Background

In this example, a Villa Park home had a kitchen remodel some years ago, during which a gas line to a new cooktop was run through the attic using yellow-jacketed corrugated stainless steel tubing. During escrow, the buyer's home inspector notes the tubing and reports that no bonding clamp or conductor was visible near where gas enters the house.

The report recommends evaluation by a licensed plumber. The seller wants to address it rather than leave the question open.

What happens next

  1. Find the paperwork.The seller looks for the remodel permit and any installation records that mention the tubing brand.
  2. Hire a licensed plumber.The seller checks a plumber's CSLB license at cslb.ca.gov and schedules an evaluation.
  3. Identify the product.The plumber identifies the tubing brand from the jacket markings and reviews that manufacturer's bonding requirements.
  4. Inspect the run.The plumber checks for damage, contact with metal flues and protection where the tubing passes through framing.
  5. Add bonding.Bonding is installed as the manufacturer requires, coordinating with the electrical side where needed.
  6. Document.The seller gets written documentation of the work and any permit, and shares it with the buyer.

Two ways the seller could respond

Address it

  • Licensed evaluation and bonding added
  • Written documentation for the buyer
  • Question resolved before closing

Leave it open

  • Buyer may request a credit or repair
  • Uncertainty about the installation remains
  • Same question may come up at the next sale

Terms from the report

CSST
Corrugated stainless steel tubing; flexible gas piping with a plastic jacket.
Bonding
Connecting metal piping to the home's grounding system so stray electrical energy has a safe path.
Strike protection
Metal plates where tubing passes through framing near wall surfaces, to guard against nails and screws.

Lessons for owners

  • Keep permits and records from any gas work
  • If you have CSST, look for a bonding clamp and conductor near the gas entry
  • Bonding can often be added without replacing the tubing
  • Use a licensed plumber familiar with the specific product

Common questions

Is this a real transaction?

No. It is an invented example to explain a common inspection note.

Does unbonded CSST have to be removed?

Usually not. A licensed plumber can evaluate it and add bonding to the manufacturer's requirements.

Who decides whether a permit is needed for adding bonding?

Check with the City of Villa Park, and ask the plumber.
