Alan, thanks for continuing to stay in this! I appreciate your help.
What coincidences! The elbow you found is the one I also found late last night. It is manufactured by Normandy Products and it does seem to be built on a bit larger radius than what I've been seeing:
I found it available for retail online sale from
Drainage Solutions. at a lower price than Southern Pipe & Supply ($22 vs $32) and shipping costs from Drainage Solutions strike me as reasonable for the market today.
Yes, I did find the SDR 35 8" straight pipe and fittings locally at Ferguson Waterworks. They only have the gasketed pipe, but their price is not terribly bad at $57 per 14' stick (ouch!, but I only need 3), with free local delivery. Their sales guy searched for me to see if he could source any weld end pipe, but no luck. Nor did he have access to any D-2729 8" pipe. So, I'm planning to use the SDR 35 for my 8" pipe.
I haven't found a local source for 6" D-2729 pipe. I was able to find it in Richmond 3 years ago, but nothing in this region. However, McMaster-Carr does carry it in 10' sticks at $32 per stick (
link here) and their shipping cost is not unreasonable. Plus, if I end up ordering some other items from McMaster, they'll try to fit it all on the same pallet to ship.
Yes, the 8" fittings are expensive, but the sales guy I talked with quoted me some better pricing than you're seeing on their online price list. Also, Drainage Solutions has it for less (e.g., $66 for the 8x8x6 45 wye vs. the price list of $113) and I think Ferguson may match those prices.
For the 6" D-2729, I think I paid about $25 per 10' stick in Richmond three years ago. I understand the price of materials has skyrocketed and availability is really down right now.
Thanks for the link to SiteOne! They do show the D-2729 in stock in Huntsville, and I may have someone who can buy it for me at contractor rates if they won't deal with me directly. I'll have to look into this. It would be great to be able to buy locally and not have to ship it.
You have a good suggestion for using the bell ends for connectors.
