[C320-list] Marelon seacock problem

[Scott Thompson]

I can find this part and the Seabung at Fisheries Supply in Seattle with 
two-day shipping and decent prices. I can't find either one at Catalina 
Direct.

But can anyone confirm that the appropriate size is 3/4"? They seem to 
have a range of sizes. This is for the sink drain in the head.
