Blanking cap for 100mm waste pipe?

Mimon

Can anyone point me in the direction of one of these please.

Have removed the toilet from the ensuite for extra room and am looking to blank off the waste pipe.

Ordered a blanking cap from Screwfix but it is 110mm, just realised that my pipe is 100mm and scouring the interwebs cannot find one of this size.

Are you sure about the sizing, a standard 110mm blanking cap is designed to fit into the female/ socket end of a pipe which will have a 110mm internal diameter. Your pipe end may be the plain (male) end with a 110mm external diameter- to blank this off you will need to fit a coupler/ jointer, into which a blanking cap will fit! Don't know if you can get a cap that will slide over a 110mm plain end.

Thanks. Just presumed that the blank would fit into the female end of the pipe. Will have a look at couplers but measure properly first when I get home.

So if I bought one of these would it not just be able to fit into the female end of the pipe?

This is what I bought and is too big.

Only problem withat stopper is there is no rubber ring to make a gas tight seal so you can get foul air in the room.

Yes,

as Jack said it needs to be sealed properly.

Put grease on it, or for a permanent fix waste pipe solvent glue

Recommended to use silicon to create a seal with it.

What you've bought is a ( male ) socket plug,
it appears there is no (female) socket on the end of your pipe, otherwise it
would fit. For this to work you need a connector or sleeve .
This will fit down over the pipe and your blanking plug will fit into this connector.
Just make sure the sleeve you get is a double socket one with a rubber
gasket/seal on both ends to seal off any sewer fumes.
Alternatively ,just get the plug you linked to yourself ;https://www.screwfix.ie/p/mcalpine-dc4-bl-drain-blanking-cap-black/4331v#product_additional_details_container
This will fit down into the pipe and seal it,
and return the other one.
