To promote its newly structured Pro Circle program, In-Sink-Erator is offering each plumbing contractor who applies, and is certified, an automatic entry into the Pro Bowl Sweepstakes. Contractors can enter online at www.procircle.com from Sept. 1-Dec. 31, 2005, when they apply for Pro Circle membership. Members who register and are certified before Oct. 31 will receive one additional entry.

The grand prize winner will receive airfare, hotel accommodations and tickets for two to the 2006 NFL Pro Bowl game in Hawaii. Ten first prize winners will receive an official NFL football, featuring their name and the NFL team logo of their choice.

Key features of Pro Circle membership include the Service Your Own Work program and the extended warranty program.
