I'm replacing an old CH header tank with a 4 gallon Polytank from Screwfix. This is for an open vented CH system.
The old tank has mains feed, outlet, vent pipe and overflow (and no lid).
The new polytank comes with connections for the mains feed, outlet, and overflow, but nothing for the vent pipe. What do I need to buy to connect the vent pipe to the tank?
Also, as the new tank has a lid, does it need an air vent on the top somewhere?
I recently fitted a larger polytank header tank for our HW system and it came with both a breather and a means of connecting the vent pipe, but they're not in the 4 gallon tank kit.
All help appreciated
