Inspections include on-site administration of the Maine State Internal Plumbing Rules. A Local Plumbing Inspector (LPI) performs inspections. Inspections include on-site compliance checks of the installation or replacement of water distribution and drainage pipes, fixtures and other applicable plumbing work.
Internal plumbing inspections require a twenty-four hour advance notice. The Plumbing Division attempts to accommodate busy schedules. It is the responsibility of the person doing the work authorized by the permit to notify the LPI.
The piping of the plumbing, drainage, venting and water distribution systems must be tested with water or air. It is the responsibility of the person authorized by the permit to conduct the water or air test in the presence of the LPI.
Internal plumbing inspections usually involve two on-site compliance checks by the LPI. The first inspection involves a drainage and water distribution rough-in check. These tests are commonly performed while the permit holder and LPI has full access to all plumbing systems. The second inspection is a system final check.
The system final check includes, but is not limited to, toilets flush properly, no leaks, hot water is of proper temperature, hose bibs have vacuum breakers, rooms have proper ventilation, fixtures are secured, shut-offs are in place where required. Internal plumbing inspections are performed Monday thru Friday 9:00 AM to 3:00 PM.
