So when do you need a plumbing permit?
Check with your local planning department to be certain, but in general, you need a plumbing permit when “major” plumbing work is perfect where ensuring safety is an issue.
This list includes (but is not limited to):
- A remodel in which plumbing fixtures are moved.
- A re-piping
- Replacing a major drain line
- Changing your water heater (there are safety issues involved).
What are the main safety issues?
There are several and this post can mention only a few, but some mains ones are:
- You can never directly connect iron pipes to copper pipes. They chemically corrode each other. You MUST install a brass dielectric coupler between them when such as join is necessary.
- Every part of your drain system must be properly sized and sloped.
- Your water heater must be securely fastened, where ever it is.
- Your cold water pipes must be properly grounded (it is no longer permitted for the cold water pipes to be the ground, but in case anyone ever did, the cold water system must be grounded.
- Hot water pipes must now be insulated (effective Title 24).
- Your drain vent stacks must be installed correctly (this applies only to new construction and major remodels).
