Stymied by trying to remove a fluidmaster

[Abe]

I'm a pretty handy guy, but this nonsense has got me stumped.

I'm changing out an old fluidmaster from my tank for a new one. The damn plastic nut will not loosen (yes, I know how to loosen a nut, duh). When I try to loosen it, the fluidmaster body and the braided hose turn also. Trying to hold the fluidmaster body in place is impossible because the bottom portion of the body 'ratchets' and does not bottom out. How do I got this thing off?

Naaah. Dremel.

Or a hacksaw blade

what color is the plastic body?

[Bruce Pearce]

let's try it again

if the plastic is red / brown the whole upper body removes with a pushdown and twist

if the body is gray hold the column at the base with a vicegrips as the lower tube is adjustable in height for differing toilet depths
