Sea Chest Sea Cock

Darren Moore


We are hauling out next month and I'm looking at replacing the head sea cocks as they are quite stiff.
I've found the model number on the forum for the holding tank outlet - IBV-1250 BSPP
From measurement I think the raw seawater inlet to the toilet pump is IBV-750 BSPP 

I'd also like to replace the main Sea Cock to the Sea Chest, I've searched this forum but have been unable to find the size, does anyone know the size?

Thank you for your help
