Q:Since my pipe is already been installed under ground. Finding the marking would risk more damage. What is the size reference, ID or OD? It looks like I need to order it, AKA I need to know! Thanks
by|Nov 29, 2022
1 Answer
Answer This Question

A:  Hi, CrazyFrank - Pipe measurements are ID. However, since you have 1-1/4" pipe, it would be good to know the OD as well. This is because that particular size is sometimes used by municipalities and private gas companies using a thicker wall. This is shown by the "SDR" or "DR" reference on the pipe. Most frequently used is SDR-11 and the coupler you reference will work with it. Feel free to call Dave (x1026) or Jon (x1010) at (661) 257-3923 M-F 8a-5p to discuss if you'd like.

    Q:Does this will work for sdr 10 1 1/4 pipe and where can I find a reducer 2x 1 1/4
    by|Oct 16, 2022

    Answer This Question

    A:  Hi, Juan - No, the coupler you mention will not work with SDR-10 pipe. However, we do make an SDR-10 1-1/4" x 1-1/4" coupler. Part number 18-429-012-10. It's not a stocking item at Home Depot, but you can order them on homedepot.com (https://www.homedepot.com/s/18-429-012-10?NCNI-5) or from your store's special services or Pro Desk. We do not make any reducer couplings but you can use our 2" and 1-1/4" transition fittings with a 2" x 1-1/4" bell reducer in between them. Note that the transition fittings are SDR-11, however, and won't work with your SDR-10 1 1/4" pipe.

    by|Oct 17, 2022

      A:  When I bought everything for my project I made sure all my fittings and pipe were the same, in my case SDR 11. I don’t believe the homeflex makes reducer. I couldn’t find one. You can buy the underground Transition piece and maybe do it that way 

      by|Oct 17, 2022

        A:  Will work for 1.25 " pipe if you have the 1.25 coupler. I don't know about the reducer.

                  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.

                  Response from VPC, Home-Flex ExpertAug 14, 2017
                  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

                    Experienced at leak at one of these fittings. Ultimately identified a small nick on the plastic piece that creates the seal with the propane line. Ordered a new fitting and that resolved my issue.
