FLANGE WITH BLEEDER DRAIN WITH SHUT OFFS

Here is the most unique flange set you can buy. It is lead free brass and has a built in fill valve and bleeding system. The biggest problem with pump failure is the air locking in the heat exchanger. There is no way to remove the air but by using water pressure to flush the air back to the stove. This also allows for filling the stove from the flange as well. It is made of NSF372 and ANSI61 lead free brass with built in ball valves.
