1. Correct any problems pointed out by the inspector: One of the main reasons why people fail plumbing inspections is that they have some problem with their system or plumbing line. A plumbing inspector will be able to point out those specific problems, indicating why they are not able to pass inspection. After your inspection points out these problems, you should work to correct them. If you do not have the skill to fix the problem yourself, then you should hire a plumber or a plumbing contractor to come and help you.
2. Follow any other recommendations: After you fix any of the major problems that are indicated by a plumbing inspector, then you should follow any other types of recommendations that the inspector has. These recommendations might refer to the cleanliness of the plumbing system or the types of materials used for the system. Make sure that you follow these recommendations as well, so that your plumbing system will be very safe when you have the inspector come the second time around!
3. Make sure that the work is ready to be inspected: Another one of the main reasons why people fail plumbing inspections is because the work was not completely ready for inspection. Make sure that your plumbing project is finished and ready for inspection when the inspection appointment is made! If you are eady for the inspection, then you will not be as likely to have the inspector return - and you don't want the inspector to return, because then you probably will have to pay an extra fee! If you are not sure if everything is completed (especially if you are doing some of the work yourself), then you should either consult with a plumbing contractor, or you should review a checklist for plumbing inspection standards. These standards and requirements will likely be available through your city or local authority.

Plumbing inspections are very important and you will want to make sure that your plumbing passes inspection as soon as possible! If you don't pass your plumbing inspection the first time around, then you should follow these steps to help you improve your plumbing system. By following these different steps, you will be able to better make sure that you will pass inspection next time! Good luck in your next plumbing inspection!
