Servicing the Chicago land region. Jo-Nan plumbing is a family owned and operated business guaranteeing top quality work and customer service for over 20 years.
Starting off as a sewer and water contractor in 1985, Jo-Nan Plumbing began working on new construction commercial projects along with residential. Growing into a full service plumbing shop by 1989. Owner and founder of the company John C. Lesmeister saw BackFlow water prevention as a high priority need for public safety. Ever since, Jo-Nan Plumbing Inc. started specializing in Water Safe, Back Flow Prevention, Installation, Testing, Service, and Repair. One must be a state licensed plumber, have a state licensed plumbing contractor license in the state of Illinois, and also have a C.C.C.D.I. License. NOT ALL plumbers are insured, and licensed to test these devices. Only a plumbing contractor that meets the above requirements can legally test a backflow device in the state of Illinois and Chicago. Don't be fooled by some companies who charge for the price of a licensed plumber but are sending out unlicensed persons.
