Bathroom Sink Drain-flange repair
 
Last night my bathroom basin/sink leaked by where the drain pipe joins the bottom of the sink - when I examined the flange at the drain hole - it had corroded at the threads/joint and basically broken off -

I may be using the wrong terminology -
so here are some pics -

There is obviously a gap now at the joint -

I thought it might be simple to repair - just take the flange to a Home Depot/Lowes and ask what I need to repair this ......

But I thought I'd ask here first
- what parts should I be getting, please?
and any hints/advice in making this repair.

Also the pop-up plug is now broken at the point where the horizontal pivot rod/actuator connects
- what do I do to ensure that is adjusted correctly for the new replacement - so I don't break the new one too, and the plug seals well enough so it does not leak?

Many thanks for any advice or pointers to instructions.

As long as there is no damage to the sink itself, you probably only need to replace the pop up drain assembly. This is only an example. You can get them in most finishes, and probably cheaper than this one from HD...click this link and it will show it to you...

Oh, and WELCOME!!!!!!!!

Hack has got it right. Do yourself a favor and don't buy the extra cheapo one. It will leak at the ball joint that pops up the stopper - right away or later.

Speaking from experience. Put a magnet on the new one and if it sticks to any part, get the next better one.

A handy tip... Get a small tube of plumber grease while you're at it, and grease the threads before installing it. It only costs about $3 and will really help the rubber seal slide up against the sink and will help when tightening the nut. Also, some grease around the ball of the pop-up lever will help it operate smoothly.

And don't forget to use plumbers putty on the new drain. Just roll it in your hands to make a 1/2" to 3/4" thick snake and place it around the drain where it will meet the top of the sink. Unless you sink is cast it is probably fine. if there is damage to the sink you will 1 replace it or 2 need to rebuild the damage with epoxy. Not an easy task if your not experienced.

Thank you for the kind responses.

I took just the top flange to a Lowes - and they don't sell just the flange - they had the entire kit - like Hack showed above - these were in the $11-$25 price range in the stores I looked in - they're 1-1/4" pop-up drain assemblies.

So far, I can't see much, if any, real difference between them (but I will use travelover's magnet tip) - I will probably just buy an entire assembly.

Fitting does seem commonsense - and I already have some plumbers' putty and teflon tape for the job.

Thank you again for the responses, and kind advice.

The cheap ones have a chrome plated steel rod that operates the popup through the ball joint. It rusts off and then you have a leak underneath. Yech.

Got you -
my current one is nylon/plastic -
I'll look for nylon/plastic
or something non-magnetic
(although stainless steel is still magnetic).

Thanks,

Better quality have brass or stainless rods for the pop-up. Other differences are the tail piece that connects to the drain is plastic (the threads strip easily) or thinner metal (corrodes quicker), the seal around the stopper sometimes leaks (hear a trickle when the sink is full), and I could probably think of more. You get what you pay for.

If you hold the two of them, one in each hand, the more expensive one will weigh more. That's because they put more brass/stainless into it.
