Basin Waste Leak (bathroom)

[luca T]

I inserted a Round Plated Heavy Push Button Slotted Sprung Basin Waste per this link Round Plated Heavy Push Button Slotted Sprung Basin Waste into my bathroom basin. I Used this 3 part basin waste seal per this link Basin Mate | 3 Part Basin Waste Seal Kit | Stevenson Plumbing & Electrical Supplies which results in no water leaks. However, a small seepage of water seems to come out where the red arrow is in the picture from the white pipe joint instead. Can anyone suggest what is best option(s) I should do to stop the leakage? I used no silicone or sealant per the manufacturer guidelines on the 3 part basin waste seal. Perhaps the pipe needs to be replaced. The white pipe end seems to just sit on top of the metal sprung basin waste unit & doesn't extend fully inside of the basin waste unit which would create a great locking fit. I put a bit of plumbing tape around the piping joint connected to the metal waste unit. Because of the size of the 3 part basin waste seal in the picture I can't tighten too much more without a risk of over tightening.

youve put the 3 part basin waste seal basin the wrong way round

seal pointy end up
then white spacer
then 11/4 nut
then the trap

Do these basin mate things actually work? Which wastes do people purchase these days that don't need silicone, putty etc?

I had a waste where I had to cut the white nut down.
