Can the stiffeners be purchased separately? I may have lost one ( or it was not in the package to...

Asked by Slug October 31, 2020
1
Answer

Hi, Slub - No, the stiffeners cannot be purchased separately as they are included as a component to the actual fitting. If it was missing from the package, simply return it to The Home Depot for an exchange. FYI, the stiffeners may not be easily seen in the unopened package as they are inside the actual fitting.

Would gophers be a problem with this product?

Asked by soupson October 4, 2020
2
Answers

I’m not sure if gophers would bother this, but the pipe is very thick. My experience is that this needs to be buried more than 24-30” deep to meet code. Not likely a gopher will go that deep but it’s possible. FYI I’ve had gophers in an area where mine is buried but to my knowledge they have not messed with it. I’m 30” deep.

in extremely sandy and rocky soil, can Underground Yellow Polyethylene Gas Pipe be placed in a PVC pipe as a conduit

Asked by Jmac September 6, 2020
1
Answer

Hi, JMac - Putting the HFUG gas pipe in a pvc sleeve would be somewhat redundant and costly. We always recommend that you consult the codes for your local area keeping in mind ASTM D2774 "Standard Practice for Underground Installation of Thermoplastic Pressure Piping." Generally, rocks over 1/2" should be removed and a smooth, flat, somewhat sandy base be used and the trench immediately around the pipe itself should also be backfilled with the same type of sandy soil. Your local codes and/or inspector may require something different however, so that is why it's highly recommended you check your local codes.

does this piping require to be grounded?

Asked by John August 11, 2020
1
Answer

Underground PE gas pipe does not need to be bonded. CSST (corrugated stainless steel tubing) above ground / in-building lines need to be bonded. Suggest you refer to our manuals available on HomeFlex.com or copy/paste this link: http://homeflex.com/underground/#installation. While on the site, you can also check out the CSST installation manual just for reference.

Does the stiffener come with the coupler?

Asked by Amateur July 7, 2020

Answer

Yes, each fitting comes with the proper number of stiffeners.

Asked by snake June 5, 2020
1
Answer

Hi Snake, Yes this coupler will work with the 1/2" IPS meter riser. There is a typo. 1/2" IPS is DR 9.3 not DR 11. For more info please give me a call. (661) 257-3923. Ask for Jon. I am here from 8-5 Los Angles time, M-F.

How deep in the ground should this pipe be buried?

Asked by Ralph May 28, 2020
1
Answer

Hi Ralph, The minimum required trench depth is specified by your local plumbing code. The amount of earth covering your gas piping system will range from 12 inches to 24 inches. Check with your local jurisdiction. Here is a link that you can copy and then paste into your web browser. It will take you to the HOME-FLEX Underground System Design and Installation Manual. This manual will provide you with some general information.

Can this tubing stand to have small rocks in the backfill"?

Asked by Reggie May 7, 2020
4
Answers

Hi Reggie, Your local code will dictate the proper back fill for your trench. generally speaking, you will have to screen out any small stones that are larger than 1/2" Some codes will require that you create a bed of sand and partially back fill with sand. If your location does not have a specific code regarding the trench and back fill, you should follow ASTM D2774 Standard Practice for Underground Installation of Thermoplastic Pressure Piping. you can obtain this from https://www.astm.org/Standards/D2774.htm

This poly pipe system is great for installing underground propane piping. No need to join many lengths like with iron pipe. No need to dig straight trenches, we could curve it around obstacles. The riser elbows made the into and out of the ground ends easy.

You really need to fuss with this thing to get it to hold pressure. I installed 2 lines, one had a large leak that i eventually fixed with reseating the couplings, one had a very slow leak that i never got fixed. I verified that all other pipe fittings had no leak so it must have been these. I was hoping for an easy no brainer fitting, I don't think this one is it.

Hi Ironcore, Thank you for your feedback. We rely on this type of feedback coming in from the field in order to learn more about how and where our products are being used and what types of improvements we should make. I am surprised to hear that you had to "fuss with" the fitting to get a leak free installation. I am very interested in hearing more about your installation. Were our instructions easy for you to follow step by step? Did you fully tighten the fitting by hand and snug it with your pliers? Did you use the supplied insert? If possible, could you give us a call here at HOME-FLEX and provide some additional information? We are here M-F from 8-5 Pacific time. Our number is 661-257-3923. Ask for Jon ValenciaPipe

Worked like a champ
Rarely do I write a review for anything, but just had to on this one. This was my first time to ever install natural gas line, running a drop out to my new barn. Just follow the directions, super easy. Did a pressure test at 15lbs and held steady 24 hours!

Not Happy
I am a professional and have run many gas lines of various sizes in 30 + years. Against my better judgement I purchased these thinking it was good idea and 3/4" is generally easy to work with. I'm used to the sweeps having the stab fitting in place and just push the pipe inside. I have the proper chamfering tools for ease of fit. I did have to fuss with the 2 I had, to seal and hold pressure. Job took twice as long as it should have. I was cringing as I was tightening to finally seal off. Plastic like this generally jump off the threads when you over tightening. I don't recommend these coupling. Do yourself a favor and use the stab couplings from a plumbing supply. You can purchase an inexpensive chamfer tool online

Response from VPC, Home-Flex ExpertOctober 26, 2020
Hi, Poolguy86 - We're sorry to hear that you had a negative experience with our product especially since we have had thousands of successful installations. You mentioned chamfering tools. Please be advised that our HomeFlex underground poly pipe does not need to be chamfered. In fact, it's counter-productive. Simply ensure the pipe is cut cleanly, insert the stiffener from the coupler/tee provided, and slide the tube into the fitting bottoming it out against the black main body. Tighten the fitting hand-tight, then apply 2 pliers to the fitting and give it another 1/4 turn. No need to tighten too much. We invite you to refer to our very comprehensive and helpful CSST Design & Installation Manual at http://homeflex.com/downloads/HOME-FLEX_Installation_Manual.pdf. Thank you for your review. ValenciaPipe
