copper drain to ABS?

[generalinq]

Hi Folks,

I am pretty sure I have old copper drains (1 1/4 mabye..not sure)..

I want to install a new sink and use ABS for the drain. I don't need to attach it using one of those Fernco coupling's do I? I can just use a special ABS connection right?

We need more info.. What sink are we talking about kitchen, bathroom, laundry?

Hi

It's my bathroom sink.

You will need to use a no hub connector. It's similar to a Fernco but is used above ground. The reason is there is no other way to to make the transition from copper to ABS.

tell us exactly what is sticking out the wall and what size it is.

I doubt that your drain is 1-1/4". A bathroom basin trap is often that size, but kitchen sinks are usually 1-1/2", showers and tubs 2", toilets 3" or 4".
