How to Inspect the Gas Piping (UPDATED 9/1/17)

While the inspector is at the property they will want to inspect all of the visible gas piping. If there is any damage or gas leaks it should be called out in the report as a defect. If the inspector comes across CSST gas supply lines it should be put in the report as a defect. Please review the CSST comment that is in the software (directly below) and the rest of the procedure in this daily training post.

CSST: Observed gas supply lines in the property that are made of corrugated stainless steel tubing (CSST). Nearby lightning strikes can result in an electrical surge that can potentially puncture a hole in CSST and cause a fire. Proper bonding will reduce the risk of damage and fire from a lightning strike. The extra bonding recommended was not observed at the time of the inspection. Recommend further analysis and repair by a licensed electrical contractor. For more information regarding CSST, visit http://www.csstsafety.com

III. The inspector shall report as in need of correction:

N/A

 

IV. The inspector is not required to:

M. Evaluate fuel storage tanks or supply systems.
V. Inspect or test for gas or fuel leaks, or indications thereof.

 

Axium SOP Differences

Axium Requires: The inspector will use the gas detector on all accessible piping to search for possible gas leaks at the property.

 

Tools Needed

The inspector will use their gas detector to look for any leaks at accessible gas piping around the property.

Procedure

  • The inspector should check all visible gas lines and joints with gas detector in an unfinished basement, crawlspace, and unfinished mechanical room. Make sure to run gas detector across the entire line for flexible gas lines.
  • There is no picture required for this section unless a gas leak is found. If there is a gas leak, make sure to check it three times with the detector and a fourth time with your nose. The picture should have the gas detector in it with the brand name of the detector visible. The detector must be in the picture otherwise it’s your word against the client’s word.

Common Defects

  • Gas lines that are damaged, loose, leaking, missing, or not secure.
  • Gas lines that have moderate to severe corrosion.
  • Gas lines that are not supported, kinked, or installed improperly.
  • Gas piping that is composed of CSST (See R&R for more details.)

 

Common Mistakes

  • Not checking all of the gas piping for gas leaks (especially in the crawlspace).
  • Not identifying CSST piping properly and explaining to the client.
  • Not confirming a gas leak by checking three times with detector and once with nose.

 

Report / Software

IN


  • The interior gas piping was in acceptable condition. No evidence of leakage was detected at any of the exposed gas piping. Pressure testing is considered beyond the scope of a property inspection.

NI

  • N/A

NP

  • There was no gas supplied to the property.

RR

  • Gas piping in this home [word 1]. A qualified contractor should evaluate and repair or replace as necessary and according to current standards.
