Replacing drain in bathroom

I'm replacing the 1 1/4" pipe that runs from the main drain pipe in the wall to the inside of the room. This was a very thin piece of copper pipe that was actually soldered into the main drain pipe.I removed it and was wondering if there are any alternatives to replacing this old pipe besides soldering it. It looks like there is a ring that the old pipe was soldered inside of. It almost looks like a reducer. Can this be removed so as to expose the threads for install of a more typical threaded pipe? thanks, Owen

Re: Replacing drain in bathroom

Your main goal is to get a solid, water-tight seal that will last for years.

If the drain pipes are clearly visible to anyone using the bathroom, then asthetics comes into play.

The most common drain parts being used now are white PVC plastic, connected with screw-on connectors, and in some cases, PVC cement glue, because they're so widely available and have the lowest cost.

You'll see the plumbing section bins at the home improvement stores loaded with this type of drain pipe.

There is also still a lot of chrome-coated thin copper/brass used, but this is more expensive, and is becoming harder to find as world copper prices skyrocket.

Chrome-coated copper/brass may be more tolerant of drain cleaners, and the connectors are more easily tightened.

Care has to be used not to tighten plastic connector nuts too much, or you'll strip the threads.

Both types are widely available at the home improvement centers; take along a measuring tape and see if they have any pieces either plastic or chrome that you can match up with what you have now.

It should be noted that you can easily remove the chrome covering from any chrome piece with a piece of emery cloth/sandpaper if you have to solder any piece.

If appearace is not a big issue, you can spray paint the soldered drain pipe parts with black paint.

Plastic to copper to chrome drain pipe can be inter-connected with pipe cement, solder, compression fittings (screw on) or fernco fittings.

Make sure you include a P-trap on your repair fix so that sewer gases are prevented from entering the bathroom.

This repair is very similar to repairing kitchen sink drains; so check the piping under your kitchen sink to use as a guide.

Scroll down and click onto the "search box" at the site below and enter "connecting the sink plumbing" (without the quotation marks) in the search box.

Also Google "installing a bathroom sink drain", without the quotes, to get more sites.
