Blocked kitchen sink- help

crockpot

My kitchen sink is blocked again!

I think it is more a problem with the sink and pipe than what goes down it, as I do not use cooking oil and have one of those meatal things with small holes in to stop most things going down the plug hole!

I have tried `plug unblocker` fro wilkco-bought on special

Bicarb and white vinrgar

boiling water

bleach

drain outside is fine and sink does not have a u bend- its `lead` pipe thing old- think my kitchen is about 25-30 years old?

Any idesa, do not want to get a plumber in

You haven't mentioned a plunger. You can buy them cheaply in Poundshops, Wilkinsons etc. Cover the overflow hole with a rag and get plunging... will shift most things!

If that doesn't work I can't help thinking that the only answer would be to replace the pipes with modern plastic ones and a U bend. Then it would be easy to deal with problems in the future. It sounds like you have tried everything with the present system.

I'll second the plunger suggestion - my sink was clogged solid with 15 years worth of coffee fines (the powdery bit of coffee grounds which had set like cement) - I was on the verge of using dynamite when I tried the plunger - hey presto, one clear set of pipes, and much safer than the lethal chemicals I had been pouring in for days.
Cautionary note - be VERY careful about using a plunger if you've already poured chemicals into the sink; the pressure could force the chemical into your face, so mask-up with safety gear.

You can get those thin flexible wire thingies with a handle on the end, which you shove down the plughole and then turn... I got mine from B&Q and it's far better than any of the horrible chemicals!

Plungers are also fantastic as suggested above!
