About Thad Ellet Plumbing

Thad Ellet has almost three decades of experience under his belt and specializes in service plumbing, trenchless sewer lining, and backflow prevention.


Thad started Thad Ellet Plumbing in 2008 after working for several years under the name Ellet/Cockrum Plumbing. The company has grown exponentially since then, warranting bigger equipment, more space, and a larger staff. The company has moved several times over the past five years: from Cambria, to downtown Carterville, to its present Herrin location on 16th St.

Thad’s wife Kate, a native of Harrisburg, joined the TEP team as Financial Manager in 2009.


Before becoming a plumber, Thad served his hometown of Carterville, Illinois as a firefighter. In his youth, he considered a country music singing career, and enjoys weekend trips to Nashville, Tennessee. He resides in Herrin with his wife and two sons.




Our mission is to bring quality, affordable plumbing service to Southern Illinois. Thad Ellet Plumbing strives to treat your home and business as its own. That is why our technicians wear booties over their shoes and place their tools down on mats.

Prior to making sure your pipes remain in proper working order, TEP technicians take the time to explain the nature of your problem, as well as any possible solutions. They always quote prices before performing work, and never begin work without the client’s approval.

Thad Ellet Plumbing strives to ensure that every one of its clients receives the time, respect, and quality service they deserve.
