Re: Thoughts on replacing bathroom sink drain


Thanks for the detailed write up. After reading that, I think I will just cut the right side of the existing chrome pipe that is sloped the wrong way so it goes down further into the fitting.
When I start simple projects it usually turns into something bigger. I will most likely end up re-plumbing the whole house from the sounds of it.

I am still having a hard time visualizing where the trap adapter would go?

Won't work. End of pipe has a flange on it.

Should not be difficult.
Sounds more difficult than it is. I could have done the job in a little more time than it took me to write it up.
(Of course I'm not very proficient at the keyboard.)

Re: Thoughts on replacing bathroom sink drain


Was just kidding about cutting the pipe. I want to do the job right. This "cob job" as Yoda called it was noticed when I was getting ready to leave from the last visit. (also put to work like a dog then) I told her next time I come down I would replace the pipes. Yoda and your advice are invaluable and I appreciate the time .

Like I said above , I am having a hard time visualizing where the trap adapter goes. Where does that get installed?

Re: Thoughts on replacing bathroom sink drain


Didn't get to finish the above,
Hard time visualizing where the trap adapter goes , vs where the pvc female adapter goes. I assume the trap adapter gets screwed over the iron pipe. What is the pvc female adapter for? Screw the female adapter over the male threads on trap adapter and then put the 45 street in the female adapter?

Re: Thoughts on replacing bathroom sink drain


A trap adapter is a fitting that screws on, or is glued onto a pipe. It is sized internally for a compression fit around 1 1/2 trap arm. There are two types. One that fits on a PVC pipe and one that fits inside a PVC pipe. You want the type that fits on a pipe. You will use the trap adapter to connect the PVC pipe and the trap arm. A trap adapter was used to connect the chrome to the iron pipe in the wall.

Not quite the same size as a regular 1 1/2" compression adapter. Don't get them confused.

The 1 1/2 PVC threaded adapter will screw onto the iron stub out pipe to convert to PVC. There are female adapters to screw onto an iron pipe and there are male adapters to screw into an iron fitting. You want the female to screw on the pipe.

If all goes to hell and you have to remove the iron stub out, you would use a male threaded adapter to screw into the iron tee (or ell) that is in the wall. Converting to PVC at that point. That would make the nicest looking job, but I wouldn't do it unless I had to.

Think about it like this. Once you replace the tail piece out of the sink drain and remove all the chrome junk, you will convert to PVC. The 45 turn at the wall will point you toward the sink. You can then install the trap and trap arm and point it toward the wall. As said previously you have lots of flexibility in the trap and arm to make them point toward the 45 at the wall. If all goes well you will use one piece of pipe to connect the to of them.

However, if they don't line up perfectly, a 22 1/2 somewhere along the line should make them line up. The closer the 22 1/2 is to the wall the more turn the PVC pipe will have. The closer the 22 1/2 is to the trap the less the pipe will turn.

It is hard to judge angles from looking at a picture but it certainly looks like you will need a 45 at the wall. It is possible that you may need to use a 22 1/2 at the wall, then use a short piece of pipe and then use another 22 1/2 to make the rest of the turn. A lot depends on how you position the trap and trap arm. However, I'm pretty sure you will be using a 45

Think about it like this, once you get the threaded adapter on, you are just gluing up PVC pipe.

You should worry more about protesters at the airport or that TSA agent that is having a bad day, making you miss your flight.

Re: Thoughts on replacing bathroom sink drain


Thanks HK, I couldn't get my hands around where to use the adapter, and where to use the trap adapter. Seems like both could be used on the iron stub out. If this were my house, I would not sweat it. But I have one day, the actual plumbing supply store in NC is closed on the weekend, and I will have to rely on the big box stock. And this is the bathroom I use when I visit.
Things clicked when you said:

You will use the trap adapter to connect the PVC pipe and the trap arm. A trap adapter was used to connect the chrome to the iron pipe in the wall.

Seems like the current set up used a trap adapter at the wall, and I just have to install the adapter on the iron pipe with a 45 coming off the adapter and use the trap adapter to connect the trap to the pvc arm

Thanks for your patience. Don't want the daughter to think the old man doesn't know what he is doing.

Re: Thoughts on replacing bathroom sink drain


P.S. Last time we went through the airport the wife got accused of having plastic explosives in her luggage. She had a wrapped block of fudge, the TSA fellow swabbed it and said it tested positive for explosive residue. Did everything but strip search her. Created quite a stir

Re: Thoughts on replacing bathroom sink drain


Just spent an hour online ordering all the parts. HD had them. Daughter will pick up the parts, primer, dope etc, and I will hit the door running.


Thanks for your help guys, I really appreciate it.

Re: Thoughts on replacing bathroom sink drain


Check local Home Depot and Lowe's for the 1 1/4 drain tail pipe before you go. They are available but are not needed that often. Those Sand Lappers may not recognize the name. Everything else are commonly needed parts.

Re: Thoughts on replacing bathroom sink drain


Neither. Both are tail pipe extensions.

The tail piece is a chrome pipe about 6" long with very fine thread on on end. It screws into the drain assembly.

I couldn't find a picture of one on the internet but I have seen and purchased them at Home Depot in the past.

If you can't find the tail piece alone, purchase a drain assembly. Remove the tail piece and use it to replace the one that has been cut off. The one that has been cut off will not be long enough when you get rid of all the chrome piping.

Some low volume items are not shown on Home Depot and Lowe's web sites. You should be able to fine it in the store.

This is why I suggest looking for it locally before you go.

If push turns to shove, I guess you could put one of those tail pipe extensions on the little bit of the tail pipe that is there now.

Re: Thoughts on replacing bathroom sink drain


That little tail piece that is installed has the drain stopper arm that goes through it. I think if I took that little tail piece out, I would have to replace the whole stopper assembly. I have ordered the extension and the tail piece, and multiple extra parts. We will see how everything matches up.

Re: Thoughts on replacing bathroom sink drain


Just finished up the project. Ended up with this. Success I think?
A little tight threading the adapter onto the iron pipe, no leaks!

Don't know why I can't get the pic to rotate

Re: Thoughts on replacing bathroom sink drain


Congrats. Looks good to me.

Looks like you had enough of the tail pipe left to attach the tail pipe extension.

Re: Thoughts on replacing bathroom sink drain


Just enough and I only had to use about a four inch section of the two foot piece of pipe I bought. Thanks for all of your help. Project went a lot easier with a little advice and having a parts list before hand.
