Use and Care Manual
CAUTION: UNDERGROUND USE ONLY
HOME-FLEX
TM
Underground pipe must be installed in accordance with the
Installation Guidelines outlined in this document as well as all local
plumbing, mechanical, electrical and/or building codes and laws applicable
at the locale where HOME-FLEX Underground is to be installed. If you do not
understand all aspects of the installation requirements and local codes,
locate a qualified installer in your area who does.
This is IPS (Iron Pipe Size) sized Medium Density Polyethylene (MDPE) Yellow Poly
Gas Pipe intended for underground piping of Natural Gas or Propane.
1. Never use HOME-FLEX Underground pipe and products in above-ground
applications.
2. Never use HOME-FLEX Underground pipe and products inside buildings.
3. Never encase HOME-FLEX Underground pipe and products in concrete.
4. Underground gas piping must be installed with sucient clearance from any
other underground structure to avoid contact, to allow maintenance, and to
protect against damage from proximity to other structures. In addition,
underground plastic piping shall be installed with sucient clearance, or shall
be insulated from any source of heat so as to prevent heat from impairing the
serviceability and reliability of the pipe.
5. When installing HOME-FLEX Underground pipe, care must be taken to avoid
inducing excessive stresses to the pipe and fittings.
6. Excessive bending of plastic piping systems, particularly at joints, can exceed
stress limits and result in failure. Pipe, when joined with fittings, shall be laid
as true to line as possible, while taking into consideration that common MDPE
gas pipe may expand or contract 1 inch for every 10º F of temperature change
per each 100 foot section of pipe. Grading and backfilling must be carried out
carefully to prevent uneven settlement and therefore excessive bending.
Please refer to ASTM D2774 for additional information on backfilling.
7. The use of damaged pipe where the joint is being made must be avoided. If
there is a cut or groove in the pipe, that section should be cut out. Sealing
performance can be aected by scored or damaged pipe, so caution should be
taken if present on the pipe.
8. HOME-FLEX Underground gas piping system must be pressure tested for leaks
and inspected in accordance with all local codes prior to being put into service.
