What is blocking my Sink?

Question

For the 2nd time my Bathroom sink has become blocked. When we have unblocked it this brown like 'substance' has come up. It has no smell and I suppose it looks similar to the skin you get on custard/hot milk. (I know this sounds daft but we cannot fatom out what is blocking our Sink)

Answer 1

it could be the waste pipe is connected to your bath waste worth checking it out water could be backing up the pipe into your sink!

Answer 2

Quit pouring grease down the kitchen drain.

Answer 3

you could be getting feed back from some ware El's in the house

Answer 4

it could be makeup power or face and hand creams,hot water down the drain should help.

Answer 5

if someone washes their hair in the sink it could be hair gel

otherwise, I'm with "cg", the water isn't flowing so mould is collecting.

Answer 6

Orangey? Soap scum form liquid soaps, love.

Answer 7

As others have mentioned, I'd take the goose neck off and either clean it, or replace it with a new one since you have it out. You could also be picking up blockage material from elsewhere in the system, but I'd say that is less likely.

Answer 8

Take the water trap off from under the sink and see if it is blocked there.

Answer 9

You are & it's not a B/room sink it's a basin & Don I'll give you a thumbs up for your answer

Answer 10

Try pouring boiling hot water down the drain to clear the guk out.  Not really sure what is causing this build-up, but when you clear the block, it sounds like it is just making a ¨hole¨ through the guk - and leaving it there to clog up again.

There could also be something stuck in the trap that is causing some bacteria growth.  Try taking out the trap and cleaning it out with bleach before putting it back on.

Answer 11

Its probably a mixture of poo and wee.
