check valve

Refers to a careful inspection of the positioning/operation of a new/replacement one-way flow-stopper to make sure it's being installed in the correct "direction".
Zero was too stupid/unaware/forgetful to perform a "check valve" detail when hooking up the plumbing for the Camp Swampy mess hall, and so now there are geysers squirtiin' up all over da camp, but no water coming out in any of the kitchen-faucets --- just something more for Sarge to bellow about.

Check your tea

A thinly-veiled threat referencing deadly polonium poisoning.
British journalists who criticised the Russian Olympic skater Kamila Valieva for failing her drug test were advised by her comrades to check their tea.

Someone told the British media team 'You will be positive when you discover some new substances in your tea.'

Litvinenko was a former KGB agent who criticised the Kremlin. He did not check his tea, and he passed away in 2006.

If you are an enemy of the Russian state who must go out to lunch, be absolutely sure to check your tea.
