Ever since moving into a 2004 built Barratt home in 2006 I have suffered with a very slow draining upstairs bathroom sink. The toilet and bath have no problems what so ever. I have had the u bend off and don's see any problems. I have also used a vacuum style plunger which used to improve the flow but now when you use it (it uses water to flush any blockages out) it causes water to come flooding from the bottom (never used to?? ) so I cannot use this method anymore. I have also used chemical liquids to shift any possible blockages too but I am now thinking it isn't a blockage and the way in which it has been plumbed in could be the issue. I am afraid I am a complete amateur in these matters so please don't get technical lol!

Sounds like it's time for the big guns. Purchase a hand snake, (see image)and remove the "J" bend from the trap. Send your snake up into the wall,(see image). You'll run into a bend about 8 inches in but once around that you only have 6 more feet to put out. Flush with a pan of boiling water. Good luck and thank you for rating my answer. Tom

Hi, Many thanks for your suggestion and your help speedball1. I went out and purchased what you suggested and have tonight fed the metal coil right up to where the drain exits out of the wall and there is no blockage (which I suspected there wouldn't be). Can you suggest what I should do as a next step?

Do you mean you went down the drain instead of the trap?(see image) You must gi in the wall through the trap bto sake the horizontal line in the wall.
If youhave snaked the hoeizontal line then the blockage's downstream and you will have to rent a sewer machine<(see image) and snake from the lavatory roof vent. Put out enoughcable and 15 feet more to get out in the nain. Goodluck and thank you for rating my answer. Tom

No, what I meant was that I took the pipe off (the one that's under the sink and shaped like a U) then fed the snake into the exposed pipe leading down then left towards the back wall of the house. It would go no further than that because it wouldn't.

I found your message difficult to understand as I think you have typed this in a hurry. Please explain further if I have done something wrong with regards to the snaking.
