CSST Frequently Asked Questions
1. Can CSST be buried?
a. Yes, however it must be sleeved in a non-metallic conduit ½” larger than the pipe. The
underground section must not contain a fitting and it should be vented to the surface. If
connected to the home’s metal pipe gas distribution, it should be bonded. See section 4.10 of
the HOME-FLEX
