Has anyone changed just the top of a Spirovent? I have one on a system that is not working/weeping/corroded. I'm going to flush the system of old antifreeze (previous service company never checked it) and refill as needed. I can't change the complete Spirovent as it's piped in steel into the circulator manifold (8 zones). Thought about splitting a new unit and swapping the top. Thanks

    Yes. use a razor knife to split the seal 1st. Then get a couple good wrenches.

    You can remove all the internals and swap them.

    You can choose to do what you want, but you cannot choose the consequences.
