Plumbing supervisor Jakub Markowski, 41, faces an investigation by the city more than a year after The Post exposed him as New York City government’s biggest overtime hog, clogging his bank account with a staggering $332,000 in extra pay during the 2025 fiscal year.

A spokesperson said the city Department of Buildings opened a probe into Markowski — who drew a whopping $465,000 paycheck from the city — after receiving a complaint into his “business practices.”

Markowski, who lives in an upscale apartment building off the Rockaway Beach boardwalk, didn’t return a request for comment. His wife Elizabeth Markwowska, 63, perhaps unsurprisingly, said he was working.

“He works seven days a week,” she told The Post from their home.

Markowski also ran two private businesses – Super Plumbers Corp. NYC and Dynamic Blue Water Mechanical — as he drew his stinks-to-high-heaven paycheck from the  New York City Housing Authority,  state records show.

In addition to the DOB investigation into Markowski’s business practices, officials said they also conducted a sweep of active plumbing jobs in which he was the permit holder to make sure they were completed safely.

The sweep found no violations, officials said.

Markowski ranks as the fifth-highest-paid city employee, according to records and the Empire Center watchdog. 

He would have had to work an average of seven extra hours a day for 365 days straight to draw his outsize paycheck, the Times reported.

His wife, Markwowska, said she was unaware Markowski was the city’s highest-paid plumber. She said he kept someone else in charge at his two plumbing businesses.
