How to fix bathroom sink drain pipe ?


While I fixing new faucets, the bathroom sink drain pipe is punctured. It seems that area was already damaged.. I am not able to figure it out whether it is threaded or soldered..

Here are the fixtures.. Can you please let me know how to fix them ?

Now I just need to get a connecting piece, right ?

How do I measure the length ? or should I carry broken pieces to HD to get a matching one ? or is there a standard length and angle for this drain pipes ?

That's a standard p-trap. But it's always good to take the parts with you to your local hardware store to make sure you have the right diameter, etc. The length of the pipe that runs horizontally into the galvanized pipe may need to be shortened. Use the old piece as a template. They are easily cut with a hacksaw or reciprocating saw, then deburr the cut edge with a file before installing.

It looks like this trap is located in a cabinet. Since it is not a cosmetic issue I would replace with a PVC trap instead of using brass like your existing. Easier to cut and install. And much cheaper.

Thank you for all.. I bought plastic P trap and fixed it..

However, there is still one issue.. the drain line going out has metal nut and since my P trap is plastic.. I am not able connect these two pieces correctly.. this is causing leak..

Platic nut can't go through the steel pipe I have it.

Here is the setup. I don't have steel nut to for the sink pipe. Either I have to purchase the steel nut so that I can fix the steel trap..


Or
to fix the plastic one, I need to take off the steel pipe from drain line, which I don't want to do.. unless I need to.. since this seems to be more work here.. if I do this, then I can fix the plastic one end to end..

Any other thoughts ?

Normally this stuff just screws compression fittings. If I couldn't get it off I'd cut it with a hack saw and go back with plastic fittings you can find a Lowes or Home Depot. The black plastic in the back I wouldn't cut. If you twist on the threaded end (rightie tightie lefty loosie )it will come loose.

You shouldn't have a problem going metal to plastic, but if nothing worked you may need to replace the material into the sink. Probably needs a new drain anyway. Normally a bathroom sink is 1 1/4 inch pipe but to the prior post take the pieces with you to the store and buy extra parts.

Whenever I replace these I start at the wall and go into the sink with all new.
