I was one of the unlucky few that also needed the stack removal tool as my iron filter had a lot of iron build up.
New stack installed and working well although I suspect I only actually needed the stack removal tool V3022 and Wrench - V3193.
It was previously emitting a high pitch noise. The old stack just needed a really good clean but no harm in replacing it..
Too late for me but please consider bundling V3022 and V3193.
Even after buying parts piecemeal over 3 orders it was still way cheaper than calling a service tech, thanks for the videos.

I ordered the parts with the understanding that they would solve my problem. They didn't, and the result of which is on me. Turns out, the entire valve needed replacement.

That's the way it goes sometimes when you try to do it yourself.

Live and learn. I now have spare parts!
