Smell from drain

Spotty100

My heart is broke with trying to get rid of a smell from our kitchen sink drain. I think I've done everything I could reasonably do including having a man out with one of those cleaner things on the end of a high pressure hose to get rid of the gunk from the gulley. They gulley is only about 10 feet long by the way. Somebody suggested Chlorus which is used to sanitise milking parlous but I can't find it on sale in the UK. The sink and all its accoutrements is only about 18 months old and all of that has been well disinfected. At the moment I'm pouring Jeye's fluid down it and leaving it a few hours before putting half a bottle of Zoflora in and that gives temporary relief but I think I need to flush the gulley with something which will have a bigger impact on years of accumulated deposit which is still left there after the pressure cleaning.

Has anybody got any tips or ideas?

Is there a "U" bend in the pipe under the sink? If so there should be no smell from the gulley passing through the water in the trap. Get your pipework checked out. This assumes the gulley is outside?

Have you tried caustic soda ? If you dont have a U bend you need one.

Once a week we pour a kettle of boiling water down the kitchen sink followed by a gallon or so of cold water. The boiling water softens accumulated fat deposits and the flush takes it away. Never had any problem with the drain since we started doing this. Not much help to you at present! There are drain cleaning chemicals available, some are quite dangerous, so take care!

Do you have a dishwasher? we had similar problem with smell which we blamed on the gulley outside kitchen windows and put all manner of cleaners down the sink to no avail.I mentioned it to a plumber who was doing other work for me and he said to check the outlet pipe from the dishwasher.
I took the rubber outlet hose off and right away was hit by the same smell,turned out it was grease from the dishwasher lying in the outlet pipe.We got a bottle of dishwasher cleaner and run it through the machine and the smell was almost away at once,now we use the cleaner every 2 weeks and the smell never came back.

I also do as oldhand and use a cleaner in my dishwasher and also in my washing machine, on a regular basis.

At this time of the year, my outside drains get blocked by leaves, which can be a problem and I use a finer mesh to keep them out.

You will also have a vent pipe outside, which allows gases to escape from the drain and normally sited at a bathroom. If the top of the vent is blocked, this will create problems.

I an connected to a septic tank, which can be the source of some smells at the sink. I am assuming that you do not have a septic tank ?

Thanks folks, as well as all the Googling I've done you've helped my thought processes.

The only thing that has worked for me is soda crystals followed by a mug of vinegar

My drain is the same I was told to use white vinegar which I tried and it worked for about a week I have tried everything I can think off :-(

After taking all the advice offered, as well as using my own head, I'm inclined to think my problem could be because the gulley is venting into the sink. I've called the people who fitted the kitchen and they're sending a man out this week.

Certainly it seems odd that I've been treated the sink drain and the gulley itself for months and even after a high pressure cleaning we're still getting a problem.
