Does anyone have an auto bleed setup diagram which they could share with me? I have a Bosch SM 3T SCW geo system for my cabin. The drain line that it would need to hook into is about 3 feet above the furnace, proper. My installer wants $1800 to add the auto bleed which seems kind of rich. I haven't had any problems with the system as I have a tenant currently and the well water naturally bleeds with his usage. But someday I may lose the tenant in the dead of winter and it would be nice to have a backup plan already installed.
