As most of us saw in a topic a couple of months ago, ABS also shattered. It was cellular core, which is the same as what you probably used. And anyway, I would much rather use DWV PVC than ABS, because I know DWV PVC can at least hold
some pressure.

look . i am tired of you telling me that abs can not hold pressure, because i have hade a piece of abs pipe at 120 psi for half an hour and it is in one piece. they pressurize that pvc pipe for 5 seconds and booom , pipe all gone. and if you call that video holding " some " pressure, i call that blowing up with "little " pressure. so if you got a problem on how i make stuff go cry to ya momma or something. this is a web site for ideas and people to show off their cannons not for you to tell people lies about ABS pipe. sorry for anyone else readong this, but i am just a little mad right now.

ABS is used in irragation systems and can handle some water pressuse but not that much coz it ruptures.
