PVC pressure pipe has some benefits relative to positive hydraulic transient pressure waves due primarily to the slower wave speed. However, I don't see much (any) documentation relative to PVC pipe performance or ratings under negative pressure. Does anyone have information whether the pipe...
That's the crux of the arguement down here. I think that the pipe is more accurately classified as fiber cement pipe. Given sufficient wall thickness it seems serviceable, I'm just concerned about its structural properties...especially impact resistance...as might be encountered by a backhoe...
That's kind of what I was thinking too, but didn't have any objective reason not to use it other than my ignorance of its long term behavior. Even on private property I'm a little concerned about professional liability if the pipe doesn't perform well (say under roadway/parking areas that might...
I think that the FRCP is different than the FRPM that you reference. My understanding is that FRCP is 'reinforced' with cellulose fibers (as opposed to asbestos fibers from an ealier day).
There's a fair amount of controversy in FL re: whether Fiber Reinforce Concrete Pipe (FRCP) is 'equal to' Reinforced Concrete Pipe (RCP). I think Hardie Pipe is the only FRCP manufacturer that I'm aware of. The main weakness seems to be proper handling/installation. If that's not done right...
