My moms house was built in the mid 60s and has copper DWV, except for the main stack. I am going to install an Insinkerator Evolution Compact to replace her old unit and was thinking I should do something with this trap (which some of you guys who do this for a living might have seen before?). I know I can use a 1-1/2 inch copper DWV C x SJ Trap Adapter, but I was hoping for a cheaper solution like a Fernco adapter. If so, can you suggest the proper adapter to connect 1-1/2 inch copper to a 1-1/2 inch PVC trap?
