I need a new sink plug

[ProDave]

Well I don't but my sister in law does.

 

So SWMBO went to visit her and took one of our "spare" plugs 

 

It did not fit.

 

Of course I should have known, this is plumbing, there is no such thing as a standard plug.  So HOW do I go about determining what type / size it is to get a new one.

 

 

The top one is SIL's old plug.  the rubber is perished and it does not seal.

 

The bottom one is our "spare" one.  you can see ours has a larger diameter "boss" and the rubber washer but is akin to a low profile tyre rather than the high profile of the top one.

 

So what measurements do I need to take to work out which sort we need?

We first bought a replacement one from Amazon it fitted but was a bit rubbish after a week - so went to B&Q, they had two sizes, one being just right. That was a few months ago, all still good

It'll be quicker and far less painful to just buy a replacement unit and accept defeat. They're not more than a couple of £10's and they can guilt trip you into fitting it for free.

The failed one looks like this.  https://www.toolstation.com/mcalpine-bwstss-top-basket-strainer-waste-plug/p94986

 

The technical drawing looks correct https://cdn.aws.toolstation.com/items/manual/manual-bwstss-top-94986.pdf

 

If only they would put more dimensions on that drawing.

 

I will now do what will make all engineers shudder, scale from that drawing to see if it matches the one we want.

 

P.S I don't want to suggest changing the whole fitting because if I do, I know who will be making the 600 mile round trip to do so.

SWMBO visits every 4 weeks but she is no plumber.  I went once before to fix other issues and it has been plumbed previously by the plumber from hell.  I bet any attempt to do a simple thing like uncouple the trap to change the waste fitting will end in tears and a trip to the plumbers merchant.  So if a new plug will do it with nothing else, then that is good.

 

She has had great trouble finding plumbers, and any that have been have done the one job and never returned to do anything else.  I suspect they have all clocked how bodged everything is.
