stinky kitchen sink

Nicola135 · 30 Apr 2014

Occasionally there's a horrible smell coming from the kitchen sink ... I did have a plumber take a look a year or so ago and he suggested it might be 'just the way the wind is blowing'!

It's fitted with a U bend and (very very) rarely does food debris fall down the plughole (we're a tiny charity using an office and kitchen in a 7 year old building - we're responsible for the cost of repairs).

Any suggestions as to what I could do to resolve the matter.

Many thanks!

Put the plug in, fill it up and check the overflow isn't blocked.

If the sink has an overflow, try putting thick bleach down it, debris collects in the overflow and can cause a stink.

EDIT: two posts at once!

If you're confident, take overflow off and wash it in another sink, as said these trap stuff and its rots and stinks. Make sure no-one uses the sink when its out

Thank you for your helpful suggestions.

The overflow isn't blocked but it did remind me that the sink is so rarely used there's never fresh water going down there.

I'll try bleach next .... thus delaying tackling removing the overflow myself!

Thanks again

Another option which has worked in our kitchen sink in the past (without full dismantling) is to tip a decent quantity of distilled vinegar down the waste and try to let it stand for a few hours or overnight.

Then rinse through.

Repeat every few months.

It has worked for us and very low cost <£1 for a bottle from the supermarket and probably more enviro friendly than bleach. Worth a go.

Maybe the water in the trap has just dried out, letting sewer smells into the kitchen. Tip some water down it and see if the smell stops.
