Whirlpool arm - pointless on a homebrew kettle

[Brewer #416886]

Given that the gauze filter on the exit pipe of electric kettles crosses the middle of the kettle, won't using a whirpool just cause all the trub to accumulate on it?

Also, I have a Brewmonk kettle with recirculation pump - I have two concerns using this for whirpooling:
1. it isn't supposed to be used at boiling point as it can get damaged, I would have to wait too long for it to cool down?
2. blockages / damage from material flowing through it

If I were to add a whirpool arm, would it be better to have it at the top, middle or bottom of the kettle?

Any thoughts much appreciated.

Not sure what would be damaged, it just won't pump if it is near boiling as the suction will cause it to boil in the pump and vapor lock. Most people whirlpool once the liquid has dropped below 190F to avoid this

Always the bottom, you want the whirlpool jet to shoot at the shielded inlet.

All that said, if you have a column in the middle like most all in one, not sure it will ever actually get spinning enough to matter.

I've been whirlpooling for years and use electric, I have mine near the top just because I like to see it happening, near the bottom and you can't tell sometimes, as far as the elements it does coat but is easy to clean off if you clean as you go, harder the longer as it sets
