Thanks for the help to all that responded. I met with the kids last night and they were impressed with all your reponses. The kids varyied in age from 10-15. I think they were just as impressed in that we have this forum to get real answers to scientific questions. thanks again.
What is the scientific name for rust or corrosion? How do you explain the delaminating of a steel beam that has been exposed to moisture. I need to talk to a group of kids about this, and I just don't want to say it rusted. PS this is totally out of my field, but have been asked to do this as...
Dear a31ford
Thanks for the help. I called Ipex Inc. and talked with a technician there. He said they do not address the problem of domestic lines in the cavity space of the heated area. He said this should be just common sense that any plumber or installer should recognize. But the bottom...
The question that follows the when will it fail, but "what happens next?" With a 48" dia pipe there is a lot of water and it sounds like you already have an erosion situation. What is on the lower end of this failure?

The unit will be used on a potable water reservoir overflow pipe. It is more of a security unit and to keep critters...

1. Is there a recommended material to use? I am not concerned with pressure or flow.
2. I am considering using Ductile Iron pipe. Is Ductile Iron pipe acceptable?
3. Is there any problems with material coatings during...

I need an old valve which has the glued body. The one I have is missing the internal...
I am with a Forensic Engineering Firm. We are investigating a failed check valve. The one in question is a CheckMate CV-200 by Liberty Pumps. I need a similar valve to disassemble. This valve has a yellow sticker and is round with a glued together body. Does anyone have one in stock or know...
