Bathroom Sink Coupler Down Pipe Issue

[davidfredlee]

Excuse me for my lack of knowledge in this but i'm a first time buyer so this is all very new to me. Last month i moved into a property in SE London which seems to have developed a bit of an issue since the weekend. The back of the bathroom sink isn't connected properly - as you can see in the picture below the upper (white part) of the sink should be connected to the grey pipe but doesn't appear able to grip it due to the weight of the grey pipe. I've tried to buy parts to join the two up tightly but had no luck with sizes. The white bit measures 5.5cm in width and the grey pipe around 3.5 cm width. Another troubling thing is the fact that the grey pipe can be moved up and down quite significantly - is this normal? To be honest i'd have imagined that it would be fixed and not resting in the floor like it is. It looks like there is soil around the pipe entry to the tiles, but i'm presuming this is mould or dirt from dripping in the past - can anyone confrim this?

Any help would be wonderful!

THanks in advance.

David

Looking at your first picture:
1. Unscrew the knurled nut at the bottom of the white pipe.
2. Inside should be a conical black rubber washer and a plain plastic (usually blue or red washer).
3. Clean the pipes up.
4. Put the white plastic nut over the black pipe, in the same orientation as your photograph. Make sure it doesn't slide too far down the black pipe, perhaps put a bit of tape on the pipe.
5. Slip the plain plastic washer over the black pipe and let is slip down inside the white plastic nut.
6. Put the conical rubber washer on the black pipe, with the narrow part of the cone facing upwards. It will be a slightly tight fit. Push it down so that there is about 15 mm of black pipe showing above the edge of the conical washer.
7. Push the nut upwards on the black pipe, and screw it onto the end of the white pipe. Firm finger tight should be enough, but as its been used, firm finger tight plus 1/4 turn might be better.
Doing the above should provide enough grip to stop the black pipe slipping down again.

If you need to replace any parts, you need a basin (not sink, which are larger) waste. Get a Mcalpine X10 and just use the parts you need.
