No. Polyethylene gas pipe, no matter who manufactures it, is not to be used in a building or under a foundation with a structure on it. Not only is it against all codes, it is potentially dangerous.

No, all yellow gas pipe needs to be at or below code-mandated burial levels. The yellow poly pipe should never be above grade.

Yes. It is certified for use with Propane as well as Natural Gas.

Yes. Unlike some push-to-connect fitting manufacturers, our underground fittings can be disassembled and reused.

We recommend you check the entire system for 30 minutes at 15psi. Overnight testing is not recommended due to “false positives” that may result from temperature and barometric changes.

No, they are completely different product lines and are not compatible.

No, the product line is purpose made for direct burial and does not need to be wrapped nor put in a conduit.

No. Unlike some push-to-connect gas fitting manufacturers, our gas pipe does not need to be chamfered prior to installation of its compression-type fittings.

CTS means “copper tubing size” which is significantly different that “IPS” (iron pipe sizing) which is most prevalent in the underground gas category today. So, even though your pipe may say “1/2” CTS” it will not work with ½” IPS pipe fittings.

Yes. We have a ½” IPS to CTS conversion fitting. Part number 18-429-101. No other sizes are currently available.

No, the riser may never be altered. The PE end may be cut slightly shorter. We suggest you dig the trench deeper under the riser to adjust your installation level.

Yes, so long as the pipe and fitting sizes are the same. All manufacturers of D2513 poly pipe are held to the same dimensional and material standards.

This means “standard dimension ratio” It is the ratio of a pipe’s average outside diameter to its minimum wall thickness. If adding to an existing underground gas installation, always ensure that dimensions are the same.

Absolutely! Please check out our fusion guide in the “resources” section of the homeflex.com website.

No, they are dissimilar materials and cementing/bonding would be an issue. Further, they are not certified for use together.

One must know the lineal length of the entire installation. You must also know the total btu/h of all appliances drawing off the gas piping system and, finally, you’ll have to know the system pressure and capabilities of your natural gas meter or LP tank regulator. Once those factors are determined, check out the sizing guides in our Design & Installation Manual available at homeflex.com.

Absolutely. We have all sizes of transition fittings and meter risers (1/2” through 2”) that will enable you to make that metal-to-poly transition. Further, we recently introduced a new conversion fitting in ½”, ¾” and 1” sizes. Check out part numbers 18-436-005, -007, and -010 at homeflex.com or at homedepot.com.

Typically, underground gas systems run at 1/4-10psi and are stepped down to ¼ psi for natural gas and ½ psi for LP gas via a regulator either upon entry to the home or at the individual appliances. Our underground pipe is rated for a maximum of 80 psi and our fittings are rated for a maximum of 125 psi. All spec/submittal sheets are available in the “resource” section of homeflex.com.

This is a 14-gauge or thicker wire that is installed beside the poly pipe prior to burial. It extends to the surface and is wrapped or zip-tied around the riser. A detection service can connect their equipment to the wire and determine the underground routing of the gas pipe prior to digging. HOME-FLEX^® tracer wire is available at homedepot.com (model # 18-TW100/250/500).
