House was built in 1977, so we have cast iron pipes. We have a cast iron cleanout and our plug has gone missing. Went to Lowes to pick up a replacement, and we can only find 1.5 inch and 2 inch plugs. Problem: our cleanout has a 1.75 inch hole. Are our pipes so old that they don't make the size we need anymore, or did the previous owners jerry-rig this thing? Any advice on where to get the 1.75 inch plug? I've scoured the internet in search of one and can't find it.
