The purpose of the Plumbing Inspection Program is to ensure that all plumbing installed during construction of a new or renovated building is installed by knowledgeable craftsmen in accordance with applicable codes. Properly installed plumbing systems protect the public’s health by preventing bacterial or chemical contamination of the public water supply caused by accidental backflow as well as by preventing exposure to discharge from improperly installed wastewater drainage systems.

The plumbing program provides oversight of the installation of plumbing systems in all areas of Montgomery County except for the cities of Centerville, Dayton, Oakwood, and Kettering.  The plumbing program is also responsible for on premise sewer and water systems in many areas of the county.  Plumbing contractors and in limited cases, homeowners, may apply for permits to install plumbing systems in new or remodeled construction, with response to inspection requests normally within 24 hours.  The Plumbing Inspection Program registers all persons engaged in the business of plumbing within the jurisdiction of Public Health.

Did You Know that if you are planning a home remodeling project and plan to repair, replace or add new plumbing, you are required to secure a plumbing permit. In turn, if you are hiring a licensed plumbing company they too must secure a permit.  A Plumbing permit will provide you with a safety inspection; which will insure that the work was done according to code.  It is not worth your family’s safety and or financial risk to skip this very important part of your project.

As a homeowner, what is the procedure for securing plumbing permits?

Homeowners may obtain plumbing permits for installations in their own home. If a homeowner wishes to obtain a permit to install their own plumbing system, they are required to complete an affidavit provided by our office, which must be notarized. Homeowners are required to post an additional $50.00 cash bond which will be refunded approximately 6 weeks after final inspection. Should additional fixtures be installed that were not indicated on the permit, or additional inspections be required above those authorized in the fee schedule, the appropriate amount will be deducted from the cash bond. If a homeowner is installing an appliance, sewer, water, deduct meter or backflow device, they will not be required to pay the additional bond, but will be required to complete an affidavit. Authorization is required for on-premise tap-in permits when performing sewer, water and irrigation/deduct meter installations. It is recommended to call Public Health or your local sewer and water purveyor for assistance. New installations or alterations for residential properties on septic systems must be approved by Public Health’s Household Sewage Treatment program prior to the issuance of plumbing permits.

Corrections required by Public Health prior to connecting to Public Water Supply:

  • Vacuum breakers and backflow preventers installed where required
  • Pressure reducing valve installed where water supply exceeds 80 PSI
  • Thermal expansion tank installed on cold water supply
  • Water heater must meet code requirements
  • No cross connections allowed between public and private water supply systems
