Is it necessary to install this plastic piece?

[Amateurplumber1]

I bought an outdoor faucet and am wondering if it is necessary to install the plastic insert behind the flange. According to one website, it says that it helps angle the faucet downward. Thanks.

No, but if you do not, how will you anchor the fauxet to the wall?

That wedge helps achieve a slight downward pitch to the sillcock, assuming everything is flush against the mounting surface, to achieve proper drainage, see image.

Other frostproof sillcocks, like those available from Quarter Ball, angle the flange to achieve the proper pitch without using one of those wedges, see image.

There's holes for screws in both the flange and plastic piece, so without would also work. In the end, even though I'm on uneven brick, I installed it. I'm not sure I needed it, and in my application it may end up even doing more harm than good, but whatever.

It is neutral. Even if it doesn't do any "good", it cannot do any "harm".
