Steam Table

[Cwhyu2]

Why did the installer think it was a good idea to use PVC pipe only rated for 75 degrees F.

You would have to ask him. I assume this is a drain line and the connection to one valve has already "melted".

Yeah I know, yep drain.

I had nearly the same situation with a steam table in our church kitchen, (new building in 2011) however, the PVC was connected on the outside of the table but the heat from the burners made the PVC soft and allowed it to sag. In your situation it was the heat from the burners directly above it that got the temperature too high. With no support it folded over.

The 73 degree rating is for pressure rating and it is the baseline for calculations when using it deliver water. It's why CPVC must be used for hot water lines. PVC can handle boiling water as you pour it down the sink drain and it doesn't melt the PVC. PVC starts to decompose when the temperature reaches 140 °C (284 °F), with melting temperature starting around 160 °C (320 °F). https://www.google.com/search?q=pvc...j69i57j0l4.11194j1j7&sourceid=chrome&ie=UTF-8
