Thanks. I knew some DUMMY would bite
I think I have a few lengths of Orangeburg under the barn
I was wondering when someone would mention SDR ("Standard Dimension Ratio") pipe. Spinner, would the pipe you installed be 11, 26 or 35? 35's a bit thin walled but legal in CA for building sewers. I remember testing my first SDR 35 lateral with water and having all the cleanout risers pop out of the combos due to pressure. Removed the CO plugs and eliminated the problem. Learning curve....
SDR-35 for gravity, 21 for force mains and water. What were you testing to that the co's would pop out?
Building sewer tested to grade. No place for the displaced air to go. Gaskets wouldn't hold. Risers popped out of the ground.
i need to rephrase that what pressure were you air testing the SDR to? Normally we would only pressureize to 5 psi
Although we've used ABS for years here, I'm seeing more PVC at the supply houses. It's true that PVC is superior to ABS. It isn't perfect, though. For example, never cut PVC in cold weather. Make sure the room is about 50 degrees minimum or the stuff shatters like glass. It's really annoying to shove a piece of pipe into a tee and have the tee go to pieces.
And PVC also tends to make more noise than ABS. It will squeak like a mouse being drawn and quartered when expanding against wood splinters. (Don't ask me how I know about the mouse . . .)
And the reason there's cell core ABS is because manufacturers wanted to make more pipe with less raw product. I would far prefer to use the original solid pipe.
