How to remove basin waste from bathroom sink?

[daniel4]

Hello everyone.

A quick question. 

How to remove Strainer Body / Basin Waste from Bathroom Sink without damaging the sink itself?

It looks like being glued using plumber putty. 

Below is the picture.

Thank you for your suggestion.

Regards.

Hi @daniel4,

Thank you for your question about removing your sink strainer.

The plumber's putty will have some holding power, but it is not likely to be the reason it can't be removed.

Have you got access to the underside of the sink?

There is often a coupling on the underside of the sink that can be rotated off to allow the strainer to be removed.

If this is not the case, is the central piece of the strainer a nut that can be removed? 

Some more photos might help to shed some light.

Allow me to tag some of our helpful members to see if they have any ideas, @Dave-1, @Noyade, @Nailbag.

Let me know if you have any further questions.

Evening @daniel4 

Are you talking about the four way cross part that you wnat to remove?

I havnt done a metal/chrome one before but have removed the plastic one from my sink after puzzling "how to" for a fair while.

First time I used a pair of long nose pliers and made sure I gripped the cross firmly, then a sharp "tugg" straight up (no sideways movement) and it popped right out. Second time (As I knew the process) I used an old toothbrush, pushed the head down through the cross and then lifts straight up.

I would also take a wander through a Bunnings store in the bathroom section and see if you can spot yours amongst the selction Then you can have a chat to the bathroom people and see or maybe actually see your model.

Hi @daniel4 

I recently had the same task which was a real struggle because the person (Not a plumber) who installed it filled the opening within the vanity with silicone which spread in to the thread of the drain. It's possible that though not to this extreme there is silicone on the large securing nut @JacobZ mentioned. I used a pipe wrench on the nut and needed a help to place a large screwdriver through the drain to stop there entire piece from turning. again some photos from underneath might help.

Hey @Nailbag @Dave-1 @JacobZ 

Thank you for your responses. Really appreciate those suggestions.

I managed to pull apart these components, please refer to these pictures below. Apologize for the grossness of the image

• It looks like there is kind of silicon or glue being used to attach this chrome strainer into ceramic. 

• I will try to use knife to remove this silicon.

Apart of this issue, I am just wondering with the build of this plumbing system in my 2x bathroom (both are in the same setup) are normal / following a current plumbing/building code. Home was built in 2010, location Perth WA. 

• The chrome strainer is tied with a threaded bar where then a  rubber (40 mm diameter) attached to the edge to the ceramic basin.
• Then all together are locked using wing-nut.
• Few of Water leak if the rubber is not forcefully fastened to the ceramic basin.

  

and the final operational is as below, where an S-pipe attached at the end of the vertical pipe.

My plan is to replace this waste system with the one below, so there will be no more water leak between ceramic and S-pipe.

Thank you all.

Regards, 

Daniel

Hi @daniel4, 

There's nothing there that would suggest those connections are not to code, but that's probably a question best posed to a plumber. If they are leaking then it would be worth replacing them. Please be advised that this is considered plumbing work and it requires enlisting the services of a professional to complete the work.
