Installing a basin waste.

[ShaunCorbs]

Yeah that's true, gotta be a cheapo Victoria plumb Chinese special then...

Yep looks that way

You have two options op

Either replace the waste fitting (best option)

Or you could cut or file the lip down to fit the waste fitting

 

[ShaunCorbs]

What's up with it?

Waste wall thickness out of spec

 

[Ellis01]

It is a mcalpine. Just checked the packet. I will get another click waste tomorrow

If it is close to the size, all you have to do it remove the rubber seal temporarily while you file the bit at the top of the trap down.
Just to be annoying, I am going to add that the tap flexi shouldn't be tightened onto the isolating valve. The valve is not designed for flat washers going against it. Some plumbers do it though.

is this a wind up

is this a wind up

what do you mean?

 

[Ellis01]

Oh okay. I didn't know that. What should the tap flexi be attached to?

 

[Riley]

15mm to 1/2"male iron

 

[Ellis01]

OK thanks. I will pick some up tomorrow.

 

[ShaunCorbs]

OK thanks. I will pick some up tomorrow.

will need a short piece of pipe between the valve and male iron

Take a Stanley name knife and shave the top edge of the trap down till the rubber meets, I've had to do this multiple times with cheap bathroom wastes

Had this problem a couple of weeks back, Victoria Plum waste is a different size and will not fit normal waste traps like a McAlpine.
I had to get an adaptor made by McApine to screw onto the Vic Plum waste.

Victoria Plum sell their own traps which fit their wastes and funny enough they are more expensive than McAlpine.

Edit- You need a McAlpine S12A-F 1 1/4 European to UK waste outlet adaptor.

Learned that one 30 years odd ago when pop ups 1st came out. Leave a mill or 2 enough to hold the washer in place or you will be there all day.

The wastes are not necessarily cheap, just euro sized.

Normally just below/ flush with the rubber works
