Sofa King Kule Posted May 25, 2021 Share Posted May 25, 2021 I have no idea why they are still made of cast iron. PVC won't rust and disintegrate, so, it won't have to be dug up and replaced every five years. Link to comment Share on other sites More sharing options...

Maybe it's a sort of trap to prevent the grease from congealing in the pipes. Link to comment Share on other sites More sharing options...
scoobdog Posted May 25, 2021 Share Posted May 25, 2021 In ground grease interceptors are made of concrete not cast iron. Link to comment Share on other sites More sharing options...

Concrete sounds like a good idea, too. To get more info on the trap, I'm about to show this pic to a plumber. Link to comment Share on other sites More sharing options...

I've never seen one myself, but it looks to be the right design for a grease trap and I don't think its unlikely that early models would be made of cast iron. Modern grease traps are significantly larger, making it cost prohibitive to make them out of cast iron. Also, PVC doesn't have the structural integrity to handle the size of a commercial interceptor.

Good to know, thanks. So, concrete is the better material compared to pvc. You taught me something. Link to comment Share on other sites More sharing options...
