thanks for advice allo, kkman what does trap under the sink mean?
its an s bend in the water pipework under the sink. the bend causes a water trap which does not allow smells from the drain to enter the kitchenthanks for advice allo, kkman what does trap under the sink mean?
there might not be a problem with your machines at all. sometimes dodgy plumbers install washing machines without a water trap. washing machines, dishwashers and sinks should all have an s bend water trap, otherwise you will get what you described as a "noxious whiff". no need to move your machines at all i suspect..We are in the same boat as the OP - kitchen is plumbed for washing machine (which we have) & dishwasher (which we don't) From time to time, we get a noxious whiff in the kitchen from the sink. Neighbours with a dishwasher plumbed in don't have this problem... so we're moving the tumble dryer to the shed & getting a dishwasher next week!
Is it possible that where a dishwasher or washing machine is plumbed into the waste pipe of the sink, that running one of those appliances causes the sink trap to be emptied, thus breaking the water seal and letting stink in?
I''m thinking in terms of the machines draining causing suction which pulls the water out of the s bend, is that possible?
Also possible that the appliances don't have a trap. Anything is possible based on cowboy builders or bad DIY.
