Make sure one is in stock then drain and investigate.

I think you can only buy the body on it's own [1] off eBay so I might
do that for her *anyway* and then I have the option of just the plate
/ ball valve or change the whole body.

Would it be ok to fill / flush with fresh water to check for leaks /
functionality before committing to the inhibitor?

[1] I think you can only officially buy the head, or head+body
(complete solution), not the valve body on it's own.
