Plumbing

  1. Water distribution systems improperly tested or not tested at time of rough inspection.
    1. Approved testing for water distribution shall be a minimum of 100 psi for both residential and commercial installations.
  2. Drain Waste and Vent system improperly tested or not tested at time of rough inspection.
    1. Approved water testing for DWV systems shall consist of filling the system to the highest opening with water to the point of overflow. If the system is tested in sections, each section and successive section shall be tested with a 10' head of water pressure. Water shall be kept in the system a minimum of 15 minutes before the inspection begins. (Exception: Rough plumbing testing for one & two family dwellings shall be permitted to provide a 3' head of water above the highest drainage fitting.) The final test of the completed drainage and vent system shall be visual unless it is determined that the system has been altered since the rough-in testing, this could require further testing of the system.
    2. Approved air testing for DWV systems shall be a minimum of 5 psi for a test period of at least 15 minutes.
  3. Fixtures not properly secured. Additional wooden blocking required between wall studs for proper fastening of the nailing flange at tub and shower enclosures per manufactured installation instructions. Water closet floor flanges not properly secured to the floor with corrosion resistant screws or bolts to prevent loose water closets.
  4. Improper support of and improper fall on plumbing piping.
  5. Plumbing contractor fails to request inspection of site built shower pans or second floor hydro-massage tubs that were not installed and inspected during the rough in inspection.

Mechanical

  1. Supply and return duct work not installed and sealed per manufacturer instructions
  2. Prefabricated fireplaces installed & covered without inspections or not correctly installed per manufacturer instructions.
  3. Pressure regulators are not installed or not placed in the proper position. Normally regulators should be installed in a horizontal position however check with manufacturer for all other acceptable positions. When pressure regulators are used in outdoor applications they must be afforded freeze protection. This can be accomplished by installing a vent protector such as the Maxitrol model # 13A15 vent protector or the installation of a metallic or plastic shield above the regulator.
  4. Condensation lines not installed or are not trapped in accordance with the manufacturer instructions.
  5. Improper couplings installed on black iron gas piping. Steel couplings with running threads that are used in the manufacturing process and shipped with gas piping are not permitted for gas tight installations. Approved couplings shall be cast malleable couplings. These couplings are usually evident by the gripping ridges on the exterior of the coupling as well as the non-continuous threads inside the fitting.

Electrical

  1. Front & rear exterior electrical outlets are not accessible from grade. These electrical outlets are required to be accessible while standing in the front or rear yard.

  4. NM cable & UF cable, AWG #8 and larger are limited to the 60° C column of Table 310-16. On occasion the loads served by these circuits have been calculated on the 75° C column. See Articles 334.80 & 340.80.
  5. At time of rough electrical inspection the grounding conductors have not been made up with pressure connectors inside of junction boxes, outlet boxes and switch boxes.
