hello, I will be replacing hose bibbs & gatevalves on each 3/4 zone pipeline , due to tight corners I want to add unions to each zone pipe to easily remove pipe & replace parts, unions will also help remove pipe out of way when replacing boiler in near future.I would appreciate any recommendations on my thought process & also will attach pictures as reference Image may be NSFW.
