ever do it but like above it depends on how your system works and if you want to leave the heat on. My line is exposed under under the camp from where it comes out of the ground under the camp to the other side. To risky for 3/16. Once the ice is out, the lake helps keeps things warmer. Next weeks weather looks warm but in a normal year it could still dip down below 20 many nites. Your call but I would wait. I cant solder for a darn anyway.
