BROWN BAG LUNCH
PLUMBING INSPECTION ITEMS
CITY OF NORMAN | PLANNING DEPARTMENT | DEVELOPMENT SERVICES DIVISION


1. NO AIR PRESSURE INDICATED ON TEST GUAGE

Question:
If inspection is delayed from the time we call it in and the city does not respond within certain time period should there be a penalty? (Code only requires to hold pressure for 20 minutes).
Conclusion:
The Building Inspectors have the authority to waive the penalty fee for (DP) inspections due to “no air on gauge”.


2. SEWER RISER “AS BUILT” MUST BE PROVIDED ON-SITE BEFORE BUILDING SEWER INSPECTION.

Question:
Is the sewer riser “as built” required to be provided on-site before the building sewer service inspection?
Conclusion:
The “as built” diagram of the sewer riser needs to be on-site and will continue to be reviewed by the Building Inspectors.


3. SANITARY TEES.

Question:
If no water or waste water can’t these be used? Especially under kitchen sinks where space is at a premium?
Conclusion:
Sanitary tees may be laid on their back under residential kitchen sinks for the purpose of venting the kitchen sink drain by use of an air admittance valve.


4. BACK FLOW PROTECTION FOR HAND HELD SHOWER.

Question:
City requirements are to install backflow protection for hand held shower. Certain manufactures, Delta, for example, state they have back-flow in their fixtures. Why doesn’t the city accept manufacturer specs?
Conclusion:
Hand held showers conforming to ASME A112.18.1 or CSA B125.1 may be approved.


5. ROUGH-IN/TOP OUT INSPECTION.

Question:
Will the city require flashings on the rough-in/top-out inspection?
Conclusion:
Yes. The flashing is required as part of the rough–in (top-out) inspection however the Inspector may approve the inspection with exception to allow other work requiring inspection to proceed until such time as the installation of the flashings can be verified. No penalty is charged for this service.


6. PURPLE PRIMER.

Question:
Is there an alternative to using the purple primer on PVC?
Conclusion:
Presently purple primer is the only code approved material to prepare the joined piping surfaces for glue however contractors may submit alternative product literature for review.
